I just built a rack and left enough space for adjustable heat lamps to be placed on top of each tub. That way I can turn it up just enough to give them a warm spot when it gets cooler. BUT I had 4 of them just laying around so...I'm not sure how you would hook up the thermostat..I think it would want to heat the whole garage. I find it worth it to breed. Shipping kills me on FT, while I can get bedding and food for a fraction of the cost of FT.
