Electra Grow Mat Small

Protect delicate seedlings from fluctuating temperatures with these grow mats. The thermostatically controlled rubber mat provides safe, uniform gentle heat by raising the soil temperature by 10-15 degrees for maximum germination. A solid wire support encloses the mat where the seedling trays are placed, allowing the heat to rise and give the proper air circulation. Minimal amount of electricity(90 watts) is used and it delivers exceptional results when used with florescent lights. 21 IN X 15 1/4 IN
