Living in the bay area and I do talk to Brian from time to time and I do the same thing as well. When the snake is in blue or in shed, he mists them with a spray bottle all over their body and then just leaves them alone. I do the same thing too and I keep my snakes in a rack system. I really don't focus on humidity that much either. I care about the hot spot for the snake, mites/sickness from the animal, and if the snake is eating or not. But this is just the area that I live in and the system that I have. I keep my snakes in a bit smaller tub where the water bowl is also their hide so the water bowl goes over the heat tape and creates some humidity, but I've never measured the humidity of the tubs and never will. Never had a bad shed, never had a sick snake, or a snake that go off food due to bad habitat.
