Such greenhouses can be built on a wooden or metal frame and covered with foil. The greenhouse requires annual renovation, but it is quite cheap. Suitable only for seasonal cultivation in soil.
For year-round cultivation of tomatoes capital buildings are neededequipped with a heating system. Such greenhouses are erected on a solid metal frame with an anti-corrosion coating. Glass or polycarbonate is used as a coating.
The latter is suitable for arched greenhouses, sheets can be bent and cut without fear of damage. In regions with cold climates double glazing recommended... The air between the layers of glass or polycarbonate creates a thermos effect, which helps to reduce heating costs.
For year-round cultivation, a greenhouse with a pitched roof is more convenient. Sizes vary from 100 to 500 sq. m... Industrial greenhouses are even larger, with an average size of about 1000 sq. m.
Such structures imply overhead cultivation, hydroponically or aeroponically... A significant drawback of tomatoes grown in a nutrient solution is the recognizable watery taste and the absence of a characteristic aroma.
An ideal tomato greenhouse should be tall enough. The north wall can be laid out with cinder blocks or timber. A blank wall will protect the landings from the wind and will help keep warm. The preferred design is with a pitched roof, on which snow does not linger.

Choosing a variety for closed ground
In the greenhouse, it is preferable to grow hybrids specially designed for indoor use. It is better to choose tall, branched varieties. On such a bush many fruits ripen at the same time, which increases the productivity of greenhouses. Tall bushes can be combined with smaller ones planted around the perimeter. This arrangement will allow optimal use of the scarce space.
For indoor use, both early and late varieties are suitable. In the middle lane, it is not recommended to plant especially sweet hybrids of southern selection, they are very sensitive to temperature fluctuations and can be affected by pests.
Specialists recommend choosing hybrids, zoned for a specific region. The varieties of Russian selection, as well as American, Dutch and Polish tomatoes, have proven themselves very well.
When choosing the right variety, it is worth considering:

In small farm greenhouses, it is better to grow tomatoes in soil. Their taste is much higher, which makes it possible to sell products at a good mark-up.
Greenhouse must be equipped with a ventilation system and automatic drip irrigation. Tomatoes are sensitive to moisture levels, but they do not like stagnant water in the soil. On hot days, shading is required using special curtains that cover the south side of the greenhouse.
The heating system can be different. Industrial greenhouses heated with built-in boilers and pipes laid underground. Farm structures can be heated with air heaters, stove stoves and even bonfires. The use of biofuels from a mixture of rotted manure and straw will also help.
To maintain the desired microclimate in winter, open tanks with diluted mullein are installed in the greenhouse. Vapors activate the process of photosynthesis necessary for good fruiting.
Tomatoes in a greenhouse need light, nutritious soil, in which complex mineral fertilizers are regularly applied. Top dressing from a mixture of superphosphate, potassium salt and ammonium nitrate paid every two weeks... Lack of nutrients slows down the formation of ovaries and fruit ripening.
