I did 10 plants in a 4x4 in 2 gal pots.
Somethings I didn't consider
Smaller pots you're going to get root bound much quicker, meaning You have to water like 1-2 times per day in some cases.
Watering is a pain you can only give small amounts of water at a time to avoid flooding and spiking your humidity.
Reaching the plants to water them, you will end up bumping them and getting covered in resin.
I think sog grows are done best in a flood and drain table. Which I wouldn't use soil for.
Also don't forget stakes like I did. Support becomes a big issue.
Good luck!
