Re-engineered for better performance and greater durability. The new, stronger heating wire and thicker multi-layer construction offer more uniform heating and the durability to withstand rugged greenhouse environments.
Warms root area approximately 10 to 20 deg F over ambient temperature to improve germination process. Helps gardeners have better success rates with seedlings and cuttings. Perfect for one standard 10 in x 20 in propagation tray. Heavy-duty construction makes this mat very durable. More than 20% larger than competitive mats. This allows even warming of your entire tray. More consistent heating with fewer hot spots than other seedling heat mats. Ed Hume seal of approval.
