continues to talk about different types of greenhouses and hotbeds, this time the focus will be on the original pyramid greenhouse, in which, as they say, vegetables ripen faster, and at the same time they are large and highly useful.
Many useful properties are attributed to the pyramidal shape, due to the formation of a special geomagnetic field in it, which seems to have a beneficial effect. Many owners of pyramid greenhouses assure that they feel a surge of strength and no longer feel tired when working in the greenhouse.
Greenhouse Pyramid: Overview of Benefits
The pyramidal greenhouse also has an impressive number of completely objective, indisputable advantages.
Due to the decent height of the greenhouse, the superheated air inside it has the ability to rise up and not accumulate around the plants, thereby creating a microclimate, especially suitable for planting.
The frame of the pyramid greenhouse is smaller and lighter, which means that materials, including films, require a smaller amount, which reduces the cost.
The shape of the pyramid allows you to arrange plants in several tiers, plants with a high stem are planted at the bottom, and low-growing crops may be placed on racks.
The surfaces of the greenhouse in the form of a pyramid have a significant angle of inclination, which also gives an advantage in terms of illumination. In the morning and evening, the rays of the sun fall inside the greenhouse, and unlike arched greenhouses, it is almost not reflected. At noon, the rays from the sun at its zenith fall at an angle, are reflected, which allows to slightly reduce the midday heat.
Ventilating the pyramid in the greenhouse is extremely easy to organize, you just need to make a hole at the top and hot air will come out, as if through a pipe. Another plus of the pyramidal shape is a small shadow from it, which allows plants growing near the greenhouse not to lack a lack of light.
In the pyramid greenhouse, it’s quite simple to obtain and maintain the necessary level of humidity, for which it is easy to put a bucket of water inside, which is enough for a small internal volume of the pyramid.
The pyramid greenhouse has good transportability, its transfer to a new place is usually not associated with difficulties.
Finally, the pyramid looks original on the site - a kind of mysterious artifact, as if preserved from the time of Ancient Egypt.
A simple version of the pyramid greenhouse
A simple version of the pyramid greenhouse can be successfully used for growing seedlings. The construction of such a structure is cheap and does not require special skills. You will need four slats 150 cm long and a sufficient amount of film.
The upper ends of the strips must be connected, and the lower ones stuck into the ground 1 meter from each other so that they become the vertices of the square. The film coating for the faces is cut out in the shape of a triangle, it is desirable to use a two-layer film with a thickness of 150 microns and a width of 1 m.Then the pieces of film are fastened with a stapler or by compression with plates, you can also sew or weld pieces to each other.
So that the air does not stagnate in the greenhouse, the upper part of the hood remains open, but in bad weather this place can be covered. The film coating is put on top of the frame, the lower edge is pressed to the ground, for which purpose a margin in length is made. It is advisable to use a black film for one of the faces and place it on the north side. In the ground under the greenhouse, we recommend a shallow burial of hay, which, when decomposed, will generate heat and become a bio-furnace, warming the greenhouse from the inside.

DIY pyramid greenhouses: a canonical version
As a rule, the pyramid’s greenhouse has four faces, at the base there is a square with a side of 142 cm, the height of the wall-faces is 320 cm with a diagonal of 200 cm, the ratio of the diagonal to the height is 0.62. Such parameters correspond to the canon of the golden section, which was used by the ancient Egyptian builders. For the greenhouse, you need to choose an open place, you can not be particularly afraid of winds, the pyramid has good stability.
In the center of the plot intended for installation of the greenhouse. we dig a perforated pipe to a depth of 40 cm (a pole or bar with a cross section of 50 * 50 will also work). The pipe, firstly, will give structural strength, and secondly, will contribute to better circulation of air masses.
The greatest energy effect, according to experts who are versed in this, is possessed by pyramids, the diagonal of the base of which lies in the north-south direction. Now, along the perimeter of the future pyramid, it is necessary to drive in bars of 50-centimeter height, to which to nail boards for the base. Remember to leave room for the door on the south side.
To the base it is necessary to fasten 4 scaffolds making up the pyramid frame with screws, bring them together at the top point and fasten together.
At a level of 2 meters, we nail the transverse slats to which the film and shelves for seedlings will be attached. In a pre-allocated location, we will make a door frame.
It remains to cover the greenhouse with a pyramid of film material, having previously cut the pieces in shape and size of faces. It will take about 25 m of film or two sheets of polycarbonate. Most likely there will be quite a lot of scraps, so it’s worthwhile to figure out where they can be used rationally.
Covering the greenhouse structure with a film, do not close the top of the pyramid tightly, the top 15 cm of the dome, it is better to leave it uncovered or make a separate removable cap.
Along the sides of the base we make beds. For this we use boards or slate buried in the ground. We make the width of the beds larger so that in the center of the pyramid there is very little space left. Sometimes the beds are not very wide and then an extra bed can be made in the center.
To prevent the space in the upper part of the pyramid wasting in vain, we attach shelves to the transverse slats - a kind of “second floor”, on which boxes with seedlings of annuals, cabbage and other vegetables and greens can be conveniently placed.
The garden in the pyramid
What crops to grow in a pyramid greenhouse
To begin with, let's say that tall plants will be located correctly closer to the center of the greenhouse, and undersized at the edges. In general, all heat-loving crops grow well in the pyramid, for example, peppers and tomatoes ripen a couple of weeks earlier and are larger in size. It is convenient to grow eggplants in a small pyramid. When they require a “short day” mode, it is easy to cover the greenhouse with dark non-woven material, and remove it in the morning. The owners of the greenhouse of the pyramid note that the plants in it are not susceptible to late blight.
Each summer resident, with a little effort, can acquire a greenhouse pyramid. Even not particularly believing in the miraculous geomagnetic fields and pyramidal magic, such a greenhouse, as we have seen, is convenient in operation and can bring many benefits. And if you have an opinion or practical advice on the topic of pyramidal greenhouses, we will be happy to know about it.
