Welcome to the wonderful world of maintaining a glass enclosure!

While maintaining your desired parameters is 100% doable with a glass tank, it requires a lot more work from you than a PVC enclosure would. What I did with my 40 gallon was tin foil and duct tape all over the top with the exception of where the CHE sits. A big water bowl directly under the CHE, and a smaller one on the cool end. I have a humid hide, and I mist a couple of times a day. All of this together keeps my humidity around 55-60%. I always let the enclosure kind of dry out overnight, which usually puts me around 52% in the morning, and then I just start the process over. This of course would be impossible to do if I wasn't working from home, and I'd end up having to get a mister on a timer or something.

It takes some work but it's doable.
