I've never used cypress before but I know with Eco earth that we used to use you had to soak it, then squeeze as much moisture out of it and let it dry a bit before using....soaking wet sounds odd to me. Plus, if it's too wet that can lead to a too cold Snake which can lead to your BP burrowing onto the UTH if you have one.

Im pretty sure anything that is wet or completely damp is not good for a snake to sit on. If you are worried I would take the bedding out and dry it some and try a different way to add humidity.

Ive heard of people putting sphagnum moss in Dixie cups or the hide to create more humidity.
Whats the top of your enclosure?
