The Bio Green warming pad is a plug-in unit that makes propagation easy. The warming pad produces even heat, ideal for excellent germination results. The waterproof warming pad is ideal for raising the soil temperature around the roots by approx. 5-10°C above ambient temperature. This means excellent results can be achieved even in cooler places. It is also suitable for propagating from cuttings or encouraging sensitive plants such as Orchids. To achieve the best conditions for growth, we recommend the TER 2/GB thermostat with remotesensor as an extra. This makes it really easy to set the ideal temperature for different types of seeds, to the exact degree. To save energy it is worth laying a polystyrene sheet or similar under the warming pad.
