Windowsill Heat Mat

The Windowsill Heat Mat increases growing success by warming plant roots and maintaining a controlled temperature all season long. It warms the root area 10–20°F above ambient temperature, so it works even in drafty spots, and its size is perfect for small growing spaces. Great for veteran growers, beginners, and children alike.

How It Works

Plug the mat into a wall outlet and it gently warms to about 10–20°F above the ambient temperature. Set a planter on the mat and the root area is gently warmed from underneath, improving germination. Do not allow the heat mat to sit on or near standing water.
