I agree with Kaorte 2 bowls don't do much for humidity I use it to keep the hides staying put. The rooms humidity will be the biggest issue. In my case the general room humidity is usually sub 20% in the winter the summer it goes up to the 50% range. I have loads of issues during the winter the summer I almost don't need to do much. Set up your enclosure water in the bowl(s) and see what you get after a few days then try one bowl wait and see. Keep trying this or that to see what works for me the moss I tried dried out super fast and didn't really make much of a difference so I used the rocks that are much slower to dry out in the extra low conditions I have that worked for me it may or not work for you. Test things out before you add a snake, things have odd effects sometimes I found that when I got the humidity right the temps tanked on me I kept tweeking things until it balanced out a bit of patience now will save stress for you and the snake later!
