I keep my temps at 90-92 on the warm side for my boa. They also require much more space. My current one is about 3.5' and she's in a 40 breeder. She won't be staying in it much longer. I keep humidity around 60%. Being such a big tank, I have two UTHs. The second is set to 80 F and the water bowl sits on top of that...gives it a nice constant 60% humidity. I also have the top foiled off, except of about an inch strip on both sides of the lid. Both UTHs are on rheostats.
