A couple inches of drainage layer, some mesh on top, substrate above the mesh. Really, so long as you reach your goals in the burrows/hides where your youngster is going to spend at least half of their time, you'll be fine.

A closed chamber sounds good for hitting humidity levels easily but terrible for everything else. I've always been a fan of high air exchange though and try to reach my goals with as much ventilation as possible. I'm in Florida though, everything humidity related is much less hassle here. If I lived in CO I'd probably turn my reptile room into a jungle with a bunch of water loving houseplants to help raise the ambient humidity in that room, then go from there.
Ah yes, in a warm humid climate like Florida things get a lot easier. Cold and dry CO makes it difficult. My closed chamber has some minimal ventilation, and has full air exchange daily during feeding time.
