Oh I'll probably take one for the team and do a 1, 2, 3, 5, and 7 gallon grow when these are done. I would say 3 gallon to be optimal for autos.Photos speak for themselves lol
Great comparison to test out, especially with so many people wondering what size pot would be best
Would you make the assumption that a 5 gallon and 7 gallon would show similar steps in size??
