The Agritape Heat Mat is a rollable 20-watt mat that distributes gentle bottom heat evenly throughout the surface area -- no "cold spots" as in the old days of coil heating. Plug it into the wall, place the ground screen on top of it to ground the current and protect the mat, and use it either with your own thermostat or without one. (If you do not have a heat mat thermostat, we offer the Precise Heat Thermostat.) This heat mat will warm the soil up to 20 degrees above room temperature, easily meeting the needs even of tropicals and seeds that require very warm conditions for germination.
This heat mat won't harm finish or paint, is very energy efficient, and is waterproof. Wipe it clean and roll it or lie it flat for storage; it will last for years! Perfect beneath your Bio Domes for starting seeds, or beneath any seed flats or potted plants. Measuring 22 inches wide and 4 feet long, it comfortably accommodates 6 Bio Domes. We also have a smaller size mat, as well as a all-in-one heat mat and thermostat.
Take the guesswork out of starting seeds and overwintering your precious plants. With the Agritape heat mat, it's always just the right temperature!
