Initially I was going to go with a hatchling rack and then near November/December try and get a 12-15qt rack for my "grow up rack" until they are big enough to fit into 28qt tubs. However, when I was inquiring about a rack, I was advised to think about V-18 racks. I didn't see why that would be better since it's just longer than a shoebox. I figured a shoebox tub could easily hold a snake up to 200-300g if not a little larger. By that time, I would have a 12 or 15 qt rack to put them in.
