Sounds weird since most people have issues with not enough humidity (and the reason I have switched to tubs) but now I'm having the problem of too much humidity. I've made holes in the lid over the water dish; no help. Any suggesstions? I'm reluctant to buy a dehumidifier if I really dont need to. with the lid on its averaging 70-80% which is insane. So if I'm home I will leave the lid off (and watch him closely of course) and it will drop down to 55-60% which is my goal.
