I have 9, 10 gallon totes. I have lids for them with 1, 2 or 6 holes in them for baskets. The 6 hole lid is only for plants in their early stages once they start to intermingle I move the baskets into either a 1 or 2 hole lid. Doing it this way cuts back on work that needs to be done early on. Two plants in a 10 gallon tote would be the max I would try to grow through to flower. The picture I included shows 3, 10 gallon totes each with 2 plants in them. I also have 18 gallon totes and grew 4 plants from clones in them.
