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 GRO-QUICK 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.
