The Pyramid greenhouse differs from other varieties of greenhouses in a non-standard form. The design has a number of advantages and advantages, as well as some features that should be considered when erecting a building with your own hands. When planning to install this type of greenhouse on your site, it is worth considering all these nuances. About the characteristics of the greenhouse design and the rules for its installation, read further in the article.

Design features of the Pyramid greenhouse

Greenhouse "Pyramid" is a structure of regular geometric shape, designed for growing vegetable crops. Usually a greenhouse of this type is built in the form of a regular tetrahedral pyramid, at the base of which is a square.

Did you know? In Russia, the first greenhouses for the industrial cultivation of vegetables were ordered to use Peter I.

Benefits

• The design has many advantages, such as:
• plants absorb a maximum of sunlight per day;
• The architectural solution of the greenhouse allows to provide the optimal microclimate to plants;
• in winter, snow falls from the roof and leaves the polycarbonate whole;
• it is convenient to ventilate the greenhouse;
• fruit ripening time is reduced;
• late blight affects less planted crops, compared with other types of greenhouses;
• saving on the amount of building materials during the construction of the greenhouse.

Disadvantages

The only drawback of the pyramid greenhouse is its small area. Tall and roomy pyramidal greenhouses are found in greenhouse variants. For personal purposes, it is difficult to build a building with a dome of sufficient height and long walls.

Selection of drawings and optimal greenhouse sizes

Before construction, the farmer should determine the size of the greenhouse structure. To draw a drawing, you need to know three parameters: height, rib length, and length of the base side.

Important! To calculate the parameters of a greenhouse, it is enough to draw a pyramid on a sheet and perform calculations according to the Pythagorean theorem, known to everyone since school times.

The optimal dimensions of a regular pyramid with a square base and 4 faces:

• height - 3 m;
• rib length - 3.6 m;
• base side length - 3 m.

Based on the above parameters, a spacious and roomy greenhouse is obtained.

How to make a greenhouse "Pyramid" of polycarbonate with your own hands at home

For high-quality assembly of the Pyramid greenhouse, it is necessary to build a foundation, assemble the frame and fix the polycarbonate coating on the frame.

Foundation selection

The pyramid greenhouse can be installed without a foundation. The construction itself is sturdy. In addition, a greenhouse without a capital base can be moved around the site. However, the foundationless structure has two drawbacks: poor preservation of the temperature regime of the inner space and germination of weeds from the outside. The best way to make a greenhouse stronger and more durable is to install a strip foundation.

Make it as follows.

1. Along the perimeter of the future structure, trenches of 0.5 m deep and 0.3 m wide are excavated.
2. A layer of sand 5 cm thick is covered at the bottom.
3. A layer of gravel, also 5 cm thick, is placed on a sand cushion.
4. A waterproofing film coating is placed on top of the gravel.
5. Along the perimeter of the trench, formwork is placed so that it rises 0.2 m above the soil level.
6. In trenches with formwork, angular fastenings and fittings are installed.
7. A cement mortar is prepared and the substance is poured into the formwork.

After 2 weeks, when the cement hardens, you can proceed directly to the assembly of the structure.

End assembly

The correct pyramidal greenhouse, in fact, does not have end sides, since all faces converge at one point. However, the first thing to do is to collect the side in which the door and the opposite side with a window will be mounted. They will be end-face.

Important! The end sides are mounted so that the door and window openings open upwards.

Assemble the supporting structure from a metal profile according to the drawing and fasten to the base with the help of corners. In the upper part, the end faces are connected with fixing bolts.

Frame assembly

After assembling the end faces, the frame of the greenhouse is almost ready. It remains to fix the vertical and transverse crossbars from the metal profile to the sides so that it is more convenient to fasten the polycarbonate sheets. When designing a small greenhouse, you can leave a through opening and attach a solid polycarbonate sheet in the form of a triangle.1 - foundation; 2 - galvanized casting; 3 - a supporting board; 4 - rib; 5 - a lateral level of a window box; 6 - a lateral level of a door frame; 7 - the upper element of the central rib; 8 - upper connecting element; 9 - the lower element of the central rib; 10 - lower connecting element.

Frame cladding

It is customary to sheathe the Pyramid greenhouse with polycarbonate material. The sheets are pre-cut into pieces according to the drawing. For fastening, it is best to use self-tapping screws. To save financial resources, the greenhouse can be sheathed with a film coating. In this case, it is better to initially make a wooden, rather than a metal frame.

Tips for the maintenance and operation of the pyramid greenhouse

The pyramidal greenhouse is convenient in that it does not need to be dismantled for the winter. A structure without a roof does not bend under the weight of snow - due to this, its integrity is guaranteed. Gardeners advise using the parameters of the pyramidal design to adjust daylight hours.

For this, a small structure (up to 2 m high) is covered with black material. Thus, it is possible to reduce the duration of daylight, which is required by some varieties of cucumbers, tomatoes and other plant crops.

Important! Be sure to sanitize the greenhouse parts with a 1% potassium permanganate solution before each planting season. Thus, the spread of infectious pathogens that have survived from the previous season can be avoided.

According to reviews of vegetable growers, the pyramid greenhouse is fully justified due to many advantages. This is ideal for growing small volumes of plantings of thermophilic crops. For best results, use the advice of experienced agronomists in the operation - recommendations will help to get a high-quality crop annually.
