Help! I have a 10 gallon terrarium with a screen lid. I have coconut fiber and very wet moss, a swimming pool and misting all day but my humidity is still at desert on the gauge after 30 minutes of spraying. The local pet store said to ramp up my heat so my heat is at 80 but still no humidity. Plastic/ Can't use it because will catch fire. Will I need to make it more aquatic on the bottom or get a regular fish top. I have been trying everything for a week and very concerned.
