What determines germination is not the temperature of the greenhouse air but that of the compost the seed sits in. Even when the greenhouse air is at 15 °C, the compost often stays at 10–14 °C; at that temperature peppers and aubergines either do not germinate at all or germination is spread over 15–20 days. Both solutions here heat the root zone from below; heating the root rather than the air lowers the energy cost.
Laid on the base of your existing sapling, rooting or plug-tray bench; it heats the root zone from the bench floor, beneath the trays or beneath the soil. It is made to the dimensions of your bench. The price is for 1 m²; the controller is not included and is selected separately according to the size of the project.
A galvanised frame, galvanised sheet top and TMax heating cable laid into the base come as a single product. The standard size is 1 m × 2 m with a height of 96 cm. It is modular: benches are added side by side to build a run of any length. The three-mode digital panel lets you run different benches in the same greenhouse at different temperatures.
