As you know, the climate in most of Russia is rather harsh and does not contribute to the development of crop production. So, the frost-free period in the middle lane is only about 120 days.
In such conditions, most gardeners are forced to use greenhouses or greenhouses, which allow you to grow thermophilic crops, despite the cold, precipitation and wind.
And of course, the simplest and cheapest design that allows you to keep warm is greenhousemade with your own hands.
DIY greenhouse from scrap materials: pros and cons
Greenhouses, unlike greenhouses, have extremely modest size (the height rarely exceeds one and a half meters, and often can be only 0.8-1 meters), which makes the structure lightweight and stable in strong winds. In turn, this saves materials and labor when building a greenhouse.
Modest size is associated with another advantage in front of the greenhouse: there are no stoves or other heating devices in the greenhouse, and temperature supported by solar energy or the energy of rotting manure or compost, which is specially laid in a greenhouse for this purpose (along the way, enriching the air inside with carbon dioxide, and the soil with fertilizers).
Greenhouse easy to assemble and disassemble. The latter is especially important in late spring, when the heat of the day begins.
IN greenhouse for these purposes, numerous windows and doors are arranged, and in greenhouse there is no need for this: the covering material is simply removed, and that's it.
And the last plus, regarding only homemade greenhouses from scrap materials:
Such a greenhouse can be located practically on any site (in contrast to factory greenhouses, the size and shape of which are set during manufacture).
There is a greenhouse and minuses... First of all, greenhouses are unsuitable for use in frosty winters at temperatures well below zero. Greenhouses can only be used in spring or autumn, when the air and earth are in the afternoon. warm up, and frosts are possible only at night.
The second disadvantage concerns height restrictions. Since the height of the greenhouse does not exceed 1.5 meters, which can be inconvenient when caring for plants, and also limits the size of the plants themselves.
What materials are suitable?
The best materials are thick steel wire and polyethylene film... These materials are affordable, reliable and easy to use. A wire frame greenhouse will look like a vault, where the covering material will be stretched over several wire arches.
For the manufacture of the frame, and wood... Do-it-yourself greenhouse structures made of boards or timber have the advantage that they can be of arbitrary shape: triangular, trapezoidal in cross-section, etc.
The film can be nailed on one side, which will ensure greater reliability (if the film is dug in or crushed by stones, it can easily be blown off by the wind). Old window frames will do as well.

Preparing for construction depends on the materials of the frame. Wire arcs do not require any preparation at all - they can be immediately stuck into the ground. If you want to make a greenhouse out of old window frames, then it is advisable to treat them with an antiseptic and / or paint them so as not to rot.
Film you need to mark and cut the desired piece with scissors or a knife. If you need to glue two pieces of film together, you can use a hot iron. Pieces of film are placed on rubber or ebonite, covered with tracing paper or glassine on top so that the hot iron does not touch the film directly. After being carried out with an iron, orderly and strong seam.
To prepare the site on which it will be located greenhouse, it should be cleared of debris, stones, etc., outline the future boundaries of the greenhouse and measure them (in order to know how much film or window frames will be needed).
You can also do it yourself greenhouse from a profile pipe, from plastic bottles, from plastic pipes, from PVC and polypropylene pipes
How to think over the design and prepare the drawing?
In preparation greenhouse drawing the following points should be taken into account:
- it is desirable that the greenhouse is oriented south to north;
- if the greenhouse is made of window frames or knocked down boards, you need to provide ventilation;
- there must be access inside the greenhouse so that it is possible to care for plants, destroy weeds, etc.

Stationary or mobile?
For most crops, from radishes to strawberries, it is suitable stationary greenhouse... It is easy to build and requires minimal maintenance (close / open the plants depending on the temperature, water and thin / weed).
For seedlings of cucumbers, peppers and tomatoes, as well as for exotic southern plants that can die already with + 5-10, fit mobile greenhouse, which can be brought into the house at night. Such a greenhouse is made from a simple wooden box, to which wheels or carrying handles are attached. The box is closed from above glass or film, and instead of the usual, solid bottom, a bottom is made of boards through which excess water will flow (an alternative is to drill drainage holes in the bottom).
Types and cultures
Mobile greenhouses are mainly used for seedlings of all types, and stationary - most often for adult plants. Low greenhouses heated only by sunlight - for cold-tolerant crops: cabbage, radish, carrot, sorrel, dill, etc.
Biofuel greenhouses - for more thermophilic plants such as peppers, tomatoes, eggplants, etc.
Reference: Tall structures are needed for cucumbers, tall varieties of tomatoes, etc., it makes no sense to build them for the sake of undersized plants.
We build step by step
Consider the construction of a greenhouse using the example of the simplest design - stationary greenhouse made of wire arcs:
- You need to start with site preparation... Select a lit area of rectangular shape, elongated from north to south, clear it, dig up and level the soil with a rake.
- Prepare materials - a piece of film of the appropriate size (taking into account the height of the future structure and some margin, since the film will need to be dug in), and wire arcs with a height 0.6-0.7 m.
- If you decide to use biofuel, make two grooves along the long sides of your future greenhouse and lay straw, and on top - horse or cow dung.
- Stick in the wire arcs at a distance of about 20 cm.
- Cover the frame filmby digging it in at least on one side and crushing it with stones from the rest.
- When the soil warms up plant plants.
Thus, greenhouse differs from greenhouses simple design and the fact that it uses the cheapest heat sources: sun and decay. The weak points of such structures are their fragility and the inability to use in winter. But in the spring greenhouse will be a great solution that will help you get a harvest 4-6 weeks earlierthan outdoors without much effort.
