My home stays at 68. I have two tanks in my living room as displays and one is a 40 gallon for my ball. I use a 100 watt che on the warm side and a dual fixture with a day and night 60 watt bulb on a timer for the cool side to keep my eminent temps right. I also use a uth.

With humid hides I still have great sheds.

My che and bulbs are not on a dimmer or tstat. I use the ZooMed lamp stands to give the correct distance needed to give me a good surface temp and good ambient temp.
