Essentials of a Solar Greenhouse

Plant breeding and plant production is a very productive hobby and livelihood. It is good way to earn a living by producing high-valued crops. It is also a good way of contributing to the environment. The best way to sustain this endeavor is to get a solar greenhouse. Read on to learn the basics of the solar greenhouse.

What Is a Solar Greenhouse?

The very purpose of any greenhouse is to collect solar energy whenever the sun shining high. However, solar greenhouses serve a more specific purpose. It is able to do more than collect the solar energy. The solar greenhouse is able to store heat that can be used during nighttime, cloudy days or the cold season. It provides adequate heat that the plants will need for their growth even during the night time or the cold seasons.

The good thing about solar greenhouses is that there are choices to choose from and to suit the needs of the owner.

They can stand alone. This is very ideal for big production greenhouses. The freestanding ones are ideal for commercial production. These are used to produce ornamentals or vegetables. They have two primary designs, the shed type and the Quonset type.

The shed-type has a long axis running from the east to the west. It has a south-facing wall glazed to collect maximum amount of the energy from the sun. The north-facing wall on the other hand is very much insulated to avoid heat loss. These features are what contrast a solar greenhouse from the ordinary ones.

The Quonset type can sometimes look like an underground pit. This is a low-cost greenhouse. It has a Quonset-shaped frame and looks like a tunnel. It has a layer or two of plastic film. This can save as much as 40% of the heating fuel.

They can also be merely attached to the greenhouses, very ideal for backyard use. The attached solar greenhouses are structures that form some sort of a room protruding from a house. This is a good space for transplants or herbs.

Passive or Active

The solar greenhouse is classified into two. It can be the passive solar greenhouse or the active. These two makes use of different resources, but still serve a same purpose.

The Passive Solar Greenhouse

In some places, where colder seasons tend to endure longer, there may be a need to resort to passive solar greenhouse, using gas or electric heating system. This is the only way to protect the plants from getting too much cold. This is very ideal for growers as it can still give way to so much productivity despite the conditions. The use of heating systems for greenhouses to be cost-effective is best utilized if there are high-value crops to be produced.

The Active Solar Greenhouse

The active solar greenhouse makes use of supplemental energy. It transfers the solar heated air from the storage area to the other parts of the greenhouse.

Designing a Solar Greenhouse

Most would claim that managing and maintaining an ordinary greenhouse does not differ much with the solar greenhouse. However, there are a number of ways that they differ. These are significant distinctions.

Solar greenhouses, unlike the ordinary ones, have oriented glazing to get utmost solar heat, even during winter. Its materials are designed to minimize loss of heat. It uses heat storing materials. It also has insulation especially useful when there is no sunlight. The solar greenhouse also depends heavily on natural ventilation for cooling during summer.

Solar Heat Storage

This is one main feature in designing a solar greenhouse. To remain warm even during cool nights, there must be sufficient amount of solar heat stored. One common method used to store this energy is to put rocks or concrete directly receiving the sunlight to absorb the heat.

Cinder block walls at the north side of a greenhouse are also used as good heat storage. Dark-colored ceramic floorings can also be used to store the heat. Any wall or flooring not used for heat absorption is supposed to be colored light. This should be designed to reflect the heat and light and distribute it to the plants.

The management of a greenhouse can also determine the amount of heat stored. A greenhouse that is full of plants and structures can store heat easier compared to an empty one. Composts can also complement the heat storage goal as they help produce carbon dioxide in the atmosphere. Furthermore, the microorganisms in the compost also contribute to the increase in plant production.

Some would rely on any structure that would resemble a greenhouse to accommodate the plants. However, to be efficient and cost-effective, aim for the optimum setting in your solar greenhouse.

Top Tips To Find The Best Greenhouse For Sale

After you research the best greenhouse for sale, then guy it, there is still the problem of builing it. Building your own small greenhouse can be a very enjoyable and educational experience as well as economical especially when you are clever with tolls.

Select a well-drained and level lot or ground for your greenhouse. If you will be using it mainly during the summer for propagation of plants, then you can situate it in a partially shaded area to reduce heat buildup.

The “north side” of your yard, with a big deciduous tree is an ideal location. If there is no partly or moderately shaded area available, you can make use of a white plastic or shade cloth for cover so as to regulate the extent of sunlight that reaches your greenhouse interior.

If you will be using the greenhouse for beginning transplants or that you will be growing plants till they mature, your greenhouse should be put up in an area will it will have the highest sun exposure. Likewise, it must be situated where there is good air drainage; do not construct your greenhouse in low areas which are surrounded by buildings or woods. Consider also convenient water access and electricity.

No matter what kind and greenhouse dimensions you choose, take into consideration the time that you will have for managing the system.

Never be overly ambitious, as there are several new owners of a greenhouse that often realize they can not spend sufficient time as they had believed they would. However, it is not often true that a greenhouse requires continuous attention.

The greenhouse environment may be sustained with very minimal maintenance using automated controls that operates the ventilation, heating, humidity, artificial lighting and watering, should there be no one to look after it. A hobbyist must take into consideration installing automatic control system and begin with plants that are easy to care.

There are many prefabricated greenhouses available in the market that you can purchase, or your greenhouse maybe built out of very simple frames, though make sure that only certified plumbers and electricians must install your automatic systems.

Kits are widely available in various prices, materials and styles, but if you are an eager “do-it-yourselfer”, your small greenhouse may be affordably constructed for a comparatively small amount of cash. Lean-tos type of greenhouse can be built leaning against a garage or a house taking advantage of the existing wall, though one has to consider sitting space.

The major advantage when you choose to purchase a greenhouse kit, many details like how to deal with humidity, ventilation and leakage have been already dealt with and considered in the pattern. Someone who is constructing the greenhouse himself must consider all these so as to avoid problems that can result to untimely failure and plant loss. Here are tips to help you build and design your own small greenhouse.

1. Begin with an average design using materials that are easily available. Know your preferences. Attractive greenhouses may be constructed using recycled materials such as remilled wood, repurposed doors and window sashes.

2. Adapt to your area’s climate so as to make particular solutions that depends on your climate and location.

3. Plan a design that can use standard material sizes, most of which are available in “multiples of 4”.

4. Take into account your habits in gardening when planning the design. Growing vegetables is very different from growing vegetables.

5. You can set up timers and thermostats to regulate the precise heat or light needed.

6. Design and make a “back up” arrangement just in case of power failure or harsh weather conditions.

7. When you will be using wood, you can build the greenhouse from cedar, redwood or cypress, although regular wood treated and painted will also do. Make sure that you use wood that is pressure treated for framing, as it is an effective and economical.

8. Usually a greenhouse uses “glass-paned”, but polycarbonate plastic, fiberglass, plastic film and acrylic can be also used. Each of these materials has its disadvantages and advantages, so you need to research well to decide on one that is best for you.

9. Although permanent foundations are recommended to support the structure, flooring is really not necessary. Flooring poured with gravel up to a few inches deep will permit ample drainage. A flat stone or concrete walkway between seating will provides steady footing.

10. You greenhouse design should have enough room for tall plants and plants should only use half up to “two-thirds” of your greenhouse area and the rest is reserved for benches and your work area.

Have fun!

What portable greenhouses do? Portable greenhouses, just like the traditional ones, trap heat coming from the sun during the day through its covering and keep the heat radiated by the soil during the night to keep the surroundings warm enough for the plants. When a portable greenhouse is closed, it also traps in moisture which helps reduce the frequency of watering the plants inside.

A portable greenhouse is ideal for early planting of seeds, protecting the tender plants from the cold climate, starting perennial seeds in summer, fast rooting because of the need to transplant, and growing different kinds of plants that are not commonly grown in the area. This can also be used to overwinter plants especially when heated.

Portable greenhouses becoming popular Gardeners are being continuously interested in these portable greenhouses and increase in sales of these products is evident. For one, these portables take no time to set up to get them going right away. Taking them down when it is not time to use them is also hassle-free.

These big ones can fit up to 3 to 4 bigger shelves inside.

Gardening Tips Weather can really be unpredictable. So when a sudden cold snap occurs, burlap sacks filled with leaves can be thrown over the sash on the frame or covering during the night to prevent too much cold to get inside. Bales of straw or hay may also be stacked against the frame.

For extreme summer sunlight protection, some sort of shading can be used to prevent plant damage. Examples of covering that can be used as a shade are knitted shade covers, old bamboo blinds, and lath.

Plants inside the greenhouse should also be watered as early in the day as possible. This is to allow for quick drying of the soil before it gets dark. Improperly managed drainage and keeping the soil wet can pose problems later on and may not be a good gardening experience for beginners.

Whether you are a novice or is already an experienced gardener, having a portable greenhouse may be beneficial to your gardening needs. Being able to transport your greenhouse in a convenient and more strategic location is always possible with this portable version. Maintaining and taking proper care for this portable greenhouse is also not as costly and demanding than the permanent, full-sized ones.

Mini Greenhouse Ideal for Small Areas

A good greenhouse need not be always big and spacious. Although those requirements are ideal for big plant growers and commercial greenhouses, those who only have a small area for a greenhouse can also have their own by building a mini version of a greenhouse.

Gardeners who are much into planting and growing crops but have a limited garden space have an option to build a mini greenhouse. This mini greenhouse can actually be placed anywhere such as on balconies, patios, backyards, and decks as the typical size is just around 6 square feet. Though small, it also provides the same benefits that the regular greenhouses do.

Mini greenhouses are also ideal for those are just beginners in the greenhouse technology. Before venturing into building a big one, it is best to learn how greenhouse works and know the different things needed to have an ideal growing condition for the plants. And this learning process for beginners can be done by starting with mini greenhouses.

A mini greenhouse can be used to start plant growth before the cold season in a particular area. Once the weather gets better and warmer, these healthy plants and crops planted inside the greenhouse can now be transplanted outside into the garden. This will allow for early harvesting of crops. A huge selection of seeds can also be planted in the greenhouse which makes planting a lot more fun for hobbyists and gardeners.

There are a good variety of herbs and lettuce that can be grown healthily and successfully in mini-greenhouses even for the whole year. Other delectable vegetables such as Swiss chard, spinach, and kale can also be planted and grown inside the mini-greenhouse. These would make for a great bowl of salad with freshly-picked greens even during the cold season. That would be wonderful for you and your guests.

Mini greenhouses are also useful with tender perennial plants. The greenhouse can protect them from ice, snow and frost during the winter season. They can be placed in plant containers and stay healthy inside the mini structure until spring begins. Once the weather becomes friendly enough, these plants can then be again transplanted into the garden outside for a much healthier environment.

The decorative plants commonly found inside the house can be given a healthy change by placing them inside the mini greenhouse and placing them outside during the summer months. This mini structure can offer tropical plants a humid climate. Miniature greenhouses, just like the regular ones, maximize the amount of sunlight and make the most out of the heat absorbed. It also provides the needed protection of plants from rain, wind, destructive insects and other pests in the garden such as rabbits.

Since mini gardens or greenhouses can be as light as possible because of their small structure, they may be easily blown by wind or knocked over by pets and kids. Thus, it is recommended that these small gardens be placed or mounted in to a wall or garage than be a free standing structure. It is best to place them in a location where there is enough sunlight but be safe from other outside factors as well. There are also do-it-yourself greenhouse kits available in the market that include complete instructions and step-by-step guide for a beginner to build a mini greenhouse in not time. These kits can also be inexpensive and can commonly accommodate up to three shelves.

So should one really choose to have a full-sized greenhouse or just go with a miniature one? Even if a big space is available for a full-sized greenhouse, having a small one may be more practical. If the main purpose of having a greenhouse is to grow only a few plants, germinate seeds, or provide protection during the colder season, having a mini greenhouse is just fine. Also, the cost to maintain small greenhouses are significantly lower than the full-sized ones because of the several factors that need to be maintained.

Thus, it is recommended that gardeners have a greenhouse, even a mini one. This structure can prove to be a good investment and yield better results than just doing the traditional gardening.

Top Greenhouse Benefits

For people who are fond of plants, flowers, vegetations, and other ornamental plants, having their own greenhouse may be a dream come true.

A greenhouse or conservatory is a type of structure where plants are developed and grown. Usually, greenhouses are made of plastic or glass. This is to allow the natural light coming from the outside environment to permeate inside.

Because of its special condition, many people are wondering why do plants have to be cultivated inside this super special structure, wherein fact, it can be grown outside with the natural forces readily made available anytime, anywhere.

The answer to this particular issue is based on how the greenhouse really works. It is only through the understanding of its full operation that people will appreciate the advantages and environmental use of greenhouses.

Heat It Up

Putting up and maintaining a greenhouse can be a daunting task. However, the benefits that it brings not only to the environment but also to the owner of the hothouse cannot be underestimated. For one thing, greenhouses are perfect cultivating area for people who wish to grow their own vegetable farm or ornamental plants. This means that they have an all-year round supply of these items.

However, some people cannot just identify the real purpose of greenhouses because they believe that there is not so much difference between the outside environment with that of the interior condition in the greenhouse.

They say that light, water, and air are, in fact, readily made available in the natural environment. Inside the greenhouse, lights, water, and air are artificially supplied. They further contend that once the person who is in=-charge of the process has failed to do his job, chances are, the plants will die.

Hence, they insist that it would be better to cultivate the plants on its natural environment rather than locking them up in a glass-made ‘prison.”

The problem with these people is that they do not understand the main operation of the greenhouse that is why they cannot appreciate the goodness of greenhouses. They are not pleased about the benefits that greenhouses may bring.

Therefore, in order to gain the right appreciation of the purpose of greenhouses, here is a list of detailed facts about the real operation of greenhouses:

1. It uses solar energy

Like the natural environment, greenhouses make use of the solar energy as well. That is why greenhouses are made of glass or plastic to allow the natural light to pass through.

2. It converts the solar energy to heat

This is where the greenhouse benefits start. Basically, when the solar energy enters the greenhouse, the heat that goes along with the light are trapped inside the area. Once inside, the heat is distributed throughout the place. This is similar to the condition of a car that is parked in area with direct sunlight.

Have you ever observed that after you have parked your car in an open area with direct sunlight you can still felt he heat being trapped inside your car? Sam thing goes with the light and heat inside the greenhouse.

Generally, when the “electromagnetic radiation” of the sun enters the greenhouse, the things inside the structure like the soil, plants, and other notable material inside the place are being heat up.

Consequently, the materials that make up the greenhouse, like the glass or the plastic trap the hot air or the heat inside the room. Thus, it heats up both the air and the plants inside. Likewise, it also heats up the air close to the ground.

The main purpose of this particular structure of a greenhouse is to prevent “convection.” This is because through convection, heat is eliminated through the presence of fluids.

The main focus of the issue here is that this particular amount of heat should not escape the hothouse in order to proper growth to the plants.

It is for this reason that many people deem it more to cultivate their plants inside a greenhouse because with proper cultivation process as well as the regulated amount of light and heat present in the area, optimum plant growth and development is highly expected.

Indeed, just by looking at it, many people will still question the efficiency of greenhouses. But as soon as they understand the real concept behind eh operations within the area, they will soon realize that greenhouses are absolutely added features for the environment.

Window greenhouse seat board may be utilized as a pretty breakfast nook or give a place for indoor plants that takes up a lot of floor space.

The bow greenhouse window can also be a great option that comprises of more than four glass segments to imitate a rounded look. Bay greenhouse windows generally come in three segments with sides that are angled at either thirty or forty-five degrees.

Your most cost-effective and simple to build option will be a complete greenhouse bow window kit as compared to building a new window greenhouse yourself. With the kit, all you have to do is remove your existing window then enlarge the opening of the wall in accordance to the required size stipulated in the kit and just screw and nail your greenhouse window in place.

However, you should first select a size or measurement that suits your interest as well as the plants that you will be housing. More plants will mean more time is required from you in order to attend to them. Starting with a smaller greenhouse window unit can be a good idea, as you can just install another one. However when your goal is to have more open space then start bigger.

Greenhouse Supplies For A Productive Greenhouse

Ever wondered how higher altitude places can grow crops in their location? Plants need enough heat and sun’s energy to grow. However, for places that are located in the northern portion of the globe, this requirement may be difficult to attain because of the nature of their weather. Thus, farmers in these places use the greenhouse method to be able to still successfully to grow good quality crops.

A greenhouse is an enclosed structure where plants are being cultivated. This building is usually made of glass or plastic to trap the sun’s electromagnetic radiation to warm the plants and soil inside. Having a greenhouse needs proper maintenance for a more productive crop growing. Different supplies are needed by greenhouse farmers to make this happen.

Greenhouse Supplies There are different materials and equipments needed for a greenhouse planting to be effective. Here are some examples of the supplies you will need in case you are planning to build a greenhouse:

1. Heating and cooling thermostats. Since temperature is crucial to the efficiency of greenhouse structures, a thermostat is needed to be placed inside the building. The best location to mount it is near the middle of the greenhouse and at plant height. Also, it would be best if both the cooling and heating thermostats are protected from direct contact with water and sunlight.

2. Vents. Greenhouse temperature and humidity should be controlled to attain perfect growing conditions. Thus, vents are needed to be able to get in more air for proper ventilation during warm seasons, or seal out air in colder times of the year.

3. Exhaust fans. For plants to grow healthier in your greenhouse, circulation fans are needed. These fans even out the distribution of fresh air and heat inside the greenhouse.

4. Plant watering systems. Of course, aside from heat and fresh air, plants also need water to grow. You can always do the watering on your own by having water hoses long enough to reach all parts of the greenhouse. Moreover, it would be best if you just have an automatic watering system so you don’t have to worry not having to water your plants when you are out. This watering system should be placed on a shelf above the plants then connect the drippers to the circulation tubing.

5. Benches and shelving. These pieces of garden furniture are needed to be able to place more plants in lesser space. They are ideal for greenhouse owners doing gardening as a hobby. Also, a good-sized working bench is needed for potting and repotting of plants.

6. Lighting system. Having a good lighting system helps increase the speed of growth of plants as it provides plenty of light for longer periods of time.

7. Thermometers. To properly maintain the ideal conditions inside the greenhouse, you will need to monitor the different factors affecting your plants’ growth. Different thermometers are needed for you to be able to track changes occurring inside the structure. Examples of these thermometers are the regular thermometer, humidity gauge, soil thermometer and the light intensity meter.

8. Ground cover. Since weeds are known to grow anywhere, it is best to protect your soil from these weeds that carry pests and diseases to plants. To do this, you can have a ground cover as a floor to your greenhouse or cover it with soil, sand, brick and gravel.

9. Cycle timers. To be able to automate the equipments you use in your greenhouse, you can also put a cycle timer which can accurately cycle the equipments on and off time. This is ideal for ventilation controls, irrigation, and misting. With this timer, you do not have to worry going in and out of your greenhouse to turn the machines on and off.

Greenhouse Supplies For Every Glass House

More and more people are maintaining a greenhouse in their own yards. Most have found it a fulfilling endeavor, not just to grow plants, but to grow plants well. Thus if this interests you, then it is best to learn the basics of a greenhouse.

What Is a Greenhouse?

The greenhouse serves as the home for young and tender plants, especially those grown out of their normal season. This is mainly designed to create a proper environment for the plant and for cultivation of the same.

It is usually made with plastic or glass-paned sloping roof and walls. This way, the temperature, light and even moisture can be easily controlled to give a balanced condition encouraging to the plants.

The greenhouse is best suited to grow plants of all kinds. The usual varieties are cacti, orchids and citrus trees. This is also a very ideal venue to implement plant research.

Ideally, the natural sunlight is sufficient to supply the requirements of plants, especially in temperate regions. However, when winter comes it is necessary to supply the plants with heat and light to encourage growth. The heat usually comes from steam or hot-air circulating system.

During the summer, the panes would be covered to reduce the light intensity. The structure of the greenhouse will allow heat to be easily reduced. This is done by opening the ventilators or whitewashing the panes.

Humidity is maintained by the water supplied in the soils. When the greenhouse needs greater humidity, the floors are usually sprayed with water. For pot-grown plants, like the orchids, they are set on racks with moistened residues.

There are many aspects that make a productive greenhouse. These generally depend on the supplies installed in the greenhouse. To know what these supplies are, just read on.

What Are the Important Greenhouse Supplies?

To have a really successful greenhouse, it is important to have the proper supplies and accessories to put in it. Listed below are several important greenhouse supplies.

1. Ventilation

This is the most important supply you can not miss out on your greenhouse. It serves to purposes, to provide carbon dioxide to plants and to cool the greenhouse. Without this, the greenhouse might just be simply your furnace.

The greenhouse is really storing the heat coming from the sun during the day, creating a warmer environment inside the greenhouse compared to the outside. Thus the ventilation fan system will be helpful in bringing in fresh and cooler air inside.

2. Heating System

The heating source is important too, especially during the nighttime and for the cold seasons to come. Generally, the heat supplied by the sun is stored by the greenhouse. At night, the heating systems will serve as the heat source.

This can be fueled by wood, gas, oil or even electricity. The choice simply depends on whatever type of fuel can be available in the locality as well the costs.

Some make use of electric heaters for smaller greenhouses. This should be treated with extra caution. It is not supposed to be exposed or be in contact to water to avoid any electric shock.

3. Greenhouse Thermometers

It is not sufficient that you provide temperature in the greenhouse. You have to be able to control and maintain the proper temperature. The only way you can do this is to get the min/max thermometer. This records the high and low temperature of the greenhouse.

What is at stake is the valuable data that can help you determine if the heating or cooling equipment is working correctly.

4. Fog System and Watering System

Mist and fog systems are useful in any serious greenhouse. It helps in maintaining the humidity level. A good amount of humidity can also help reduce the need for water supply.

When it comes to watering the plants, it will have to depend on the type of the plant. The regular wand can be used on the average grown plants. The drip system is best for watering larger plants. This is also a good way to save on water.

For seedlings, it is ideal to use a watering system with small sprinklers, or even misting systems. Using the regular hose or wand will simply disturb the soil.

5. Lighting

Lighting is also very important for growing plants. This will serve as the artificial sun, especially when the season does not give much heat, light and sun.

6. Shading

Shades come in handy during the hot summer. They block a certain part of the rays of the sun from entering the greenhouse. This is to avoid too much heat and sunlight on a dry season. The shade is also very helpful to some plants that grow best when screened from the direct sun.

7. Flooring and Benches

The flooring details will be for the benefit of the greenhouse owner. It can be aesthetic as it polishes the image and ambience of the greenhouse. It can also be functional. It is best to use non-skid surface so there will be not much worry during watering time. It should be easy to clean and must be able to endure the moisture in the environment.

Benches can also provide comfort. When attending to the plants, it would not hurt to do it while sitting. It is also a good place to observe and enjoy the fruits of your labor. This can also serve shading purposes to plants located beneath or just behind it.

With these important details at hand, you can easily come up with a master plan to get that perfect greenhouse for your plants.

How To Build A Greenhouse Structure?

Having a garden is not just about planting crops and harvesting it. There is a lot of work to be done to protect it from disease, pests and the weather. Since these areas are usually big and require a lot of manpower, scientists have come up with a better idea.

This plan is to grow crops in a controlled environment which makes it easy to grow crops all throughout the year. This structure which can be big or small depending on the open space in the farm is known as the greenhouse.

A greenhouse is an enclosed building that is usually made up of metal, wood and glass. These structures are designed so that the farmer can grow vegetables, flowers and fruits. The person can buy one and have it assembled in the farm or have it custom made according to certain specifications.

This new method has better results than doing farming the non-organic way such as the use of sewage, irradiation, pesticides and herbicides. This is only after tests have shown that this is a health risk that does more harm than good.

A very good example which has shown that this approach is effective is the use of hydroponics farming. This technique doesn’t require the use of soil but rather water to make the plant grow. In one experiment, scientists were able to produce more tomatoes using water than it was using soil.

Since then, other ways of doing hydroponics have been done and this has helped the productivity of the farmers.

More farmers rely on free standing greenhouses. Before these can be set up in the farmland, a good location must be determined that should provide adequate sunlight and wind to help the plants grow.

The most important thing that keeps the greenhouse standing is the frame. Developers have made versions using wood, metal, aluminum and plastic. The farmer can use any of these or have one that is a combination of any of these materials. This will depend on the budget of the farmer and the type of weather conditions there is in the area.

Plants grow because of two things. The first is the nutrients that are given to it. The second is sunlight. This makes it important for the farmer to choose the right panels.

Traditional greenhouses use glass but there are many problems when these are used as panels. Since it doesn’t protect the crops from the sun and merely lets it in, too much heat can kill the plants.

When there is a hurricane or a hailstorm, rocks and other things in most cases break the glass. This will cost a lot of money on the part of farmer to replace.

In order for the farmer to make money in selling crops than paying for repairs, designers have made panels using other things such as plastic, film and Plexiglas. This is a remarkable improvement since these are shatterproof and are able to stand severe weather conditions.

These also allow only 75% of ultraviolet light to enter the greenhouse which is the sufficient amount needed to help the plants grow.

The climate is changing and that is something that people cannot change. The effects of El Niño and La Niña have made the weather worse than the year before and this is a challenge that farmers must face.

Another thing that makes up the greenhouse is the equipment needed to keep it running. Farming in a cold climate can be difficult and since plants need warmth, a heater should also be installed.

Heaters come in big and small sizes. This can be powered by electricity, using propane gas, oil and other non-renewable resources. This device gives farmers the means to meet the demands of the people especially during the winter.

Farms have also changed thanks to technology. People don’t have to till the land anymore using rakes. Greenhouses can have timers which release water mixed with nutrients at certain times of the day helping the plants grow.

Though it is quite expensive to build a greenhouse, by selecting the proper structure, the farmer can be sure that come harvest time, there will be enough crops to sell to the market and money can be made.

Greenhouses: Gardening All Year Long

Gardening enthusiasts in the more interesting temperate climates and any place where there are four seasons are faced with great benefits as well as challenges. Because of the four seasons, gardeners are blessed with huge plant varieties conducive for planting on one or two of the seasons. In the period of a year, they are given an opportunity to plant varieties that must grow in cooler climates, and take advantage of the sunny summer to plant those that would require more exposure to the sun.

However, the seasonality of plant varieties may pose challenges to those who would rather grow plants continuously, regardless of season. This is especially true for flower and fruit varieties that require continuous sunlight for an entire year, for example, or fruit and vegetable perennials that do not bear fruit and instead shrivel up in the winter.

The response to these challenges is the creation of greenhouses or greenhouse facilities. A greenhouse is a structure made of glass or plastic that stores up the sun’s rays in order to simulate the temperatures in the spring all year long inside. By storing up heat inside a greenhouse, it allows individuals to grow plants continuously even while winter rages hard outside it. Greenhouses also go by the name glasshouses or hothouses.

The glass or plastic used in the construction of greenhouses are specially designed to have transmission qualities that will allow for the sun’s ultraviolet rays to be stored inside the greenhouse facility, providing a warm atmosphere inside, and in effect, warming the plants and the soil. A greenhouse leaves little or no openings through which the air heated by the stored sunlight can escape; leaving a small window or hatch open in a greenhouse will lead to a drastic drop in temperatures.

The general idea of a greenhouse is to protect temperature and climate sensitive plants from extreme shifts in temperature—either too hot or too cold. Maintaining a greenhouse has its own share of toil. Unlike the normal outdoor environment, which may be left to its own devices to some extent as nature creates some degree of balance, a greenhouse must be placed under strict regulation. Inside the greenhouse is a controlled environment that must simulate the outdoors without overdoing it.

For a start, it must regulate heat and humidity inside the facility. Other factors to be considered are irrigation of the plants (and sufficiency of the water available to them), light exposure, and the presence of pests and diseases must be put into great consideration. Moreover, due to the fact that the spring outdoors is sealed into a single facility, natural activities like pollination must be simulated by the introduction of species that will help make this possible. Bumblebees are the most popular option for pollinators in greenhouses.

It is recommended that greenhouses be built in the southeast portion of the property. It is in this way that the minimal sunlight available during the winter will be maximized by the greenhouse. Moreover, the house can serve to protect the greenhouse from strong winter blizzards coming in from the north. Greenhouses may be built attached to a house, or as stand-alone structures. The latter option provides more growing room for the greenhouse facility.

While it may seem that there is too much to do in order to simply start a greenhouse, gardening enthusiasts will be more than willing to vouch for greenhouses, especially if gardening is a hobby. Gardening affords even the busiest of folks to tend to their plants when they are available. With a greenhouse, the constraints of day and night, and even the seasons, are put in the backseat. Greenhouses provide the option of tending to gardens even at night because lighting and heat is consistently present inside the structure.

Moreover, it gives gardeners the ability to plant exotic flowers and fruits that are usually grown in warmer tropical areas as they are able to control light exposure and heat inside the greenhouse.

Greenhouses may even provide profit-making possibilities for gardeners. With potted plants for indoor growing and flowers growing in demand, greenhouse owners are given opportunities to sell what they grow inside their greenhouses to buffer whatever maintenance costs they incur along the way.

In the higher-latitude territories, greenhouses carry the important task of growing fresh produce in areas where the climates are harsh and cruel on plants. This is one of the biggest reasons for huge greenhouse facilities that house vegetables and fruits more than flowers and exotic foliage.

At the end of the day, greenhouses allow for the creation of a miniaturized and highly controlled natural environment to suit gardening needs. Its growing potential to provide for fresh produce in territories even with the instability of global climate proves to be a benefit that may be explored in the future.

Create a Warm and Suitable Environment for Growth with Greenhouse Plastic

Greenhouse plastic is mainly responsible for maintaining a hothouse effect within a greenhouse. Greenhouse plastic creates a warm and suitable growing environment that allows various types of plants to cultivate beautifully. It creates an enclosure that protects plants from the harmful ultraviolet rays of the sun while taking advantage of its natural warmth and light. The filtered environment produced by greenhouse plastic makes it possible for garden enthusiasts to grow luscious plants like vegetables and flowers in the cold dead of winter.

Greenhouse plastic is explicitly designed to resist wear and tear unlike conventional construction plastic that cannot filter ultraviolet rays from the sun. Greenhouse plastic is durable due to its knitted design that allows it to be cut and sized to meet the required length for a structure without fraying, ripping or tearing. The material can easily be framed around any greenhouse opening like a vent, door or windows.

Greenhouse plastic is the preferred covering of most garden enthusiasts compared to other types of greenhouse covering. At the same time costs are greatly reduced when greenhouse plastic is used since it lightweight and does not require heavy-duty structural framing. The diffusion of light into a structure constructed of greenhouse plastic is as good as that of a glass greenhouse.

Types of Greenhouse Plastic

Greenhouse plastic films are generally made of three types of plastics namely, PVC or polyvinyl chloride, PE or polyethylene and copolymers. Although, there are other types of plastic used these three are most widely used among all.

Polyethylene greenhouse plastic is available in two types, the utility grade and the commercial grade greenhouse plastic. Utility grade polyethylene greenhouse plastic is sold at local hardware stores and generally stays in good condition for practically a year. Commercial grade polyethylene greenhouse plastic last longer that utility grade PE up to eighteen months and is treated with ultraviolet inhibitors that filter out ultraviolet rays.

Copolymers are more durable and last up to three years. Innovative additives introduced into greenhouse plastic enable it to mimic the same effects of a glass greenhouse at considerably reduced costs. Polyvinyl chloride is more expensive compared to polyethylene however this type of greenhouse plastic can last up to five years. However PVC greenhouse plastic requires regular washing to prevent dust buildup from the air. It is also sold in smaller sheets of four feet by six feet wide.

How to Attach Greenhouse Plastic to Frame

Once the frame has been built it is time to put on the greenhouse plastic film to enclose the entire structure. The plastic film can either be made of polyethylene, copolymers or polyvinyl chloride depending the preference of the owner. But as much as possible choose a greenhouse plastic that is resistant to ultraviolet rays in order to make the most of the structure. Before laying the greenhouse plastic covering on the frame it is important to mask the joints of the frames with several rounds of tape or a rubber material to prevent it from puncturing the covering.

The greenhouse plastic film can be secured in place using a staple gun. A more rigid construction using 1” by 2” wood strips and wood screws can also be used to secure the greenhouse plastic film in place. The wood strips are attached to the frame so that the greenhouse plastic film does not come in direct contact with the frame.

A popular technique used by nurseries is a double-walled construction for better insulation within the structure that adds up to considerable energy savings. Two sheets of plastic are layered and framed leaving a small amount of space in between about five to eight inches wide. Air is introduced into the framed plastics that produce a dead air zone, which can efficiently insulate the entire greenhouse. Various tapes like poly patching tape and batten tape can be used to secure greenhouse plastic into place.

Poly patching tape is constructed from UV protected acrylic along with the adhesive to protect the greenhouse plastic from weakening on contact with it. This type of tape can be used to patch holes and rips that may happen to the plastic film. Its excellent holding strength and wide tape make an ideal for securing the plastic film to the frame of the greenhouse. On the other hand batten tape can be fastened the plastic film using staples or tacks to the greenhouse structure. It is also made of heavy gauge vinyl that is also UV protected.

How To Find The Easiest To Build A Greenhouse For Sale

Building a greenhouse is like building a house. You should have a well-designed plan and several things need to be taken into consideration. There are different types of home greenhouses but your choice should depend on the growing area, architecture, location and costs. Most importantly, the greenhouse that you will be building should, of course, serve its purpose of maintaining a proper environment for plants to grow.

As mentioned, there are several things that need to be considered when putting up a greenhouse. To give you some tips, here are the things to be included in the planning stage:

- Location. First thing to note in building a greenhouse is its location. The best location for a greenhouse is a place where it will get maximum sunlight. Morning sunlight is best for plants because it makes them start processing early which will result to maximized growth.

Thus, the best location is on the east side where it gets maximum morning sunlight especially from November to February. North of buildings or any major structure is the last location to be considered as it only provides little light. Also, it is best to make sure that the trees nearby the chosen location will still allow enough sunlight to reach the greenhouse.

Other things to be considered when choosing location are good drainage, location of sources of water, electricity and heat. The location should also be convenient for the owner or the caretaker as well as to the utilities.

- Greenhouse type. In general, a home greenhouse can be any of these two types – a free-standing structure or one that is attached to your house or garage. Attached greenhouses also have different kinds. One example of an attached greenhouse is the lean-to. This is a half greenhouse attached directly to one side of a house or building with doorway, if possible. This type is close to sources of heat, water and electricity and is the least expensive. However, this kind of structure also has some limitations on space, ventilation, and sunlight.

Another attached greenhouse variation is the even-span. This kind of structure has one gable end connected to a building. It provides more usable space and allows for better air flow to maintain temperature. It is also the most costly, though, among the attached ones.

The third type of an attached greenhouse is the window-mounted. This type can be attached on the east or south side of the house or building. This is a glass enclosure that extends a foot or so, which gives enough space for growing a few plants at low cost.

Freestanding greenhouses are separate structures that are not limited to a small space. Since it is set apart from an existing structure or building, it should have its own water and electricity sources as well as heating system.

When choosing the preferred structure, make sure that enough space for benches, storage, as well as future expansion is considered. The University of Maryland Cooperative Extension Service suggests a minimum area of 6 feet by 12 feet for a free-standing or even-span greenhouse.

- Structural Materials. Your greenhouse should also have a good structural foundation to withstand extreme weather conditions. There are several options for a frame and framing materials to choose from. Do-it-yourself greenhouse plans commonly use wood or metal pipes as their structural material. There are different kinds of frames available which range from simple to complex designs. Some examples of frames are Quonset, gothic, rigid-frame, post and rafter, and A-frame.

Another material to be considered is the covering for your greenhouse. Your choice of frame and covering should correctly match. Some factors to be considered to choose a good covering is its ability to trap the most amount of heat inside, as well as its life span. The different choices for greenhouse covering include regular glass, fiberglass, double-wall plastic, and film plastic.

- Foundations and flooring. Glass frames and the double-wall plastic need a permanent foundation and the plan should be provided by the manufacturers of the frame. It is also recommended for the greenhouse to be elevated a little to have enough space for water to flow. Thus, permanent flooring is not advisable as the soil may stay wet and make the floor slippery. A walkway made of gravel, concrete or stone is advised for easy access to the all the plants.

- Environmental systems. Once you now have a good plan for the structure of your home greenhouse, the next thing to consider is its proper maintenance. Aside from sunlight and heat, different elements are important to maintain the ideal growing condition for plants. These environmental systems that should be included in greenhouse planning are heating, air circulation, ventilation, cooling, controllers and automation, water and lighting systems.

Building a greenhouse can prove to be demanding and challenging. Complete knowledge about greenhouse is needed for you to be able to build a productive structure. A considerable amount of time is needed to make a good plan which should cover all aspects. It pays to learn and scout for different options before making your final decision.

Choose The Right Greenhouse Panels

The material of your greenhouse is a very significant factor in terms of heat transfer and the heat it can retain, durability, and the cost in keeping maintaining a warm greenhouse temperature all throughout the winter months.

There are many materials that are used as greenhouse panels that are available in the market that you can choose from, such as glass, polythene plastic, fiberglass, and polycarbonate are a few of the common and most popular materials today.

Each material type works well as each also has its individual strong and weak points. Certainly, some panels suit better the budget of the hobbyist’s.

When deciding on a panel for your hobby greenhouse you have to consider the following:

• The amount of light that can be transmitted.

• The toughness of climate in your area (some can be very windy).

• Easy installation.

• Easy to maintain.

• Decrease light transfer as the panel ages.

• How much heat it can hold.

• Durability and estimated life of the panel until the need of replacement.

• Price.

• Endurance to heavy rain and strong wind; tearing or breakage.

• Weight.

• Flammability.

Fiberglass, glass and polycarbonates, are excellent choices for one who is into a greenhouse hobby. Plastic panels are commonly used in commercial large greenhouses although they are not very durable and entail frequent replacing.

Glass, the traditional greenhouse paneling has a very pleasing appearance, can be easily and reasonably maintained and has high level of permanency. When one is really concerned about the look of the greenhouse, then glass can be a good choice for paneling.

Glass permits large amounts of light to pass through, in fact amongst all paneling, it is glass that can transmit light effectively, and however, it can break easily.

If you choose to use glass, just make certain that your greenhouse framing and foundation should really be strong, as glass can be heavy. An aluminum framing is best when using glass, although it can be expensive to keep the greenhouse warm as aluminum absorbs the cold during winter.

The drawback of using glass for paneling is that glass is a breakable material, initially very expensive to construct, needs a very strong framing and foundation to support its rigidity and heaviness.

Polycarbonate, although not as attractive as glass, yet it is much more durable. It likewise can not let in as compared to glass; however sunlight that passes through this material is less slightly concentrated so that plants will not catch the intense sunlight and heat that a glass greenhouses permits. To reduce the cost of heating, double or even triple polycarbonate paneling sheets can work excellently for retaining in the heat.

Fiberglass is a strong, lightweight and essentially hail-proof paneling material. However, you should use good quality fiberglass since poor grades can discolor as well reduce penetration of light overtime. Likewise, you need to use clear and transparent types only. Tedlar-coated quality fiberglass can lasts up to 20 years.

The resin coating that the glass fibers have eventually will wear off, permitting dirt to be deposited in the fibers. Therefore, after about 15 years, there is a need to put on a new resin coating. The penetration of light can be initially compared to glass, although as it ages, it will considerably drop off especially when you use poor quality fiberglass. Double-layered rigid plastic paneling sheets of polycarbonate or acrylic are available for heat-saving and long-life, covers.

These types of paneling have two coatings of rigid or bendable plastic whish are divided by webs. This double-layer type of material maintains more heat, therefore on can save energy of up to 30 percent.

The acrylic paneling is a long lasting, does not discolor; the polycarbonate generally turns yellow faster, yet typically is shielded by a “UV-inhibitor” covering on the surface that is exposed to sun and rain. Both paneling do carry warranties on light transmission characteristics for up to10 years. And both are ideal for curved surfaces, but polycarbonate paneling is the most bendable paneling material.

Just keep in mind that the best panel material for your greenhouse is the one that suits your needs and style and of course, your budget. Just purchase the best one you can afford.

Greenhouse Misting Systems

Greenhouses have become important tools in plant cultivation. They provide much needed growing rooms for places which are not very conducive for the development of certain plants. They allow the cultivation of plants in places which could grow these plants normally. Since it is easy to find a greenhouse for sale and put it together with a kit, more and more inovations are being used to keep the growing season as long as possible

There are many factors which can affect the development of plants inside a greenhouse. The proper balance of air circulation, ventilation, humidity, shading and heating will provide the plants with an optimum environment.

Greenhouse Misting

Other factors will such as ventilation and shading, are important for prevention of overheating in the greenhouse. However, proper misting or the control of humidity is the main factor which maintains a comfortable environment for the cultivation of plants. Evaporation uses up heat when it turns water from liquid into a gas. When the venting process is done, much needed moisture is lost from the greenhouse because it escapes into the air. Misting is one of the ways to replace the lost moisture inside the greenhouse.

The amount of moisture which is needed to be maintained by the greenhouse is dependent on several factors such as the amount of shading and ventilation that is provided, the status of the local climate and the fluctuations in the daily weather. The rule of thumb is that for each 10 square-ft of area, there must be 1-2 gallons/hour of moisture. A misting system will effectively distribute moisture evenly to all the parts of the greenhouse. A good misting system can disperse water in a fine mist, this will prevent the plants from being soaked.

Misting systems reduce temperatures by as much as twenty-five degrees F which is about 14 degrees Celsius.

Here are some facts about misting systems

-Misting systems can be used to disperse water in an ultra fine mist or a very coarse spray. The size of the droplets can depend on the nozzle type, the spacing of the nozzle and the operating pressure.

-Misting systems are used for many different kinds of applications aside from its normal greenhouse chores. They can be used from dust suppression, controlling static electricity control and concrete curing.

-Misting systems utilize pumps which are designed for intermittent or continuous duty. Intermittent pumps are designed to sprinkle water for five minutes and rest for a minute in between misting.

-Misting systems now come with electronic timers which can be programmed to mist 1-14 times a day with each misting ranging from 1 minute to 24 minutes. Other systems can be programmed to mist in shorter durations but more often.

-Nozzles are made from brass or plastic materials. The brass nozzles can be easily affected by minerals that abound in the water supply. The plastic nozzles can tolerate these minerals and can actually repel lime and other deposits.

-The amount of water which is needed to maximize the efficiency of the misting system can be calculated by multiplying the rate of the nozzle flow per minute by the number of nozzles in the system and the result will then be multiplied again by the minutes that the misting system will be in operation each day. This result will be a good estimate of how much water is needed by the system.

-Most misting systems today offer pumps which are almost noise-free. They will not affect the plants and especially the people near the greenhouse.

-Misting systems can be supplemented by an evaporative cooler. They work very well in dry climates (where humidity is below 50%). The air is cooled by around 10-20 degrees by the water which is evaporated because they are drawn through the cooler and then into the greenhouse. Too much humidity can be a problem and this is why people should water the plant only when they need it.

-The use of tools which can measure humidity can also be very helpful for greenhouse enthusiasts.

There are other factors that need to be considered in greenhouse plant cultivation. Misting is just one of them. Misting provides the plants with much needed cooling for the plants. There are many tools out there that are available for greenhouse plant cultivations which can immensely increase the quality of their greenhouses especially in terms of misting. A cultivator just needs to find out what kind of misting system should be employed for his plants.

Greenhouses Used By Farmers

The ancient people of Egypt did farming using a good irrigation system and proper sunlight to make the crops grow. This practice still continues today which has served as the backbone of the agricultural industry.

Since the weather, insects and diseases threaten the crops throughout the year; this has prompted scientists and farmers to use of fertilizers, pesticides and herbicides to sustain crop production.

Recent studies have shown that this does more harm than good since the ingredients for these products are hazardous to health. This has changed again the approach used by farmers and scientist who want to go back to organic farming.

To control crop production against the weather, greenhouses have been erected. This provides a controlled environment to grow the plants all throughout the year.

Greenhouses are usually built using wood and metal while the panels are made of glass. Since this isn’t sturdy enough to withstand the weather, termites and rust, manufacturers have come up with many models using different materials.

The frames of the greenhouses can now be made of aluminum and plastic which is rust and termite resistant. Frames on the other hand can be made of plastic or film which has been proven to be stronger than glass during heavy snow and hail storms.

It is also scratch proof and will not break even if a rock is thrown at it. This has also proven to allow only 70% to 75% of ultraviolet rays from entering the greenhouse which is the right amount of sunlight needed for plants to grow.

Each of these depends on the specifications of the farmer and how big the area is. There are freestanding versions and there are those that can be custom made. The person has to assess the area before making the decision of what kind of greenhouse is ideal.

Greenhouse manufacturers do not only make the shelter for the plants. It also provides instruments and machines to ensure plant growth. This will all depend on how often it is used, the types of plants and the weather where it will be put up.

Farmers who live in cold climates need heaters to keep the plants warm during the autumn and winter months. This can be bought in different sizes that cater to the needs of the individual.

Manufacturers can also provide timers that can release water at different times of the day to give plants the proper nutrients for growth.

There are many ways to do farming and manufacturers who have been in the business for years can give good advice. A very popular technique used in the United States and in Europe is called Hydroponics.

This uses water instead of soil for plant growth. Manufacturers of these greenhouses can provide the necessary tools and machines that will make this process work. There are many ways that this can be done and those who are new to this technique can learn from these professionals.

A good thing about this technique is that farmers are able to product 4 to 6 times more than the traditional method. It also helps these people avoid the usual problems with soil such as weeds, diseases and pests.

Greenhouses do not have to be expensive. The farmer just has to check what is needed then work with the manufacturer within a certain budget. Some manufacturers can even offer better prices when these are ordered online with free delivery.

There are organizations that farmers and hobbyists can reach to get the right greenhouse. Some of these people also join agricultural conventions and other events to promote the use of greenhouses.

Manufacturers not only make or deliver the parts to assemble the greenhouse. These professionals are also there to assemble it since these are heavy and sometimes delicate which is costly for the farmer to replace.

Farming has not changed that much through the years. The basic things needed for plant growth are still water, nutrients and the right environment. The greenhouse allows the farmer to grow crops not only once a year but all throughout even during the hottest and coldest climates.

By working with the manufacturers of these structures, farmers will also be able to produce more yields which are good for business and the public will always have fruits, vegetables and flowers.

More Greenhouse Lighting Tips

If you are one of those few people who are in love with nature, then, having a greenhouse garden at your background is an incredible idea. With a greenhouse kit, anyone can put together a great greenhouse In fact, according to some statistical reports, 80% of the 100 people that owned greenhouses in the United States were nature lovers, while the remaining 20% said it was purely for commercial gains.

Built specially for plant cultivation, greenhouses or hothouses are specially designed to suit the needs of every plant lover. It is a sanctuary where people and plants can bond together and enjoy each other as they fill the world with lush flora and abundant greens.

In as much as greenhouses are designed to provide the perfect environment for any kind of plant, there are some cases wherein the viability of the equipment is still dependent on the owner of the greenhouse or to those who manage the area.

In this sense, it is important for every greenhouse owner to see to it that the needs of the conservatory are being met.

The Greenhouse Setting

Technically, the main concept of a greenhouse is that the plants are placed in a space confined in a specially designed structure. Since the plants were not cultivated in an open area, it is extremely important for the owner to provide the necessary requirements that the plants have.

One should keep in mind that the plants are placed in a secured place; hence, it is the responsibility of the greenhouse owner or the one who manages the place to provide the needs similar to that of the ones being enjoyed by the plants in the exterior environment.

Greenhouse Lighting

One of the most important necessities of every plant in order to manufacture its own food is the light. You have probably learned from your grade school science teacher that plants need light in order to produce its own food, along with the other factors such as water and air.

With respect to the conditions inside the greenhouse, it is important for the plants to receive adequate amount of light in order to develop and grow on its maximum state. This is especially useful during winter, where no amount of natural light can be produced.

Hence, it is extremely significant to provide some artificial lights in order to supply the lighting needs of every plant inside the hothouse.

Today, there are various kinds of lighting features that are built to suit the individual needs of the plants being cultivated in greenhouses. Choosing a specific greenhouse light can be very tricky, especially if you are not yet familiar with it.

Hence, it is so important to consider some factors when buying a greenhouse light. Here is the list that you can use when buying the items:

1. Type of greenhouse

Before buying a greenhouse light, try to consider first the kind of greenhouse that you have. Is it a commercial greenhouse or a personal one?

Knowing what type of greenhouse that you have could easily teach you what kind of light to choose. For instance, if you have a commercial greenhouse, it is best that you buy a light that is created to endure humid, adverse conditions that are commonly found in commercial conservatories.

2. Length of use

It does not necessarily mean that when you buy lighting fixtures you will absolutely use them 24 hours a day. The duration of light use in greenhouses are based on “photoperiods.” This means that the period, in which, the light will be used may vary. For example, one may use lighting for a “12-hour photoperiod.” This means that within 24 hours cycle, lighting will be used for 12 hours and 12 hours with no light at all.

Hence, it is important to buy a light that will provide the necessary benefits even if it will take longer hours of use.

3. Purpose

Buy a light that will focus more on your desired results. For instance, if you want to motivate the growth of your flowering plants like the orchids, it is best to buy a light that will put more weight on the “spectrum colors” like the red, blue and the “far-red wavelengths.”

Besides, the colors of the light have notable effects on the plant growth. This means that not all light can actually produce the desired results.

4. Electrical efficiency

Even if lighting can provide most of what your greenhouse needs, it is also important to take note of the efficiency of the product. This means that you should better opt for those lighting products that provide optimum effect without having to compromise the amount of energy that they consume.

It would be better to buy lights that are efficient but can still conserve as little energy as possible.

5. Heat

Do remember that lighting should only be used where it is needed. This goes to show that any light that emits more than what it is needed for is actually worthless. Simply put, a light that emits more heat as it releases light is of no use. Too much heat on plants will trigger its death. For example, it is not a good idea to buy an incandescent bulb because it gives out too much heat.

Indeed, lighting is such an important factor in a plant’s development. Hence, it is very important to consider the kinds of light to be used in your greenhouse in order to ensure the quality of plant growth that you want to achieve.

Greenhouse Kits Explained

What Is a Greenhouse Kit?

Greenhouses are used for cultivating different kinds of plants. From fruits, vegetables, flowers and other ornamental plants, these are now grown in greenhouses. A greenhouse uses the concept utilized by Earth to maintain heat inside. It is a structure which uses electromagnetic radiation to be able to capture heat and keep it inside to make the environment more conducive for plant cultivation.

Greenhouse Kits are usually made up of plastic or glass materials. It heats up the plants by acting like a blanket for them. The warmed air is retained by the walls and the roof of the green house.

The plastic or glass used in greenhouse construction is specifically made to trap the energy into the greenhouse. The greenhouse prevents convection and thus prevents the heated air from escaping outside.

There are several requirements in effective plant cultivation in greenhouses as compared to plant cultivation outdoors. Special care is needed to be able to prevent pests and diseases from infesting the plants. The greenhouse’s temperature should also be monitored so as to give the plants the optimum conducive environment for their growth.

In this light, the right greenhouse supplies should be availed by interested cultivators. There are a lot of greenhouse kits available out there for people who would want to put up their own greenhouses for commercial plant cultivation or as a plain hobby.

A Greenhouse Kit: Economy for Both Amateur and Professional Gardeners

A greenhouse kit is a great way for both amateur and professional gardeners to enjoy year round gardening. Greenhouses for sale that you put together are very common. Greenhouses are garden structures designed to cultivate plants by harnessing the heat generated by the electromagnetic radiation coming from the sun. The heat is retained within the structure’s walls and roof to heat the plants and the soil within it.

Greenhouses can be used to effectively farm various plants such as flowers, fruits and even vegetables within its controlled environment wherein humidity, condensation and light are the key factors that contribute to its effectiveness. These structures are generally freestanding however other designs may also be joined to the house or built in a lean-to manner.

The size of greenhouses also varies depending on the purpose of the structure. Miniature greenhouses may simply be a window extension that can be used for growing herbs while massive greenhouses can be as wide as block and usually for business purposes.

In previous years, greenhouses were generally custom-built with a huge price tag attached to them. But today greenhouse kits have become readily available and affordable for the enjoyment of every amateur or professional gardener.

Things to Consider When Before Buying a Greenhouse Kit

Ready-to-build greenhouse kits have become quite popular as they offer an extensive selection of sizes and styles. These kits give a gardener the opportunity to adapt the structure to the design of their garden in order to fit and match. Before choosing and buying a greenhouse kit, it is important to consider a number of factors in order to be able to select the ideal kit.

It is important to take into account the type of plants to be grown within the structure as well as the type of gardening to be done along with the climate of the region where the greenhouse structure would be assembled.

For instance, a gardener interested in planting within a wintry climate should consider a greenhouse kit that has a double-walled area that is securely sealed. On the other hand, a gardener that wants to start seed planting should think about getting a greenhouse kit constructed with plastic frames and sidings.

Greenhouse Kit Details

Greenhouse kits come in various sizes ranging from 6 feet by 8 feet to 16 feet by 24 feet. The styles of greenhouse kits are also varied to represent classic conservatory designs that are marked by the typical gable roof with straight eaves. Victorian style greenhouse kits are also available. This style features either a rustic look with wooden frames or a gothic vaulted roof with curved eaves.

In most cases, the frame of greenhouse kits are usually made either of plastic, aluminum, galvanized steel, cedar or redwood. However, many favor plastic greenhouse kits as they are more affordable and provide the smallest amount of heat loss compared to other kits.

In traditional custom-made greenhouses the siding is built with either a double or triple wall of glass in order to keep the heat trapped within. Greenhouse kits use mainly plastics that provide excellent insulation and at the same time unbreakable. Commonly plastics used are polyethylene, polycarbonate and fiberglass.

Greenhouse kits are generally easy to put together as the parts are already pre-drilled and pre-cut. There are even greenhouse kits available that use a snap-together frame for easier assembly. A reasonably priced greenhouse kit may possibly include aluminum or galvanized steel frames, a see-through plastic cover with a door incorporated into it.

The door may either be a zippered side-flap or a roll-up depending on the design of the greenhouse kit. The typical ceiling height of a greenhouse kit is about 8 feet to allow for headroom of the gardener. There are times however when a greenhouse kit may not include certain items such as shelving, flooring or anchor system.

Although some greenhouse kits provide the owner with information on how to lay down a foundation for the hothouse using any of these weather resistant materials like wood, poured concrete or even concrete patio stones. The purpose of a level-flooring surface is to provide good drainage as well as hinder wind damage for the structure. Reasonably priced floor-framing kits are readily available at gardening stores that also sell greenhouse kits.

Greenhouse Heaters 101

Temperature changes several times a day. And during the night, it could really drop to a low level that may not be healthy for plants. Thus, to keep the temperature at a suitable level for a successful plant growth, greenhouse heaters are needed. In choosing the right greenhouse heater, you must take into consideration not only the capability of having a good temperature during cold, winter nights, but also the costs to be incurred in installing and running it.

Kinds of Greenhouse Heaters - Electric heaters. This kind of heater is most suitable for smaller greenhouse structures. Electric heaters can efficiently maintain specified temperature levels. These do not produce any fumes and there is no further need for ventilation when these heaters are being used.

- Gas heaters. Since these heaters are fuelled either by natural gas or bottled ones, they can be less efficient that the electric heaters. Their waste products due to combustion are discharged into the greenhouse and ventilation is required when they are in use. Also, these heaters should be placed in a safe location and need constant monitoring and replacement.

- Paraffin heaters. This kind of heaters is the most basic among the three. Paraffin heaters need constant refilling and wick-trimming. They also need fuel to run, thus, fumes are again discharged into the greenhouse and would need ventilation. However, paraffin heaters can reduce the risk of frost damage and act as emergency standby.

Heater Mounting - Hanging. These heaters are mounted directly to the ceiling or hung from it. It is advantageous to use because of less floor space consumed. They should just be hung high enough as to not be an obstruction.

- Wall. This type of heaters is mounted directly to the wall and vent towards the outside of the greenhouse. No floor space is required but the area in front of them should be clear.

- Floor. This type is not mounted as they have their own stand and can be placed anywhere on the floor of the greenhouse. That is the disadvantage of this type because it occupies a lot of space.

Heater Combustion - Open. This kind of heater uses air inside the greenhouse for combustion. As long as the air does not have contaminants in it, this will work just fine. Flammable liquids should not be placed near an open combustion heater, though, because its burner is not sealed.

- Separated. A gas heater uses this kind of combustion mechanism wherein it uses the air outside the greenhouse for combustion. Its burner is also sealed to trap all the air in from outside of the greenhouse. The exhaust pipe is run to the outside of the structure.

- Sealed. This kind is a lot similar to the separated combustion type. The burner is completely sealed inside and there is no access to air inside the building. Sealed combustion heaters use direct vent both for exhaust and intake.

Heater Vents - Unvented. Being unvented heaters, combustion-produced gases are directly released to the heated area. Unvented heaters are only for temporary use because of the sensitivity of some plants.

- Gravity. The exhausted air from this type of heater should rise through the pipe and released outside, thus, the vents should be vertical. The air expelled must be replaced by outside air.

- Power. These power vented heaters have a blower that pushes air through the pipe and outside the structure. The vents may be arranged vertically or horizontally, and the vent pipes are smaller making it more efficient.

- Direct. This kind of venting is special to sealed combustion types. It has only one vent pipe with both the inlet and exhaust; one pipe is inside the other. The amount of air that leaves the pipe is the same amount that it pulls as intake. There is no additional air outside needed to replace the expelled air.

Another thing to consider in a greenhouse heater is its output range or the measure of the heat output. You can ask your nearby greenhouse store to check out your needed output range based on the area of your greenhouse and other factors. There are also web sites that can do the computation for you.

There are definitely several kinds of greenhouse heaters to choose from. For you to decide on which one to purchase, it is best to first do an assessment of your current greenhouse structure and its needs. You can also ask advice from experts in building and maintaining greenhouses for better results.
