In a complex greenhouse, you can plant different crops in a specific order and position.
Knowing some of the rules regarding planting plants and building an integrated greenhouse will allow you to harvest a good and varied crop, not only in the summer but throughout the year – of course, if the greenhouse is equipped specifically for year-round operation.
At first, just like in the construction of other structures, a certain plot of land is selected for the greenhouse. Depending on the chosen place, its external dimensions and configuration are determined.
Then you need to draw a plan of all the ridges and paths that are supposed to be arranged inside the building. There are certain rules for their devices. Ridges should be 0.8-1 m wide, it is better to arrange them from north to south.
It is not recommended to place the beds on the sides of the greenhouse, near its walls. It is better to lay tracks with a width of at least 0.6-0.7 m so that it is convenient to move along the beds and perform various work. Between the beds also need a track with a width of 0.5-0.8 m (depending on the width of the greenhouse and the size of the beds).
If the tracks will not be concreted, they must be covered with a thick layer of dry sawdust or wood chips, since the soil in high humidity conditions will serve as a constant source of dampness and rot, causing the development of various diseases in plants.
The height of the greenhouse depends on the height of the ridges and plants, as well as on the width of the structure (standard height is 4 m, but with large width of the structure it should be minimal – 3.2 m). Earlier it was said that in a too high greenhouse, warm air will rise up, while the plants will remain in the cold zone.
The main door in the greenhouse must be mounted on the south side. In a large greenhouse for the convenience of care and watering plants, an additional entrance is required. It can also be equipped on the south side of the building in the form of an opening closed with a thick film. When any work will be carried out (watering, export and import of soil, etc.), this film can be bent, and after completion of the work, lower and firmly fix it on the frame.
Window leaves in the design of the greenhouse should also be provided at the planning stage. It is advisable to make two windows, every 1 m2, in the upper part of the greenhouse – one in the north end and the other in the south.
For additional ventilation along the entire length of the southern and northern ends, 30-40 cm wide openings are made, which are covered with a 50 cm wide film. Its upper part should be firmly nailed to the frame along the entire length, and the lower part should be fixed free, but so that at the right time it was possible to raise the film to ventilate the greenhouse.
If high beds are equipped in the greenhouse, in the warm season for two months you can leave large windows in the upper ends of the structure open.
Plants in the greenhouse will live by the principle of “the head is in the cold, and the legs are warm”, which is very useful for them. In addition, due to regular ventilation, the maximum amount of solar heat and light will enter the greenhouse, water will not settle on the film with condensate, the influx of fresh air will stimulate the movement of nutrients – all this together causes the plants to grow actively and increases their fruiting.
Roof fastening should not interfere with work in the greenhouse, as well as the location of the support posts should not interfere with the creation of mini-greenhouses above each garden bed. Mini-greenhouses are arranged for seedlings to protect it from spring frosts. They are made in the form of a simple triangular frame of thin metal rods, wooden battens or plastic planks, tightened with a film. These mini-greenhouses seedlings immediately after planting cover for the night.
How to Make an Insulated Greenhouse with Your Own Hands
Before the construction of the insulated greenhouse, it is necessary to prepare a site for it (the surface should be carefully leveled and marked), and then a trench should be dug. Then a pile base is arranged, retaining walls are attached, beds are formed and steps are made to enter the greenhouse. Construction technology will depend on the chosen form of the greenhouse and the material from which it will be made. A framework assembled in accordance with the description is installed on the prepared foundation, and then the film is stretched.
The complex greenhouse is quite wide, and to make it more convenient to cover it with film, you can build “scaffolds” – put barrels, and put wide boards with a thickness of 40-60 mm on them. The coating must be laid from the top edge at the same time both to the right and to the left since if you leave one end open, the canvas can be torn by a gust of wind. It is advisable that two people work on both sides of the greenhouse. If there is no assistant, first of all, you need to lower the film from the side where the wind blows.
Inside, around the entire perimeter of the greenhouse, to a height of 40-50 cm, you need to firmly attach the black double film, which will act as a battery. Outside it should be covered with a simple film to retain heat inside the greenhouse.
For the top of the greenhouse, it is better to use a film with a thickness of 150 microns, and for the sidewalls and ends – 120 microns.
