The Super Sprouter Seedling Heat Mat will help you have better success rates with seedlings and cuttings. Using only 20 watts of energy, it gently warms root areas approximately 10-20 degrees Fahrenheit over ambient temperature to improve the germination and rooting process. Heavy-duty construction makes this mat very durable. Because it's more than 20% larger than competitive mats, it produces even warming of an entire standard 10-inch by 20-inch tray. You'll discover it provides more consistent heating with fewer hot spots than other seedling heat mats. Measures 10-inches by 21-inches.
