Hey, i'm a newb but I saw you got no answers yet so I thought I'd add my two cents in...
I started off my setup with a uth (heat pad) under the hot side and a nocturnal red heat lamp on a dimmer on my cool side. I needed a heat source on the cool side because my house is kept way to cold to maintain the proper cool side temps. That setup worked great for the temps but the lamp was killing my humidity.
So yesterday I just went out and got one of the zoo med mini uth's for my cool side. I got rid of the lamp all together and now I just have a large uth under the hot side on a thermostat and a mini uth for the cool side on a rheostat. So far its working well. Hope this helps!
