What should the air temp be on the cool side of my enclosure? I've currently got a thermometer probe hanging down and it's averaging 80F day and night (heat provided by red light on dimming stat) The temp (measured with temp gun) on the floor above the heat mat in her warm hide is currently 90F and the floor temp in her cool hide is 78F. The reason I ask is I've just had to change the setup as I was noticing a marked difference in day and night temps (due to a change in heating in my house) which is why I now have the red bulb so it can provide night heat too.
