On the wave of popularity of a healthy lifestyle and organic products, the question of the arrangement of a winter greenhouse becomes urgent. The ability to grow healthy food all year round, which need not be doubted, provides an abundance of modern thermal insulation materials.
Specialists call cellular polycarbonate the best raw material for building a winter greenhouse. The structure of the material passes 85% of the visible light - while it is filtered in such a way as to pass the rays of the soft spectrum necessary for photosynthesis of plants and to limit access to the hard ultraviolet spectrum.
Also, the advantage of polycarbonate over ordinary glass is that the light is dissipated before it enters the greenhouse, reflecting off the faces. Thanks to this, the illumination in a winter greenhouse made of polycarbonate will be uniform; the correct heat distribution will also be ensured.
The easiest way is to purchase a demountable greenhouse made of polycarbonate: the complete set includes a frame, sheets for covering, fastenings and instructions. Of course, it will be cheaper to mount the structure on its own - but you need to correctly assess your strengths and compare the savings with time spent on work. Those wishing to puzzle themselves with the independent construction of the winter greenhouse "from A to Z" should pay attention to photo and video master classes: visual aids always work more efficiently than the most detailed instructions.
For a winter energy-saving greenhouse, a wooden frame will do - in the event that the crop does not need high humidity (as, for example, for cucumbers). Then it will be necessary to use aluminum tubes for the core.
Choosing the type of construction of the greenhouse, please note: asymmetrical designs can be several times more efficient. Also common are greenhouse-extensions, it is mounted near the southern wall of the house, which needs to be painted in a dark color.
Very well-known are the so-called round greenhouses, the construction of which, in fact, is a polygon. The lack of such greenhouses - poor air circulation, therefore for them it is necessary to think carefully the ventilation system.
Of course, in order to grow plants in the winter, you need to think not only about the top lighting, but also on the heating of the ground: it is naive to believe that you will get the shoots from the frozen ground. In fact, the main difference between off-season greenhouses is the availability of the foundation and the basis for the design.
For the heating of winter greenhouses, it is necessary to excavate a pit, to the bottom of which the elements of the heat accumulator are laid (aluminum convectors are best used), pipes for its ventilation. On top of the heating appliances covered with PVC film - this will protect the system from hitting the ground, and also provide good conditions for the accumulation of humus.
By the way, for heating of winter greenhouses it is possible to use both separate boilers and boiler rooms, they are intended for heating of apartment houses.
However, it will be most convenient to purchase specialized devices for heating and ventilation of winter greenhouses. Their purchase will cost more than the independent installation of communications, but they will allow you to save significantly in spending on energy.
Inside the winter greenhouse, it is advisable to use heat-saving items: for example, dark slabs for tracks. From the north side it is necessary to attach sheets of foam plastic for better thermal insulation. Also for the equipment of a winter greenhouse additional lighting may be required: for a short winter light day, the plants will not receive the required amount of light. Considering all these moments, you will receive an excellent platform for growing vegetables in the winter.
