I have a 41qt tub with one 30-40gal UTH, medium sized crock water dish, two hides, etc. It currently has about 250 holes in it for ventilation. A thermometer I have outside the tank says it's 69% humidity. The Accurite inside the tub says 80%. When I add more holes, it goes down for a couple minutes, then creeps back up.

To male things worse, I'm going back to school in a month in Maryland, so I'm not sure if I'll have to change holes again. Any suggestions?
