Seedling Heat Mat 20 X 20

Used by experienced gardeners to provide bottom heat for faster germination of seeds and stronger growth of seedlings. Jump start spring by germinating slow growing plants early on your porch, basement or in the garage. Roll the heavy gauge vinyl mat out on a flat surface, plug it in to a standard outlet and place your seed tray directly on top. Direct contact means no loss of heat. Built-in thermostat keeps temperature 10º to 20ºF above room temperature to a maximum of 85ºF. UL approved. Holds 2 seed starting trays.
