Our Elixir Soil Warming cable is the ideal way to propagate seeds and cuttings on a greenhouse bench or in a cold frame. The soil in the greenhouse takes time to warm up naturally; with a warming cable you are able to plant earlier and raise better specimens

A simple frame can be constructed from wood and lined with polythene to form the propagating area. The cable is then laid onto a 5cm bed of sharp sand (horticultural) and covered with a further 5cm of sand.

They are water and moisture resistant which makes them ideal for use with indoor propagators. The soil cables provide constant heat and so the temperature of the soil should be constantly monitored & controlled by a thermostat.

Our cables come in various sizes and wattage.


Do Not use if the cable is broken, creased or cut.
