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.

Here are some of the available greenhouse kits that are out in the market:

Sunshine

These are greenhouse kits which are framed by fantastic redwood. They have polycarbonate insulations for covering the plants. Another good thing about the sunshine greenhouse kits is that they provide a lot of space because they have very tall frames (usually 10 feet tall). They are also very easy to install because the insulated polycarbonate insulations are already built into the frame. Their prices rage from a thousand dollars to around four thousand.

Cross Country

These are high quality greenhouses which have several modified options which are available. They are framed with aluminum which provides sturdy support for the greenhouse. They also come with doors with screened windows and an automatic ventilation system. They are priced from $2,500 to $30,000 dollars. They can be quite expensive but the price speaks of their quality.

Little Greenhouse

These are greenhouses which provide economy for people who would want to engage in plant cultivation. These kits come with structures which are protected from ultra-violet rays. They also include bench setup and an exhaust fan. They come with a PCV frame, a four millimeter polyethylene covering made up of plastic. They provide optimum environments for plant cultivation. These are recommended for beginners.

Juliana

Juliana greenhouse kits are very popular for their rust-free frames which are made from aluminum and a poly-carbonate, twin-wall covering which provides cultivators with a long time of enjoyment at a very affordable price. There are many models under this kind of greenhouse kit. They come in very affordable prices- as low as 65 dollars.

Portable

These are very inexpensive greenhouse kits which are very easy to assemble and disassemble. They are recommended for seasonal gardening because one can easily put them up and store them away when they are no longer needed. They come with one of the most durable coverings which are made with plastic film. Their structures are made of steel. They also come in with a build-in door and a screened ventilation windows. They also have storage bags. They are available for the price of 300 dollars.

Hobby Gardener

These greenhouse kits are covered by original “snapglas” panels. These are panels which have the clarity that is offered by glass and the sturdiness and durability possessed by polycarbonate. They are also equipped with barn-like roof which provides more room for plants. They also include hinged-doors, hinged-roof and ventilated walls. They are priced at around a thousand to two thousand dollars.

There are many kinds of greenhouses for different kinds of enthusiasts out there. One must be keen in choosing the kit that suits his needs and preferences. Moreover, he must be able to know which greenhouse will provide the optimum environment for the growth of the plants which he will be cultivating.

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.

The Proper Way To Fertilize Greenhouse Plants

A plant newly potted will need some time so that it can grow new roots in order to absorb or take in the fertilizer that you will apply. There is a particular way that you should fertilize greenhouse plants.

How you fertilize and what type of fertilizer you use is dependent on what kinds of plants or crop you grow in your greenhouse, because every crop has a particular requirement with regards to nutrients, and this requirement should be met.

For house plants, it is usually much easier to fertilize a large group together. Generally, plants need to be fertilized every one or two months while there is rapid growth and all throughout the winter season, twice or once only.

Alternatively, you can apply the fertilizer more frequently when using a liquid fertilizer diluted in water; this familiarizes certain plants that otherwise be injured when you use a fertilizer of full. Generally half of the recommended strength or dosage means that you use only half fertilizer in every plant.

Annual plants can flourish very rapidly and will require fertilization every two weeks throughout their “short season”. A few flowering plants such as the Azalea must not be applied fertilizer while in their blooming or flowering stage.

Most fertilizers that are generally used have considerable amount of nitrogen (50 percent); they contain the preferred amount of nitrate f and are usually labeled and identified as “peat-lite”. This type is preferred and recommended for greenhouse hobby use. The N-P-K ratio can be verified by reading the label that is found at the fertilizer bag.

Fertilizers are usually applied at the amount or ratio of “200 ppm nitrogen” fertilizer like “21-5-20” or “20-10-20”. This is completed by continuous liquid application; this ratio is the basis for mostly all pot grown “greenhouse plants”. The rate may be adjusted downward or upward depending on the plant that is grown.

Any pre-mixed or ready mixture of fertilizer for the kind of plants that you grow is acceptable; for most flowering and foliar plants. An N-P-K ratio analysis that is similar to “1-2-1” will supply a balanced growth.

Soluble fertilizers can be conveniently applied and deliver faster results compared to solid fertilizers or “slow release” gravel-like fertilizers. Just apply the solution in a manner like you are watering your plants, however, instead of water, use the fertilizer solution, making certain that the plant soil is slightly moist before application. You should never apply fertilizer solution onto plants with dry soil the roots can be injured by the fertilizer chemicals; moist soil further dilutes the chemicals.

Apply fertilizers always following or much weaker dose than the suggested dilution strength, and not stronger, as seedlings, newly established cuttings, and developing plants will derive benefit from much weaker solutions; stronger solution will only injure young and soft roots.

There are many injections or siphon devices available in the market to make application of soluble fertilizers much easier; however, when you use them, be certain that you install “backflow preventers” in order to keep the nutrients or chemicals in the fertilizer solution from contaminating your water supply in the home. Likewise do not water your plants with a “water-softened” water due to its “high salt” content.

Choosing The Right Greenhouse Design

When you have a greenhouse, it means that you never have to quit gardening just because of weather conditions. You can keep on propagating cuttings and seeds and grow several plant varieties whatever the season.

When choosing a greenhouse, select a greenhouse style that matches the design of your home and the layout of your garden. Weather conditions should also be taken into account, as when your area experiences heavy snows during the winter, most likely you will not select a flat or straight roof design, rather a roof that will allow the snow to slide off easily.

The standard free-standing with curved or peaked roof greenhouse up to now is very popular that can be found in so many gardens. The rectangular or square shape permits for utmost growing space for plants, usually designed with benches on the sides and at the back.

Lean-to or home or wall attached greenhouses designs are manufactured and used when there is limited space at the backyard. These greenhouse designs are very accessible and convenient for connecting much needed water and power supply.

When choosing a certain design in the market, the “sky's the limit”. Small solariums of various designs are widely available, medium and large sized greenhouses and even prefabricated greenhouse kits for easy installation.

Here are some greenhouse designs:

1. Gable greenhouse. This design type usually is attached to a wall or garage or any structure utilizing only half the gable’s actual gable design. Generally, this type has flat roof panels but slightly sloping and vertical sidewalls. At times, the gable types of greenhouse are also attached to another greenhouse employing the use of the end wall rather than sidewall.

2. Barn style greenhouse. This design type is, as the name suggests shaped similar to a barn having wide roof and interior and with shorter walls. This design is usually incorporated in a garden of country setting or theme or a rustic garden appeal. This greenhouse design can be attached to another greenhouse or can be beautifully constructed in a garden freestanding.

3. Dome greenhouse. This design is identical to a dome, meaning it is half a ball and placed directly on land. This design can not be attached to a structure and only can be constructed as a freestanding type of greenhouse, as this design has no sidewalls. This type of greenhouse is a bit expensive to make due to the many pieces of different glazing that generally are needed to complete this design shape.

5. Gothic style greenhouse. This design type has a very historical gothic appearance. The walls and roof are formed in such a manner as to create a continuous form, allowing snow to fall down easily. This design type can be either attached or freestanding, however it is usually not recommended attached except when your home’s design is very much similar to a gothic design.

6. Hoop greenhouse. This type of design is constructed with a metal pipe or PVC to make the hoop’s shape then enclosed with plastic covering. This type of design is very cost effective on your initial purchase, but the maintenance of continuously replacing the cover (plastic) can really add up.

One will find that the majority of greenhouses are manufactured from aluminum material that is weatherproof and lightweight. Galvanized steel also is sturdy and lightweight. Wood can also be used, but one has to make sure to use a lumber that has been pressure treated such as redwood or cedar because these are weather resistant.

As to whatever greenhouse design should you decide on, be sure to look for a structure with the highest strength and stability and must have these features:

• Will be cable to endure extreme weather conditions, like very high winds and snowfall build up.

• Should have the necessary support for grow lights, sidewall shelving and hanging baskets.

• Should have an intricate detail of having hinged screened storm doors as well as large side or individual roof vents.

• A wide selection of styles and sizes offered. Keep in mind that costs can limit your greenhouse size, however extensions can later be added when needed and when you already have enough budget for it.

• The door may be easily adjusted to be dropped or lowered into the foundation’s opening so to get rid of an elevated step when you feel that it is needed.

Take note that often, most greenhouse owners complain of a limited space when they built their greenhouse on a budget. So whatever design you choose, just remember to get the largest that your money can buy.
