Root Radiance Heat Mat - 48 x 20.75-in - 105W - 120V

Steady Root-Zone Warmth for Seed Starting - 48 x 20.75 in

Cool propagation spaces slow germination and leave cuttings slow to root. The Root Radiance Heat Mat warms the root area by 10 to 20 degrees over ambient temperature, so seedlings and cuttings start in more consistent conditions. It is built to be durable and water resistant for damp propagation areas.

This large mat covers four 10 x 20-in propagation trays at once. That makes it a practical fit for regular indoor growers, nurseries and greenhouse benches running several trays together, rather than a single small tray.

Key Features & Benefits

• 10 to 20 degree rise over ambient — gives the root zone gentle warmth to support germination and rooting.

Who Should Use Root Radiance Heat Mat
