I've researched this question until I'm ready to explode. I can't find answers that are even CLOSE to the same. I've hit all the major sights from all the major search engines and am done with that. My tank is finally set up perfect as far as temp. zones and basking area and hide spots and I'm getting a lot of activity from my Ball (he seems to really "enjoy" the whole environment)...I just don't know what the proper (and/or healthy) humidity level should be. I'm willing to go with the "general consensus" if I can just get enough similar responses.
