It depends on the needs of your animals and plants. The geckos I have that need misting (crested geckos, gargoyles, a leachianus and a few day gecko species) need it humid but not soaking. I mist the nocturnal geckos in the evenings and the day geckos in the mornings. For these species I mist once a day. Once you know how much moisture your plants and animals need you can figure it out (and Mist King may be able to provide some suggestions if necessary).
