I use glass because I like the display value and you can make it more close to natural.
As for temp and humidity problems I haven't had any with my set up
and Ozzy has shed twice now and they have been prefect sheds ( as she keeps fingers crossed) and the Vet said he was a good healthy bp so I see know reason to change except on the point that rubbermaids would be a lot easier to maintain.
No offense to anyone who keeps them in rubbermaids because I fully understand the reasons you do and as long as your bp's are happy and healthy thats all that matters but for me keeping my bp in a rubbermaid would be funny cuz I use them for sweaters and christmas trees :)
As my collection grows I am sure at some point I will go for the 'maid.
just wanted to put a plug in that you can have a good bp set up in a glass tank
