Hi --

I am working on figuring how things are going to be set-up in my new cage. I built one out of wood, it has a plexiglass door on the front, and the bottom is plexiglass so I can attach a UTH. I am planning on insulating the bottom of the cage with aluminum insulation (ie -- plexiglass, uth, aluminum).

I live in MN, and our house is usually about 70 degrees (maybe warmer in the summer if the A/C isn't on). So, my question is, do I need one or two uth's??? I was thinking maybe having two -- one set at about 90, and the other at 80. Is this neccessary, or could I just use one and have it set at 90? I figure if I can get by with one, that would save quite a bit of money.

Thanks,
