Maximum Germination Kit | Soil Heating Cable, Thermostat & Propagator Combo

Create a warm bed for your seedlings

Give seeds, seedlings and young plants a warmer start with the Elixir Gardens Soil Warming Kit. Designed to create gentle, consistent warmth beneath propagators and seed trays, the kit provides a practical way to build your own heated propagation bed in a greenhouse, polytunnel, shed or other suitable growing area. The system works by laying the soil warming cable inside a shallow bed of damp sharp sand or damp compost. The cable gently warms the surrounding material, which distributes the heat beneath the propagators placed on top. This creates a warmer root-zone environment that can help encourage germination and early plant development when ambient temperatures are too cool.

Versatile

Construct a shallow wooden frame to suit your available growing space, line the inside with plastic, and add a base layer of damp sharp sand. Lay the warming cable evenly through the bed without allowing the cable to cross or overlap, then cover it with another layer of damp sand before positioning your propagators or seed trays on top. The size of the bed can be adapted to suit your setup, making the system suitable for anything from a compact propagation area to a much longer greenhouse bench. The Soil Warming Kit is suitable for seed germination, early propagation, seedlings, cuttings and young plants, particularly during cooler periods when additional bottom heat can help maintain a more favourable growing environment. It is an excellent option for gardeners wanting to create a custom heated propagation bench or soil warming bed without relying on multiple individual electrically heated propagators.
