Fast-Gro Propagation Mats

Fast-Gro bottom heating propagation mats keep soil warm to aid in indoor germination and prevent rotting when soil temperature drops below 60 degrees Fahrenheit. Temperatures remain 15 to 20 degrees above room temperature, while using less than 10 cents per day of electricity (no thermostat required). The flexible heater mat is hermetically sealed in plastic and comes with a five foot long power cord. Available in three sizes; a windowsill mat, 11" x 24", and 22" x 44".
