Hydrofarm™ Seedling Heat Mats

These Hydrofarm seedling heat mats have been reengineered for better performance and greater durability.

The new stronger heating wire, and thicker multilayer construction (50% thicker!) offer more uniform heating and the durability to withstand rugged greenhouse environments so they're tough enough for your home! Plus, the layers are heat-bonded (not glued!) to stay sealed year after year.

By providing bottom heat (up to 20°F above ambient air temperature), you'll increase the germination rate and success of your seedlings and cuttings. Plus, each mat has a handy seed germination guide for many popular flowers and vegetables. Choose from four sizes.
