Mike,
I know a lot of people just heat the whole room...and I wish I could, but I keep my reptiles in the finished part of my basement, which is about 500 square feet...that's also where my office is located, so between having website clients over and being such a large room, I can't really heat the entire room to 78 degrees.
I only have four ciliatus (housed in two different cages), so I guess I'll just see how it goes (for now) with a 50 watt bulb on one and a 40 watt on the other.
This sucks because I have tons of rack space, but all of the racks house various boids, so none of my thermostats are set below 90. Oh well...I'm starting to get into Trans Pecos Ratsnakes too, so over the next few months, I guess I'll just set up a stack of lower temp cages on the opposite end of the room, specifically for Rhacs and Colubrids.
Thanks for the input. It's much appreciated.
