i'm trying to make the switch from a glass tank to a plastic tub setup and i'm having issues maintaining the proper ambient temps in the plastic tub. i dont want to have to cut a hole in the lid and use a heatlamp then that would defeat my purpose of switching to the plastic tub which was to maintain ambient humidity levels without having a heatlamp killing my humidity and another thing.. i see all the racks, tub setups and what not and everyone seems to house their BPs with one hide..my question is...does the requirements change when you're dealing with plastic tubs as oppose to glass tanks???
