Which soil heating in a greenhouse is better cable or film with infrared radiation
For heating the soil in greenhouses, an infrared film heat-insulated floor is considered an ideal option. Its electromagnetic field is 10 times smaller than that of a TV, therefore it is harmless to vegetation. But here it is important to install it correctly. Since it heats from 2 sides, mandatory thermal insulation from below is required so that the heat does not go into the ground in vain. From above, the warm floor is necessarily covered with a greenhouse film of about 100-120 microns and only then there is a layer of soil about 30-40 cm, no less. Do not forget to install the thermostat with the floor sensor so that you can freely control the temperature of the soil and save energy.
