Add this strong, robust, flexible cable to soil in a raised bed outdoors, in a greenhouse or a large cold frame and it will heat the soil or sharp sand for optimum root development for all your plants.
The ideal way to propagate seeds and cuttings for strong, healthy young plants which will flower more freely and produce fruit and vegetables earlier in the season.
Lay the cable in a snake-like run of rows set 7.5-10cm (3-4 in) apart on 5cm (2in) of horticultural sharp sand. This layout will allow soil temperature to rise by 11-13° C (52-55°F) with a greenhouse temperature of 7°C (45°F).
You can achieve higher temperatures by laying rows closer together. Just add a thermostat to the soil to ensure the correct temperature range for your growing seedlings and young plants.
