Humidity Box or Not?

[twentyeggs]

Hey guys I have a King and Corn snake. They are both babies. I've had my corn snake through 4 sheds now, and my king through 1. It was my corn snakes 3rd shed that I noticed she left a small patch of skin towards the end of her body. So when they both conveniently blued up around the same time, I made two humidity boxes. I tried to put them in the boxes and at first they fought like hell to squirm out of the hole. So I gave up trying to "introduce" them to it and left it in their cage. It took 2 days but they both decided they love the humidity box. In fact it even changed my corn snakes shedding cycle. Normally she sheds within 3 days of turning blue, 24 hours of clearing up. But this time she stayed in that box for almost 5 days after clearing up. My King Snake also took her time. They both returned to the humidity box after shedding.

So my question is should I make a permanent Humidity box for them? My concern, especially for the California King and living in Southern California myself, It's not really her native environment to live in a box of wet paper towels/moss. I don't want to experience any dermatological problems that come with constant exposure to the 6 senses sensational slither spa. They both have a water bowel that I always leave in there and keep full. What should I do?
