Hydrofarm Seedling Heat Mats - Attention!
Just a request for a caution. My first heat mat's thermostat failed to keep the temperature within the 85F limit. It also developed a single, hot to the touch, buldge on it's surface. Second mat, a replacement, although kept my tomato plants from cooking, developed the same nasty "melt down" buldge on the top surface and burned through the bottom, scorching the wood floor underneath. I notified the Hydrofarm company regarding this potential fire hazard problem but so far there has been no response. Beaware!
