With the onset of the planting season every gardener strives as best you can prepare to the beginning of planting vegetable crops.
At the same time, sincere adherents of dacha farming try to grow seedlings on their own site with their own hands. For this absolutely it is not necessary to build greenhouse large sizes, but it is quite possible to get by with the construction of a mini-greenhouse made of polycarbonate.
Polycarbonate mini greenhouses - compact and lightweight structures, in which you can grow various types of vegetable crops. Cellular polycarbonate is an excellent option for covering greenhouses.
He is a two-layer material with rows of cells located inside. Polycarbonate is much stronger than film, much lighter than glass and bends well, which allows it to be shaped like an arch.
Mini greenhouse equipped with this material, has the same degree of thermal insulationas is the double-glazed frame construction.
Such a structure can be successfully used on the personal plots of private houses, it is also an indispensable option for gardeners.
Advantages and disadvantages
Like any construction, a mini greenhouse made of polycarbonate has positive and negative sides... The advantages include the following indicators:
- easy and simple installation of the structure;
- high degree of thermal insulation;
- excellent level of light transparency (not less than 92%);
- protection of plants from ultraviolet rays, due to the presence of a special coating;
- the strength of the material (200 times more than that of glass) and the ability to withstand shock loads;
- polycarbonate resistant to aggressive environments and provides plants with good protection from acid precipitation;
- Due to the low weight of the cladding (16 times lighter than glass), the costs of the structural parts of the structure are reduced.
Design flaws made of polycarbonate:
- the ends of the coating should not be left open, as moisture and insects can penetrate into the cells, as a result of which mold and mildew will form and deterioration of the operational properties of the material and the entire mini-greenhouse;
- it is necessary to clean the sheets from accumulations of dust and dirt very carefully, using soft materials and neutral detergents;
- it is prohibited to use products containing salt, alkaline, ether and chloride components;
- it is impossible also use abrasive pastes and sharp objects to avoid damaging the UV coating.
Options for a mini greenhouse made of polycarbonate (see photo below):
What can be grown?
Polycarbonate mini construction excellent suitable for growing different types seedlings, undersized crops and even a small amount of vegetables.
Tomatoes, peppers, cabbage - seedlings of these plants can be grown in a reduced version of the greenhouse. It is also possible to grow early-ripening radishes, onions, dill, eggplants, beans.
When growing pepper do not plant sweet and bitter varieties together inside the structure, since in this case it will be difficult to avoid cross-pollination.
We build with our own hands
There are several options construction of a polycarbonate mini-greenhouse. Two possible models will be considered below.
Recessed mini greenhouse
The optimum temperature for the construction of a polycarbonate greenhouse is 10-12 ° C, since at temperatures exceeding this indicator, sheets of material increase in volume, and further with a decrease in temperature, they will decrease.
In-depth option greenhouses are characterized by a simple device and able to retain heat well, which is released during the debate of manure. The length of the structure can be any (within reason). As a rule, such structures are built no longer than three meters.
Width should be no more than 1.5 m... With a large width of a mini-greenhouse, it is inconvenient to work with it, while a structure of a small width is not able to accommodate the required amount of manure, as a result of which heating will be insufficient.
The level of the deepening depends on the conditions in which the structure will be used: for low temperatures optimal would be depth 80 cm, and when using a greenhouse during small cold weather, 30 cm will be enough.
Top filling of the pit - soil (layer thickness 20 cm), the rest is filled with manure.
The polycarbonate structure is installed on a log frame, which is mounted around the pit. For framing, logs with a diameter of 100-150 mm are used.
To protect wood from the effects of moisture withshould be treated with hot linseed oil or close the perimeter with pieces of old linoleum. The roof of a mini-greenhouse can have a different design: arched, one- or two-pitched. Here we will talk about a single-slope design.
The roof frame can be assembled from wooden beams. First, the side structural elements are knocked together or twisted with self-tapping screws, which are triangular-shaped parts (the bottom of the parts must correspond to the width of the pit).
Further, the finished "triangles" in the corners are fastened together with bars, the length of which is determined based on the length of the pit. The upper and lower bars should also be fastened together with 2-3 transverse strips.
The frame is ready. It remains to close it on all sides (except for the bottom) with pieces of polycarbonate, securing them with self-tapping screws, and glue the places where the sheets adhere to the tree with tape.
Hinged cover in this design not provided, therefore, during operation, the structure will need to be completely removed for a while.
Additionally, you can find out on our website how to build a greenhouse with your own hands: a foundation, a frame made of available materials, a profile pipe, how to cover a greenhouse, how to choose polycarbonate, what color, how to make vents, underfloor heating, an infrared heater, internal arrangement, and also about repair , winter care, preparation for the season and how to choose a ready-made greenhouse.
Mobile mini greenhouse
This is a practical and economical option for a compact greenhouse that retains heat as well as a recessed structure. Such a model can be use at stabilized temperature, in the second half of the spring season. Equipped with wheels, the mini-greenhouse can be easily moved around the site if necessary.
For the manufacture of DIY mini greenhouses made of polycarbonate, will need:
- support frame;
- four-wheeled device;
- plywood sheet for arranging the bottom;
- two bars with which the rafter legs will be attached;
- self-tapping screws.
To assemble the support frame, small thickness bars are used, which are fastened end-to-end with self-tapping screws. Wheels can be attached to stand legs... The side bars of the mini-greenhouse serve as a harness to which the rafter legs are attached.
At the top, a gable roof is mounted, which is assembled from frames equipped with polycarbonate, fixed with self-tapping screws.
From the ends construction worth equipping with hinged doorsso that you can ventilate the greenhouse. The bottom of the structure is covered with foil and covered with manure and soil.
Mini greenhouses made of polycarbonate - great alternative traditional glass options. The lightness and strength of the material, combined with the ease of assembly and installation during the construction of certain models, induce the choice in favor of polycarbonate structures.
