Humidity issue concerning cornsnake

[Black_Shark]

Got a question.

I have my 2010 cornsnake in my 3 41q tub rack in a 16 quarter with the lid on the top. Everything has been going great but the humidity wont go below 80%! If I take the top off, he manages t get out, even with cardboard, etc to make the tub lid flush with the top. This is because of the gap in the middle where the handles go (yes they are still attached and he still gets out). There is no moisture in the tub, no condensation on the sides and it feels dry in there. What do you guys/gals think? Will this cause issues?

Have you drilled holes in the lid? SOmetimes you have to add more holes. Also, you can use binder clips around the lid to keep him from getting out.
