A little information before I ask my question. I have an 18x18x24 exo terra enclosure, the tank has 2 sheets of glass resting on the screen top to hold in moisture with about an inch on an end on both sides for a cross breeze. On the back and top of which i have a hood that has 2 26w bulbs for my plants. I plan on getting some leucs 3 or 4. my temp range is between 72-80F on a daily basis never over 80 for long though. My substrate from the top down: spaghnum moss> eco earth >mesh stuff>hydoballs. I water/mist my plants twice daily for 20seconds and then have a humidifier/mister turn on for 10mins 6 times daily.

Okay question time... I can't seem to get my humidity to stay up! I can get it to hover around the 90-92% for about an hour and then I find it drops back down to 78-85% most of the time. I've looked everywhere for an answer and have not a clue where I'm going wrong. would a photo help? Any advice would help me please and thank you!
