The temp of my herp room runs in the mid 70s in the summer and the mid 60s in the winter.
Currently, I give them a hotspot that hovers around 88 degrees. It's belly heat in the form of 11" flexwatt. I currently keep all my drys in FB racks - the 66"x30" giant drawers. Old school with the 100% ventilation tops.
I've used cages in the past, but have found no issue with the giant racks. They key is to give them several hides, logs, and even length of corrugated pipe to explore.
They will use the heat when digesting meals - sometimes. In the past I have gone years without giving them supplemental heat.
I don't have a wait list. If they lock up and the females lay, I'll shoot you a PM. I'm pretty relaxed about these things............
