Im thinking of possible ways to keep my tank at the right temps during the winter (new place doesnt have free heat so it won't be like 80 in the apt anymore). I was wondering can I basically cover the entire bottom of the cage with flexwatt? I could have one strip for the hot side at 95, and have the rest of the strips set at 80. I figure with this I wont have to be as worried about the ambient temp, although I will still keep an eye on that as well.
