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.
Many people are growing more and more enthusiastic about getting themselves a greenhouse. Greenhouses are very practical to have nowadays especially when the prices of crops in the market are becoming more and more expensive.
In building greenhouses, one has several options to choose from. One can actually hire a professional greenhouse expert to guide him throughout the whole process of building his greenhouse. From the creation of plans to the actual creation of the greenhouse, one can use the services of a professional. However, this approach will entail a lot of costs. The professional fees will definitely take its toll in the pockets of the greenhouse enthusiast. Another way to do it is to buy resources about building greenhouses. There are many resources out there that contain greenhouse plans and other tips which can be used in building a greenhouse. However, there are sources which give free plans and tips which can be very useful, especially for greenhouse enthusiasts who are just beginning.
There are several parts of a greenhouse which need careful consideration and planning. These are:
1) Base
The base is made from sawn timber. This kind of timber can easily be availed from local timber merchants. This timber is more commonly found in fences. The base for our plan is measured at 2400 mm by 3000 mm.
2) Side walls
The side walls should be built from 75 by 50 tanalised sawn timber. They usually come in 4800 mm.
When the base is established on a flat ground, the two side walls should be built. The two side walls should be put upright and temporarily in place on top of the base. They are to be attached to the base using galvanized nails.
3) Roof frame
The roof frame should also be built using the 75 by 50 tanalised sawn timber. The roof frames should be placed above the side walls. A roof frame should be placed at each end of the side walls. They are also to be attached using galvanized nails.
4) Windows
The windows should be made of 50 by 50 sawn tanalised timber. Some people would want a couple of windows for their greenhouses. The windows should be hinged so as to allow regulation of temperature.
5) Covering
The greenhouse covering should be made up of polythene which is resistant to ultra-violet rays. The covering is to be placed using thin battens which will hold the polythene to the greenhouse. The battens are to be nailed to the greenhouse studs and roof rafters. One must be cautious about the kind of polythene which he will avail from the hardware store since most of the suppliers only have polythene which is not ultra-violet-resistant.
There are other things to consider when building greenhouses. Here are some of them:
- One should check the local building regulations before engaging into greenhouse construction. If in any case that there are restrictions regarding deeds, one should look at the requirements regarding set backs and regulations about easement. Hoop houses are greenhouses which are made from frames which can be easily disassembled. These kinds of greenhouses are not considered as permanent structures and therefore exempt from the regulations concerning such structures.
-One should make a layout of the whole yard and the house before he constructs a greenhouse. A greenhouse would often times become the centerpiece of a garden or a yard and it is much recommended that people plan before putting a single nail into it.
-Time management and budgeting are two important things to constantly consider in building a greenhouse. One should allot around eight to twenty thousand US dollars if he is serious about constructing a quality greenhouse. However, there are greenhouse kits that are available out there that are not as expensive. One should know what to spend and how to spend it. The time table in constructing a greenhouse should be set according to the plans of the owner. Greenhouses can be built in a couple of days to a couple of years. It all depends on the owner.
One may find many free greenhouse construction plans in the Internet. All one needs to know is the know-how’s of search engines. These free plans come with good tips and wonderful illustrations to guide one in constructing a greenhouse for his plants.
