Hahaha its ok, nothing bad will happen, you dont have to do it anymore tho. As long as he has water he'll be ok. You can buy sphagnum moss, place it around the enclosure and make it moist. You can also put a damp towel on the top of the enclosure (i think you have screen top right? If so, the humidity escapes through there) dont cover the whole thing tho, let space for air to go in, an open the top at least once a day to get "new" air in. Any of those two methods will increase humidity, but for now i would say use the towel and see if it boosts the humidity.
