I'm very new to the ball python community, getting my first snakes a few days ago. They seem to be settling in fairly well, but I just had a few questions involving substrate. I have an RBI rack and I am currently using paper towels, but have had trouble with any amount of split water causing a large wet spot among a majority of tub floor. I have been continually changing it when this event occurs because 1) I don't want them to be sitting on a wet or damp surface (is this a legitimate concern?) and 2) the damp paper towel causes condensation on the front of the tub and a humidity of around 80% (normally somewhere between 60-70%). But wish I didn't have too because I am trying to let the snakes calm down and settle in. I guess my questions are as follows: is a wet substrate bad for the snake? is condensation on the front of the tub a good or bad thing (assuming 80% humidity is good for snakes in shed)? and is this problem just an indication that I should switch substrates?
