I've seen a number of different people say that humidity in the 40's is fine for a standard environment. Enough of them have large enough collections to give them at least some credibility in what they say. 50-60% isn't gospel truth. LOL


That being said though...whether you're talking about 40% or 60%...all I've ever seen or heard has been anecdotal evidence. I would be very, very interested in seeing some scientific studies on the matter, or even a detailed journal where a breeder (or just someone with a large enough collection) kept different sets of snakes at different humidity levels and recorded the resulting sheds and overall health of the animals.
