Hello. I am just looking for some advice on whether or not I should get a plastic cage. I have a glass tank right now for my ball python and the humidity does not seem to hold much over 50%. Im using aspen and was wondering if the plastic would work better and where I could go to find a good one. Also was wondering if under tank heater is good to use, which is what I've been using cause if i have a light on over the tank the air dries up. The last couple sheds have been bad so I am trying to correct this so my snake can be more comfortable. Thanks! This is the first snake I have ever owned, everything I have done has been from research but all the suggestions i have find about humidity don't seem to work or Im doing something wrong.
