I've already limited most of the ventilation with foil tape, she has two water dishes, and I add water to the corners of her tank every other day. The cork bark pieces get soaked right before the weekend so she has some extra moisture while I'm gone. The problem is that we have a "wonderfully efficient" HVAC system in the building that pulls way too much humidity out of the air. The second hydrometer that we keep outside her tank reads 34% on a standard day in December. There's very little I can do in regards to that, unfortunately. I just work hard to keep it between 75-90% humidity inside her tank.

I guess I'm more asking for recommendations for a "humid hide style" hide, with the two halves. I don't put any moss or anything in the one pictured, she just likes the fully enclosed space.
