works perfectly with programmable thermostat

This mat is hands down the best answer for controlling the temperature in your grow!!

I am a beginner at medicinal mushroom growing and was looing for a way to keep my substrate warm. Throughout the whole colonize and fruiting process. This has done just that. Very user friendly, simple, and is keeping my substrate/monotub in the mid 70*F even with about 3" of substrate. *Only one side of this mat heats up so NO WORRIES about the surface its on getting hot!!

Highly recommend this to anyone who wants that extra bit of insurance for a succesful grow.

It makes a great incubator when put in a box .I put the pad in a cardboard box with the cord running through a hole than I put a plastic terrarium in on the pad it's been down close to 30 f and my incubator stay a constant 80 f out side in a shed .

Product came on time and packaged appropriately. Have not had time to use it yet as I'm waiting on some inoculation.
