Since moving my bp to a tub with a sealed lid(not one with vent holes) the humidity has been a big problem! We soldered about 30 holes along each side of the tub and on the top but even without misting the tub spikes up to 70-80% on a daily basis. It's so humid water clings to each side of the tub! I use aspen bedding. Any suggestions for how to help this?
