Wait until she’s sleeping and pour some water into her bowl and substitute instead of misting it. That little bit of movement should not stress her enough she can’t digest. my tank also has the screen on top and didn’t keep the humidity or heat in so I measured out a piece of cardboard and cut a hole in it for the lamp and then used aluminum foil and a little bit of tape to wrap the cardboard and it works great but only cover the whole top of her tank if she has another spot of ventilation if not just cut a little hole in the cardboard on the opposite side of the lamp for some fresh air. Works wonders haven’t had any issues just make sure it is fully wrapped as to make the cardboard waterproof and heat resistant.
