I have researched this topic on this board and others but all I can find is above misting and live plants which I already have both of. I recently completed my tree frog enclosure and have been cycling light every 12 hours. The tank is misted twice a day and has live plants and a small water feature but the humidity won't rise above 68%.

I plan on having clown frogs which need 70-80% any ideas how I can increase my humidity.
