The Economy Soil Heating Cables are ideal for starting seeds. A built-in thermostat activates when the soil temperature falls below 74 degrees.
The thermostatically controlled heat of these electric soil warming cables gently speeds germination and seedling growth to produce large, healthy plants ready for transplanting. Use indoors or out to provide a head start to the regular growing season. GRO-QUICK cables come in a full range of easy-to-install sizes.
