Well here is the cage info:
4'x2'x2' custom plywood cage stained and sealed. Glass sliding doors. Ceramic tile floor grouted and sealed. This was a Beardie cage before I converted it. I am using a CHE as the heat source. Fluorescent light on 12 hour cycle. Deep blue LED lights for night viewing. Naturalistic setup with two appropriate hides and lots of decor. I chose cypress to battle humidity. Herpstat 1 for my tstat. Temps are 92-80 surface and 86-80(83) for ambient.

My concern is I sealed part of the large vents and now I don't even have to mist but my humidity is 70-74 for the last 5 days. Now I did have pretty heavily misted

My question is about substrate. I love the look of cypress and it doesn't mild easily. I just don't want too mic humidity because that could be a problem. I know I could open the vents up a bit but don't really want to waste heating energy.

Any thoughts appreciated.
Thanks
