Baird's humidity levels?

[chinupcheerup]

I have a newly acquired Baird's ratsnake, my first snake. I got him from a pet store who knew little about him and wanted to get rid of him, since he was an escape artist (they had him in a small critter carrier and he is almost 2 feet long, I would escape too!). The only thing they could tell me about him is that he needed low humidity so he would not develop respiratory infections.
I have searched the internet, and can't find any specific info about humidity for Baird's. Some places say just like corns, some say low, and the book I have says 55-60% with as little variance as possible, which is not low in my book.
I know I have seen some of you here have Baird's, what humidity levels do you keep them at? He is at 40% right now, which is my best compromise between "low" and "just like corns". Because he was in a pet store, I worry about his health. I don't think he is sick right now, no mouth gaping wide open, bubbles, rasping, or anything (he does open his mouth a bit every once in a while, I am chalking it up to him being in a new place and not knowing what to do).


(And just because I am a proud snake mama, I am attaching a picture of him)

Future Baird's Owners: This is what I have found out.

Killian saw the vet today (who owns her own Baird's!), who told me that his humidity should be at about 50% and his temps should be 90-95 on the warm side and not lower than 75 on the cold, closer to 80 is better. They also do well with once a week soakings, especially when the humidity outside is low like it is here in the winter.
