Has anyone ever used these? Zoo Med Hydro Balls I am thinking about getting some and putting a bowl of them in the corner of my corn snake's cage underneath the light to raise the humidity...dunno if it's a good idea or not. The other idea that I got here (courtesy of Merlin) was to use a second water dish. These are supposedly meant to be soaked and then keep humidity levels up? Has anyone used them before? I want to make sure they are OK for him to be burrowing in if he decided to... Thanks.
