All right, here me out on this one- this question will probably make everyone roll their eyes, but bear with me: I've read that American Green Tree frogs need no less than 65% humidity. With other frogs I read about it says they need 50%, 70%, whatever.... But what does that exactly mean? How does one measure the percentage of humidity? I mist my American Green Tree frogs' cage thouroughly at least three times a day, including mornings and evenings. Is that enough? I just don't understand what it means to put a percentage on humidity and how that translates into misting.
