greenhouse soil heating

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

Main advantages:

  • 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.
