The main ways of heating the soil in the greenhouse and its features
The main purpose of heating the soil in the greenhouse is to grow different crops irrespective to the time of the year. Either to enjoy fresh fruits, vegetables and greens all time around the year or receive income from sale of grown plants. If you want to be able to grow your favorite parsley, cucumber or tomatoes even in the most severe frosts you need to have ideal microclimate that can be achieved by heating the soil.
Why it is necessary to heat the soil
- growing of crops in short and very accelerated terms;
- the ability to make thermoregulation with which you can grow a variety of crops that require very specific microclimate;
- growing seedlings in winter season;
- since the heating of the soil has a high efficiency then it makes sense to save considerably on waste of electricity;
- small bactericidal effect;
- the duration of the time getting the harvest increases.
Everyone can warm the soil in his own greenhouse. This type of greenhouse heating is cheap. You do not need to use additional ventilation because the ground is heated without burning out oxygen in the greenhouse. That is why soil heating save a lot of your money and resources.
Types of heating the soil
There are several types of this heating:
- the water type of heating;
- electrical heating;
- the biological heating (bio-heating).
Bio-heating today is the most economical way of heating the costs of which can be covered by any owner of a greenhouse. The heating of the soil in the greenhouse can be done by any improvised biomaterial: manure, sawdust, bird droppings, woody leaves. Each type of these materials with natural decomposition can release a certain amount of heat. So, this heating method is an ideal option because with its help it is possible to grow various plants at the optimal temperature and also to use this material as a fertilizer.
If you want to get the maximum effect, you must steam the material before usage. Steam it until the steam comes out. The right way to do this is to use boiling water, sunlight or treat the material with quicklime.
Electric heating. At this moment electric heating has a wide popularity. Synthetic materials for electric soil heat is produced in large quantities and has a small cost. The soil is heated by heating cables, mats, films and other materials.
The only one drawback of this system is the expensive use because of the price of electricity. To heat the greenhouse with this method requires a large expenditure of resources which means that it will be necessary to pay large bills every month.
The water heating method. The simplest and most understandable way of heating of the greenhouse and soil is the water type heating. The structure of water heating method is pretty much the same as construction of the warm floor. The hot water circulates through the plastic pipes which are laid in the soil and produces heating.
The water heating system is economical in terms of material selection. But the installation of this system can be time consuming. This method of heating is best if the greenhouse has large dimensions and also if it is situated in the immediate vicinity of the residential building. This heating is suitable for greenhouses.
