GC1 Gro-Control Thermostat
Vendor: PRO GROW SUPPLY CORP
*Accommodates 2 mats - range 40 to 100
You can use any open space for a propagation area. The mat is light enough to put on counters, and tough enough to use on any concrete or dirt floor or growing area. It is so rugged it will last for years, and its sturdy, molded construction makes it completely waterproof and impervious to soil, chemicals and fertilizers. Just roll out your mat and plug it in. There are no wires to tangle, no concrete to pour. It's ready to go at once.
