Windowsill Heat Mat

How the Windowsill Heat Mat Works:

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.

Do not allow the heat mat to sit on or near standing water. The Windowsill Heat Mat works by plugging into a wall outlet and gently warming to about ten to twenty degrees above the ambient temperature. When you set a planter on the heat mat, the root area in the soil will be gently warmed from underneath.
