Good Morning BP.net

So I built my DIY snake rack last weekend and placed my 2 BPs in it the other night! I get great warm side and cool side temps, but my humidity level is staying high! This mornin it was up to 83%...I have 10 holes on the front of the bin and about the same on the sides, what more can I do to get the proper humidity levels?

(Also...when I can Im gunna post pics of the DIY Snake Rack..it turned out awesome!)

Thanks!
