Cheap breeding conditions are especially important for the development of the plants. In domestic breeding, greenhouses are sometimes needed for some species and strains of plants. On Glasshouse is a room with its own microclimate, which is good for plant breeding. Greenhouses are needed to support both the initial development and the further development of the plants.
If you need a greenhouse and want to save some money, you could build it yourself. In today's article we give you the best tips for building a greenhouse. We tell you what you should consider and show you some pictures.
Part I: Choose the place
1. First you should find the right place for the greenhouse
The south or north side of a garden (depending on the location) are best suited for this. The most important requirement is continuous light. That means the house and all the buildings around must stay behind the greenhouse.
2. Give preference to the side where the sun shines in the morning instead of the side where it shines in the afternoon
Although the best option is that the plants in the greenhouse are exposed to the sun's rays all day, the plants grow faster under the morning rays. If there are trees or tall bushes near the greenhouse, be careful not to cast shadows on them until late in the afternoon.
3. Pay attention to the difference between summer and winter sun
If the area is open to the east, it will get sun between November and February. In winter the sun is lower and the trees, houses and other buildings are a problem. Choose no place if there are evergreen trees nearby. Deciduous trees have no leaves in winter and the sunlight is let through.
4. Choose a place where you have access to electricity
Most greenhouses need warmth and ventilation to keep the internal temperature optimal. It is better if your greenhouse is an extension of the house, so you use electricity from the house. The southern side of the house is better for an extension.
5. Select a dewatered area
Otherwise you will have to empty the rainwater yourself. If the surface is uneven, you should take care of the drainage. Maybe you should get yourself a rainwater cistern, where the rainwater from the gutter goes. Saving electricity and water will help you reduce costs.
II. Part: Choose the type of construction
1. Measure the area
The larger the greenhouse, the greater the cost of construction and heating. The standard size of a greenhouse is 2.4 by 1.8 meters.
2. Design the extension
You could use one of the house walls for it, by serving as a support wall. If your house has a brick wall, it is easier to maintain a balanced high temperature. The construction is very easy to build, even if you work alone. You can fix the structure with structural steel mat and wooden beams. Cheap offers for greenhouse accessories can be found on the website of OBI.

3. Build a corrugated iron hut
A corrugated ironwork is a vaulted ceiling that can be built with steel or PVC pipes. The arched shape leaves less space for storage than rectangular structures, but it is a cheaper option as the materials are cheaper.

4. You can also build a construction with a stiff frame
IIPart I: Materials for coverage
1. UV-stabilized polyethylene
The plastic cover should be replaced every few years with a new one. Occasionally, it should also be washed from time to time. The plastic cover is less heat resistant than the glass, but it is well suited for shelters and corrugated ironwork.
These building materials can be arched around the frame of the greenhouse. With this material you save up to 30 percent energy. Polycarbonate is 200 times stronger than glass, so there is no danger of it breaking. It is also UV stabilized and lets the sun's rays through.
If you want to build the greenhouse with a stiff frame, you save a lot of money if you buy fiberglass instead of glass. Be sure to buy clear fiberglass. It should be replaced every 10-15 years with a new one. Invest in higher quality fiberglass, as low-valent vapid rays let through.
4. If you want to choose glass
Note that glass breaks very easily and is more expensive to replace. You can build your greenhouse with glass only if the greenhouse has a foundation. For single greenhouses, the above variants are better. It is desirable to use toughened glass as it is stronger and more resistant.
Part IV: Part Construct the frame
1. Twine and plywood are good, to mark the size of the greenhouse on the ground.
2. Affirm with reinforcing bar
You can fix the frame construction every 1.2 meters with reinforcing bar or PVC. Once the reinforcement bars or PVC bars are erected, you can use PVC material to make a 6-meter-high loop to secure the frame. Attach the carriers to the floor and stretch the plastic around the structure.
3. Trowel, gravel or pebbles on the ground around the structure for extra drainage
You can either do the stones around the structure yourself or set someone to form a concrete foundation.
4. Treat the wood
It is possible that untreated wood will break up in 3 years. Use sheet metal for fixing the wooden boards.
5. Seal the cover as well as possible
The more expensive the cover, the harder it is to seal.
Part V. Check the temperature
1. Install fans on the sides of the greenhouse in diagonal lines
In winter, the fans should work almost all the time so that the whole greenhouse is heated. Also mount fans on the ceiling.
2. Ceiling outlets are also very important
They should be mounted with an adjustable mechanism so that they can be opened in summer.
3. Install electric heater
Solar heat is not enough, so an electric heater is necessary.
4. Mount the thermometer / thermostat
Mount the thermometers / thermostats at different heights to monitor the temperature throughout the greenhouse.
VI. Part: Additional planning
1. Learn about the conditions for plant growth
The more sensitive a species of plant, the less plants of other species you can breed in the same area. Well built is this greenhouse, where the plants do not freeze in winter. A warm house is a greenhouse with tropical temperature. You should choose the right temperature and make sure it stays constant.
2. Water supply
The greenhouse needs water supply. The best option is to supply water from cisterns or with a water hose.
