I started off with a glass tank but could not control the humidity and my bp had a bad shed. So I moved her to a plastic bin and I have been able to control the humidity really well. I have a digital hydrometer and the humidity stays between 65 and 80. I know that is a little on the high side, but I clean the bin out every day so I'm not worried about a respiratory infection. I have a heat pad set up with a thermostat which keeps the basking area between 90-93 degrees. I noticed she was going into a shed recently and I monitored the humidity even closer. I fed her 4 days ago during the first couple days of her eyes getting cloudy and she ate just fine. With all that being said, her shed was even worse than the first time. This is so aggravating, I just don't get what I'm doing wrong. One possibility that I think it could be is the fact that she is always in her hot side hide. She comes out at night snd slithers around quite a bit, but during the day she is always on the hot side. Maybe the pad is drying her out too much.
