Im planning on building a rack for my adult ball pythons. My question is if im going to use back heat do I need to have a solid floor for the tubs to sit on. Im planning on using 3/4" MDF and leaving the lids on the five tubs at all times. I want to try and keep the weight and material costs down. I was planning on running 3" runners down the sides to support the tubs. Any help would be greatly appreciated.
