One thing I noticed from your pictures is the screen tops. Screen material is so fine that it filters out the good UVB rays. Setting the light on the screen isn't a good idea. The UVB light needs to shine freely into the tank with no screen.

For adults, you can accomplish a fairly good level of humidity just by keeping the substrate moist. I have open top containers that stay in the 70-ish % at turtle level just by adding water to the substrate regularly. The turtles aren't standing in water but the substrate is darkened by the dampness. When the top layer starts to change a lighter color, I pour in more water. Misting is great, recommended, and temporarily boosts humidity, but for humidity control "heavy lifting" use a tea pitcher full of water. Experiment to find the amount of water that gives a good balance between soggy and damp. If you have baby box turtles, the soggier the better. Some people keep them in strictly water based enclosures, no substrate, just an inch or two of water, some hiding places, and some rocks they can climb out on to dry off.That may be a huge part of the problem then... I'll definitely be investing in some guages then. On to my next question, what is the best way to keep the humidity up? They have their own room so would it be best to just buy a humidifier and keep the whole room up, or best for their tanks? My problem with keeping it humid in their tanks is the open screened lids. If the whole room is humid though then I don't have to worry. What do you think?
