A familiar picture in August: in the apartment, in dark and not very places, heaps of tomatoes lie on the newspapers. Taken from a bush at the stage of technical maturity. For ripening.

This is especially true in the northern regions. And what is this ripe tomato if you eat it straight from the bush?

Alas, in conditions of too short a summer, it is not always possible to try. In such regions, only greenhouse method of growing tomatoes.


Tomatoes are thermophilic plants that do not always grow and bear fruit well outdoors. And although today many hybrids have been bred that are resistant to adverse weather conditions, they still mature better in a greenhouse.

  • tomato grow at optimal temperature and humidity;
  • yield increases at least 2 times;
  • ripening occurs 2-3 weeks earlier than in the open field;
  • the risk of disease is reduced.

All conditions are satisfied when compliance with agricultural technology for growing tomatoes in protected ground, which has some differences from caring for plants on the street.

The size

Most often grown in greenhouses tomatoes of indeterminate species... These are plants with a stem up to 2.5-3 m high. It needs support and a garter.

Therefore, the structure must be high. Its area is calculated depending on the needs.

Most often bushes planted according to the scheme 50 x 50 cm... Thus, it is not difficult to calculate the size.

When building a greenhouse, it should be borne in mind that other vegetables can also be planted on this heated area, which also love warmth and are well adjacent to tomatoes. Therefore, the area can be calculated with a margin. Standard the greenhouse provides for three beds.

A small indent is made from the wall to the garden bed, 15 cm on each side. The width of the garden bed should be at least 60 cm, and the aisles 70 cm. In total, we get 3.5 m. Here is an illustrative example of the calculation: the height of the greenhouse should be at least 2.5-3 m so that the bushes fit in height. Everyone chooses its length according to his own needs.

Preparation for construction

As with any construction, the construction of a greenhouse on a personal plot requires thoughtful approach and preparation.

A place

The first thing to do is to determine where it will stand. If the relief of the site is difficult, it is better to choose place on a hill... Swampy places will not work, as the plants will die from excess moisture. The place must be level so that the greenhouse is stable and does not collapse from the wind. There should be no trees or buildings nearby that give shade, otherwise its inhabitants will lack light.

If you plan to build a heated greenhouse for year-round use, it is better to build it. near the house, so as not to carry out communications - water and electricity - to the other end of the site.

A type

Before making drawings, decide what you will grow in the greenhouse. Its size depends on this. In addition, it is important whether she will capital or collapsible. A foundation is needed under the capital, a collapsible polycarbonate is mounted directly above the beds.


The foundation under the capital greenhouse performs several functions:

  • gives stability to the structure;
  • separates walls from the outer layer of the earth for greater thermal insulation;
  • blocks the path of garden rodents.

Foundations are different, depending on the type of greenhouse:

  • block foundation for a greenhouse made of polycarbonate. It protects against excessive moisture in the soil, therefore it is well suited for areas located in low-lying places;
  • concrete-brick the foundation is good for greenhouses that will be used in the spring and summer, because it does not protect the beds very well when the soil freezes;
  • strip foundation from a bar it is laid for temporary greenhouses for 2-3 years due to the fact that the tree begins to rot and collapse;
  • concrete foundation-monolith poured under capital greenhouses for winter growing vegetables. Such a foundation perfectly protects against cold weather, pests and excessive moisture. But it is expensive and recommended for areas with moving soil.

Materials (edit)

Having made a drawing and having decided on the dimensions, you can proceed to the selection of materials.


For polycarbonate greenhouse frame a metal profile is used... Its advantages are its low price and lightness, its disadvantage is that thin metal is not resistant to deformation.

If wooden posts are used, include in the list of materials impregnation-antiseptics and paint for them. The advantages of the tree are environmental friendliness, the disadvantage is susceptibility to decay.

Galvanized steel profile - the most suitable material. It does not deform, it is easy to install, zinc plating protects against corrosion.


The cover is selected in accordance with the operating mode of the greenhouse. Suitable for summer film, especially since manufacturers offer a wide selection of reinforced, reinforced and other films.

Glass cover installed on permanent greenhouses, built on level ground with a good foundation.

If the soil under it "plays", the glass may crack. This can be attributed to the disadvantages of the glass coating. The advantages are excellent light transmittance - up to 92%.

The most common and convenient material is polycarbonate. You can build a greenhouse of any shape from it - it is flexible and durable. Polycarbonate provides good thermal insulation, UV protection and 86% light transmission

Before starting construction, it is necessary to prepare the site.

  • pegs are driven in on the leveled surface of the earth in accordance with the dimensions of the future greenhouse;
  • dug out foundation trenches a depth of at least 40 cm (along the perimeter or tape under the entire greenhouse);
  • trenches covered with sand by 20 cm and are carefully tamped;
  • a formwork is being built (its edge should be 20 cm above the ground) and a mixture of cement with sand and crushed stone is poured;
  • after the mixture has completely solidified, brickwork is made on it in 1-2 rows and waterproofing is laid. It is attached to the masonry with anchor bolts;
  • frame slats treated with an antiseptic and sawn in accordance with the drawing;
  • vertical posts are fixed to the foundation. The distance between the support posts must correspond to the width of the polycarbonate sheets;
  • on top of the racks, bars are attached along the perimeter - this is a strapping that gives rigidity to the structure;
  • the structure is reinforced in the lower and upper corners sawn-off bars at an angle of 45 ° to the main posts and harness;
  • rafters are installed and a ridge beam is attached;

  • the cover is attached to the frame.

The coating must be airtight, therefore, the joints can be additionally filled with sealant. It is convenient to attach polycarbonate to the frame with thermal washers and self-tapping screws.

Such a greenhouse will last a long time if the wooden parts are impregnated with protective mixtures and painted several times a year.

Having spent moderate money and silent labor on the construction of a capital greenhouse, you can get good harvests from it for many years.
