I am current using aspen and moss to try to keep the humidity up for my 4month old ball python. I have a 40gallon glass tank with a screen top. I covered about 60% of the screen with a damp towel and mist it twice a day. The humidity currently is 55% and drops to 35-40% after a few hours and at night it seems to be fine between 50-60%, but with misting. Does anyone recommend Zoo Med Eco Earth Compressed Coconut Fiber Expandable Substrate? The only reason why i am considering the change because the humidity drops while i am at work for 8hours, and do not want it to harm my boy.
