Kiegészítő megvilágítás használata téli magvetésekben

Together with the increasing amount of plants, usually there is less time for taking care of the germinations. Thus, winter can be the only season quiet enough for that. One can try germinating seeds in windows, but light windows are often used for overwintering other plants as well. In this situation, an old aquarium can be the resolution, the light source of which is replaced by compact fluorescent lamps. Though the system is closed, the compact lamps only increase the temperature to 24-26 °C that is optimal for germination as well. Humidity precipitates on the walls of the aquarium and the gathering water contributes to the optimal wetness of the soil in the pots. Under these conditions, the development of the seedlings of Lophophora diffusa, Astrophytum senile, Ferocactus cylindraceus (syn. F. acanthoides) and Cereus repandus (syn. C. peruvianus) is satisfying. Nevertheless the growth of the seedlings of Thelocactus conothelos (syn. T. saussierii) and Thelocactus buekii (syn. T. matudae) is disturbed. The energy usage of the two compact fluorescent lamps is only 7.2 kWh that means a negligible extra cost.
