I found out, after talking to the Home Depot sales dept, that it depends on what state and what city your local Home Depot is in. They do not all carry the same stuff. I will shoot you a pic of a grow bag.Hmm. Out of all the times I've been to homedepot and lowes I have never seen this grow bags.
People are using the reusable bags you buy at the grocery store and wal mart as smart pots, and its working. These recyclable bags are 3 gallons or more for like a buck or so. look into those if your still gonna do the small container thing. They have handles and are cheap.
