So when I go to Home Depot, what material do I ask for (I'm guessing that is melamine) and what measurements do I ask for when I ask for the cuts? I was planning on purchasing a hatchling rack but if I can make one with 2x as many tubs for 1/2 the price that would be awesome. Actually I might cut these measurements in half and make one with only 12 tubs....or something like that. Thanks for answering my questions.
