Honestly, it really is quite a hastle to keep the humidity where it needs to be in a glass tank with a mesh top. I just switched to tubs myself. I'm sooo glad I did. The humidity stays EXACTLY where it needs to be. The heating was kinda tricky because tubs don't hold heat as well. But, I experimented around for a bit, and once I had everything stabilized, it took out A LOT of the work that I was previously doing when I had a tank.
