OK, so i just ordered a 3x2x15" PVC cage from boamaster (didn't want to wait 3+ months from AP). I got a 40 watt RHP and 24" flourescent light fixture. My question is, should i use flexwatt or not? Do I need to provide belly heat if the rhp is maintaining the hot side temp? I have her in a tub right now, with a CHE and flexwatt. It takes both to get enough heat without dropping the humidity. I am wondering if I need the flxwatt, or if putting something for her to hang out on that is warmed by the RHP, like a piece of slate, would be ok?
