Hey there,
As far as the paper towels go, do you mean they are staying wet for days? From that info I gather that you don't have a drainage system in place, and so the water has no way of escaping to allow evaporation. My only concern with that is the risk of bacteria building up. I always allow my enclosures to dry out completely before misting again, and that is one of the reasons. Maybe consider setting up something simple soon?
