Sounds like you may be getting some bogus information on just how much humidity you need to provide. I live in the good 'ol Midwest where winter dryness is a real problem for captive boas/pythons, however, I have never experienced too many problems associated with the dry, winter air. My cages are misted heavily every other day and a large water pan is available at all times. Some of my exhibit cages do have pro product misting systems which have been absolutely wonderful but not all of them have these technological advances. I have found that as long as I provide intermittent high humidity along with a daily heavy misting during shed cycles, I don't have any problems whatsoever (and NOT ONE of my burms, who some are in their 20's/30's, have never seen a water container larger than their water bowl....I've never given them a bath and in some ways, the many toxins that are found in tap water are probably harmful in the long run if used too much for soaking). One of the keys that I think people fail to realize is that RI is not just due to inadequate temps and humidity levels but also PROPER SPACE. To put a large burm in a small cage w/little time to stretch out is not a good situation; even for a sedentary animal like a burm. My large burm, 18' ) has a 12' x 4' cage and even that, in my opinion, is too small but for now, works well since this snake comes out for regular interaction and stretch time. My other burms that are 10-16' are kept in 8' x 3' cages.
