Hydrofarm’s windowsill heat mat is perfect for veteran growers, beginners, and children too.
It is the perfect size for small growing spaces, and improves germination by warming the root area 10-20°F over ambient temperature.
By warming the roots, you increase your growing success, as this mat will maintain a controlled temperature all season long.
If you ever dreamed of growing a windowsill container garden but found the area just a bit too drafty, add this heat mat and you’ll be ready to get growing.
