What is the correct humidity?

Well I'm no expert by a long shot, but my experience is that 60% to 70% is perfect!!!

Okay, Thanks.

I keep mine around 60%, why? Because I am successful at the level. If you are successful at 70%, then go for it. Just be sure that the actual surfaces in the enclosure are relatively dry, not damp. The reason for this is bacteria growth. Bacteria growth can lead to infections or irritate an on-coming infection.

My bp had mouth rot when I brought him home and I had to give him injections for a month to rid him of the infection. For me, that is a big reason I don't up my humidity more than 60%. That is a personal choice and like I said, if you are successful using your technique, then why change what works?

I keep my tubs at 50-55%; some snakes I need to make sure I bump humidity during shed and other snakes shed fine without the bump in humidity.
