When looped 4"-6" below the soil surface, this cable works like an underground sun to heat the soil and speed germination and seedling growth with gentle bottom heat. It works best in an enclosed, insulated, and covered planting box. Not designed to work in outdoor beds. A built-in thermostat automatically activates the cable when soil temperature drops below 74°F*. The cable plugs directly into 110V outlets and uses 42 watts/12 ft. It is designed to prevent shock danger in wet conditions.
*Please note: this does not mean that soil temperature will reach 74°F.
