By extending the growing season, this system allows you to double the yield in the greenhouse! You can plant earlier in spring and later end the season in autumn! Reliable protection against frost and unfavorable summer weather! A high-quality thought-out system from a Russian manufacturer! The principle of operation of the heating system is to maintain a constant soil temperature by supplying and removing the supply voltage to the fuel elements - a resistive heating cable, which is installed in the soil layer under the root system of plants. Temperature control is carried out using an electronic thermostat, which measures the temperature using a sensor installed in the heated soil layer.
