I've grown in FF soil and also in coco. I'm thinking about moving to a RDWC setup... I already ordered a 1/4 water chilling, and 2" uniseals. Now I'm just trying to get the rest of my supplies. To get to my question, I'm debating on whether to go with eight 8 gallon square buckets vs eight standard 5 gallon round buckets in a 4x8 tent. Any pros, cons, difference in using one over the other other than cost? I'll be vegging for appox a month if that makes a difference..
