The frost-free greenhouse for safe plant growth
Anyone who wants to tackle the cultivation of vegetables, exotic fruits, orchids or tropical plants professionally, can not help but get his greenhouse frost-free over the winter. Which heating is the most appropriate, depends on the breeding goals, as well as the financial budget.

Noiseless and without exhaust fumes, a greenhouse can become frost-free by laying heat cables or electrical heating loops in a layer of soil underneath the plants. The operating principle is similar to the underfloor heating in residential buildings, which can be precisely controlled via a temperature controller, as possible optimal heat values with minimum energy input to ensure.
