The fogger is not always on, I fog it up for a half hour to an hour till the humidity raised to 70% and turn it off, by the next morning it's down to 55% and I repeat the process, it's good for simulating morning dew

As for the two hides, I'm getting them for the 40 breeder, actually I'm getting 3, because I do plan on putting both a mojave and pastel together... So I do believe that answers both issues
