Ok, so I am getting my first bp soon! Im going to be ordering a ghost ball python, and he is going to be my first snake. I am going out to buy all my supplies today, and my biggest fear is humidity!! I am going to be usibg a glass tank with the locking screen lid...which obviously wont hold in the humidity...soo my question to all of you is, how do you keep your humidity up?? Should i cover part of the screen, and if soo with what?? Or is a certain type of substrate better for humidity? I was going to go with aspen, but that doesnt seem like it would hold in alot of water..And last question(lol can you can telll im neeew to this?) I was going to get a 40 gallon tank for him and start him in that..but im noticing alot of you guys say bigger isnt always better for snalkes, so if i put in a buuunch of hides, plants etc, would be okk?
