Hey everyone, Im having a hard time with building a rack. Mostly because i am so indecisive, i would like to A. save money, B. keep weight down, and C. have some type of uniformity because i will most likely be building more when hatch-lings come and my females get BIG! My problem is i dont want to use melamine, id like to avoid spending that much, and its heavy. I cant track down pvc sheets ANYwhere and again it would still probably be a little pricey. So im looking for alternatives and i dont see why plywood wouldnt be feasible. I need it to hold 28 qt sterilite tubs since they dont make 32 anymore ( i think the dimensions are the same though) and i was thinking of just using some type of sealant on the underside of the shelves to keep the humidity from warping the wood. I was wondering if anybody had used plywood or had any other ideas. Maybe a suggestion on a sealant that is no toxic, i dont want my snakes getting sick. Any advice would be greatly appreciated im having a hard time. Thanks
