Better safe then sorry I feel. Isn't keeping a BP in high humidity all the time bad for them as well though? My kids usually sit as 50-60% when not in shed and get boosted up to 70-80%when a shed is coming on. I have them on plain old aspen which I know some people have trouble with humidity wise but I don't ever seem to have a problem. I do have to do general misting a little more often during the winter when the heat is on in the house, but that's like once a week instead of once every other week.
