If I change my substrate that I am currently using from coco fiber to newspaper how difficult will it be for me to keep the humidity stable? I am housing my snake in a 20 gallon long tank. The humidity is currently at 55%. What can I do to make sure my humidity stays stable when switiching to newspaper? I have the lid of the tank inuslated with aluminum foil and duct tape with some space for venitlation of course. I would really appreciate any feedback that any of you may have. Thanks.
