Oh and also are Rev's sheds coming off in one nice long piece, or at least close to it? If it's coming off in pieces then the humidity would definitely be off by a least a little bit.
Even through the growth spurts with my girl all of her sheds came off in one perfect single piece, including eye caps and all.
I've been collecting them to keep something of a growth record hehe, and it's fun to have a 6' snake shed hanging on my cubicle at work for other people to see and freak out about.
