The growth is stimulated and accelerated by the increase in temperature. Straightforward and safe technology ensures the best possible propagation success. Therefore, the required heating of the entire greenhouse is not necessary. Also for seed culturing frames and cold frames. At a room temperature of ~ +20 °C, the uncontrolled basic temperature is ~ +40 °C.
The thermostat H 80 (aftermarket equipment) may be used to keep the desired temperature at a constant level.
