Well i let them get some size in the small cup containers before planting them in 5 gal buckets but there only like 5 weeks into veggie so i wouldn,t think they,d be root bound already,i mainly have potting soil alittle sand and 1/2 vermiculite,so they have a soft base to grow in & alot room lol.Should i take them out of the 5 gal buckets & down size to smaller planters say 3/12 gal size?Or just let them grow,there really healthy and there stalks are like pencil size and i hadn't had no signs of yellowing of leaves yet or wilting at all!
