I struggled with the same thing and I had the moss in the corners and on top of the hides. I would spray water twice a day and cover the top with a damp towel but still lost my humidity. I just stopped running the lamps as much and I stopped using the day time lamps altogether and just opened the blinds in the room. They are not near the windows but plenty of light got to them. I placed the water dish half way on top of the uth. The water that evaporated really made a difference for me.
