I have had a bearded dragon for a few weeks now, so far everything is going well, except for the hot side humidity. It is a 120 gallon enclosure, the hot side ambient is 85, the cool side ambient is 80, the basking spot is 105, and the cool side humidity is in the lower 30s. The hot side ambient however is stuck in the upper 20s no matter what I do. Is an upper 20s humidity dangerous to bearded dragons?
