A Parasene 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 soil warming cable you are able to plant earlier and raise better specimens.

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

Cable is laid in runs 7.5-10cm apart. This layout will allow you to raise the soil temperature by 11-13deg.C, assuming a greenhouse temperature of 7deg.C. Higher temperatures can be achieved by laying the cable runs as close together as 5cm. In this case a Parasene thermostat should be used to precisely control the soil temperature meeting the differing germination requirements of various varieties of seeds.

The Parasene Soil Warming Cable - 20 feet is 10 feet long (3.05 metres) and will cover an approximate area of 4 square feet (0.45 metres).

The Parasene Soil Warming Cable - 80 feet is 80 feet long (24.4 metres) and will cover an approximate area of 36 square feet (3.85 metres).
