My Saharan sand boa's bin is around 60% humidity, when it should be lower than 40%. My room alone is 50%. I have a screen lid, holes in the tub, everything, but the ambient humidity in my room is just too high. I have a computer fan I'm not using.
Would it work if I set the fan on top of the bin, pointing down through the screen mesh? How much would it lower humidity (estimation, obviously)? Or would I be better off using some other method?
