Redi-Heat heavy-duty plant propagation mats from Phytotronics supply steady heat to the bottom of flats and pots to help germination. Easy to install and economical. The propagation mat includes a 5’L cord and 120V AC plug. Each mat can heat the soil temperature up to 20°F over ambient temperatures (other heat sources may be necessary if the growing area is too cold). Mats provide more heat toward the center of the mat and are cooler towards the edges.
NOTE: Must be used with a thermostat (sold separately, Item # 227578). Failure to use a thermostat voids the warranty.
