I have a 30 gallon breeder critter cage that wasn't being used. I decided to split it up and put two young bps in it. Each side.of the enclosure will be 18lx18wx12h...I have blacked out all 3 sides of the tank and have plexiglass and foil waiting to be cut to size for the top. I did a quick experiment today and threw in some aspen a hide on the hot side and a water bowl. I cover most of the top and put a 100 watt bulb over the one side that had everything in it. The accurite said it's 84 on hot side and 78 on cold with humidity of 39%...could I use a larger uth (11x17) under the tank and split it right at the divider? I was thinking of that and then putting 2 lower watt heat lamps over the center/cool side to help raise ambient Temps and have water bowl under heat lamp to raise humidty. Does anyone think this will work or have any other suggestions on what's the best way to attack this. Thanks
