i try to keep humidity between 60 to 90 for my young panther, it will spike way up after misting, dont be to worried about that. you also want the cage to dry up buy evening so dont mist too late in the day
i run it for 1min 5 times a day( 8am, 10am, 2pm, 4pm, 6pm ) with a 2min spray at noon every day
