If you decide to build a greenhouse, we recommend that you familiarize yourself with instructions given in our article.

We select a place to place

The choice of place should be carried out taking into account that it will grow and ripen cultivated plants. So better stay on a flat plot of land, sheltered from the wind and with enough sunlight.

Mounting the structure on the soil with a slope will provoke it destruction.

The fact is that in winter the snow load is distributed unevenly, and for mid-latitudes it is often significant. For a shady place, for example, near trees, buildings or fence.

For a better arrangement of the greenhouse, spend water in it and electricity. To save on this process, have the greenhouse is not very far from energy sources. To grow plants in winter, you need to build a heated construction. In this case, you will have to make sure that on the coating the snow did not stagnate, because otherwise it would not penetrate into it sunlight.

Determine the shape and size of the greenhouse

Greenhouses vary in size, shape and materials used. However, the main difference is the temperature level, which is supported in them. In general, such designs can divided into 2 types:

  1. Unheated greenhouse – there is no heating in it, due to which the soil freezes in the winter. In the spring, the soil warms up for due to sunlight, and the greenhouse helps keep it warm. This prolongs the seasonal period of growth of cultivated plants. Such constructs commonly used to grow early vegetable crops and flower seedlings.
  2. The heated greenhouse is designed for heat-loving plants. IN they can maintain a certain temperature, which is most favorable for the growth of thermophilic cultivated plants.

Choose the shape of the greenhouse:

  • Gable roof structures are an ordinary type greenhouses having vertical walls.
  • A structure with a gable roof attached to the wall of the building – provides a great opportunity for light and air exchange.
  • The shed roof greenhouse is an extension to the wall of the house. For better solar heating it should install from the west or south side of the building. House wall in In this case, it plays the role of a power element of the frame; reliable protection against northerly winds is provided.
  • Trapezoidal, with a gable roof, has a high sustainability. It is warm and bright, unlike its counterpart with vertical walls.
  • Polygon provides uneven heating of the sides facilities. In order to avoid problems with overheating, it is very important to supply its windows or windows. This is necessary for timely airing.
  • The dome is adapted for gusty winds, but is not intended for growing high crops.
  • The tunnel is designed to grow vegetables that grow on earth, not high. It is most accessible for self production.
  • By type of arch allows you to grow low plants.
  • Mini greenhouse suitable for growing small quantities plants, and also convenient when there is a small space under landing.

Materials for the construction of the frame and coating

Square profileSquare profile

Now on the market there are an abundance of variations of materials for mounting the frame. For example, a steel frame is coated with powder paint. This is a fairly strong material, however, it is exposed corrosion, due to which it is short-lived. It is characterized by high thermal conductivity, but in exceptional cases this effect is not welcome.

The galvanized profile has a low strength, but not rusts. For its manufacture, a thin, easy deforming steel.

It is very durable and not subject to corrosion, of course, due to galvanizing. In addition, the frame can be made from processed antiseptic bars.

If we talk about coating, then every material that designed for this, it has both pros and cons. For instance, the greenhouse film is easy to replace. It’s also inexpensive undemanding to the conditions of use. Its shape may be arched with straight walls or traditional, in the form of an arch. Film can leave the winter in the greenhouse, so it will serve you no more than 4 years.

The greenhouse film has low thermal insulation and is unstable to mechanical damage.

PolycarbonatePolycarbonate

Recently, the greenhouse from polycarbonate. Polycarbonate has excellent thermal conductivity and light transmittance, durability. His main advantage ease, and also a possibility of operation about ten years.

If you prefer glass or glass to cover then the greenhouse should be strengthened by farms, and also by internal racks. Glass has the best light transmission, durability operation and ability to retain heat. However significant The disadvantage of this coating is its weightiness and fragility.

Making the foundation

FoundationFoundation

The foundation should promote uniform distribution loads of the whole structure. The base of the structure should be built exactly horizontally, with the possibility of outflow of rainwater. For protection against corrosion and decay, install between the frame and foundation additional sealing layer. It is important that the base of the greenhouse was very strong, because otherwise the walls can undergo deformation, and the foundation itself will collapse.

Before laying the foundation, it is necessary to calculate the depth freezing soil. Dig a special trench under the foundation, which should then be filled with sand and tamped. Height this filling should not exceed 20 cm below the surface soil. Around the trench it is necessary to make the formwork, towering approximately 20 cm above the ground. Along the perimeter put metal reinforcement into the formwork, and then fill it with concrete. Such simple manipulations will help make durable concrete reinforced belt under the greenhouse.

Build the frame and cover it

Greenhouse frameGreenhouse frame

Robust frame construction protects your crop from wind and rainy days. The standard type of greenhouse usually has a size of 6 × 3 m. After arranging and solidifying the base, you can begin to assemble wooden frame. Fix the supporting walls to the foundation. Then fix the horizontal beams on the top of each support. With side of the north, install a doorway measuring 2 × 0.7 m

If you chose a film as a coating, then after completion Mounting the frame, pull it. Use whole pieces of film coating. Fix the film with wooden slats, which are attached to the supports.

If you selected a profile, then usually you just need to twist it by predefined scheme in the instructions. On the other hand, you can use a profile to implement your own design frame.

We organize airing

Airing systemVentilation system

The method of vortex ventilation is a series of window leaves, which are located on the roof along the entire greenhouse. This way most efficiently ventilates the greenhouse without damaging thermophilic plants.

With a draft ventilation method, air enters through doors that are located at the end of the structure, but it can harm delicate plants that are sensitive to drafts.

If the structure is designed to protect the soil, then exposure to sunlight produces a greenhouse effect. because of a quick rise, the air in the greenhouse will stagnate, which will provoke the multiplication of pests and diseases. However microclimate can be adjusted using a ventilation system, providing fresh air.

The functioning of the ventilation system must be combined with the work heating and shading devices. By airing the greenhouse, you contribute to the hardening of both vegetable and fruit crops. Such events have a beneficial effect on seedlings grown for planting in open ground. 2 weeks before planting seedlings the greenhouse should be ventilated almost around the clock.

For the preservation of heat, penetration into it must not be allowed gusty winds and drafts. If your facility has small size, it’s enough to build only 1 window with each side of the roof. In general, for every 2 m of length there should not be less than 2 windows. It is important to speed up air exchange and cooling. install side vents in the frame, located slightly above the surface of the soil. They can be equipped as blinds or do the usual way. But this type of air exchange is inappropriate, if it is planned to grow plants brought from tropics. Due to the strong air currents that occur in windy days, tropical flowers may suffer.

So, you have already acquired some knowledge, only apply them in life! Of course, everything comes down to financial position, namely the choice of materials for the frame, foundation and coverings. However, the more reliable your building will be, the more years she will serve you!

Greenhouse heating

Greenhouse heatingGreenhouse heating

If you have built a decent structure with a foundation and covered its double-glazed window, glass or polycarbonate, organized high-quality ventilation, you can take care of heating the greenhouse. This will allow you to grow vegetables cultures loved by family members, even in the winter season. So how can you arrange heating? Today we look at 3 method, namely gas, wood and electric heating.

If you want to heat the building with gas, then you can do steam heating, but the easiest way is to use gas convector. However, you should first take care of the presence of gas in building. These units are equipped with special thermostats that eliminates the need for burner regulation. Burning particles will be removed from the greenhouse to the street using core coaxial pipe.

If the dimensions of the greenhouse are large, then it is more appropriate to use gas boiler air heating. Here the heat exchanger is blown special fan, and warm air is circulated around the perimeter aluminum sleeves. Small build air boiler heating can warm up and without wiring air. Just keep in mind that the coaxial pipes of the boiler with a closed burner and convector must pass through a wall made of non-combustible materials.

The most affordable source of heat energy is still firewood. The simplest solution is a potbelly stove, however, it is not economical. A more reasonable solution is Buleryan, which is a gas furnace. Around the firebox there are pipes that provide mixing of air flows in the room. She differs in high profitability and more rare bookmark of firewood. Even in severe frosts, it is enough to bookmark firewood only 2 times a day. Only the design of this furnace allows mix air efficiently.

Electric heatingElectric heating

Low-electric heating costs allows you to create a warm climate with little frost. For example, you can use an inverter household air conditioner. Currently produced models pump five kilowatts of heat from the street to the greenhouse for every kilowatt of electricity spent. However, the lower the temperature, the less efficient the operation. unit.

If you live in a climate zone where in the winter the temperature drops below -25˚С, it is better to heat the greenhouse with another way. In this case, more universal are infrared panels for heating air, because they are more economical, than fan heaters and heat guns. The fact is that infrared panels imitate natural heating of the sun. They don’t warm the air and they transfer heat to plants and soil. As a result, air at roof level Remains colder than soil and temperature below.
