My enclosures are 50 gallon glass. I have lamps and uth and my temp and humidity is fine. I use paper towels as a substrate and I change it weekly (to prevent mold). I also have 50% of the top covered in paper towels that I mist as well. I only have to mist every 48 hours (give or take 12 hours) and the humidity stays in the 60-80% range.
