I’ve ran sog in 1 gallon pots flipping a couple weeks from rooted clone. I would see one or two get root bound from time to time. I would assume would be slightly better with fabric pot that self prunes.
I would look for something a little larger, hopefully 1 gallon plus. If you’re growing from seed, make sure you start in small cup and kind of let them stall out before you transplant. The timing from pot to pot can help you out a bunch. I’ve never tried it on a flood though.
