I am having trouble keeping humidity up in my new T8. I have added moss, wash cloths and sprayed cages. Still dropping to 40's and 50's. Currently 46% in one cage and 50% in the other. Rocky is in shed and for the first time I have had them....I am worried about a one piece shed. I am using flexwatt belly heat and RHP for heat. I have a fan on in my room, do I just need to turn it off? Any suggestions?
