120x60x180 (2x4x6) number of plants

O that's the same sized tent I have. 2 feet by 4 feet by 6ish feet Secret Jarden darkstreet 120w is my model. I like sog, I would do max 6-8 plants in 3Gal/12L pots each. As they will grow out with some LST and take up the rest of the footprint of the tent. But 12 could also work. 3X4 grid just really really tight. If you was to drop the pot size down again you could do more, but I don't think it should be smaller then 3gal. especially for autos. But I think scrog is more popular. It also would have more of a controlled product. Less pheno types and such if your growing from seeds vs clones. I also think you use less feed overall in a few bigger plants vs a bunch of smaller ones. What ever you chose you'll do well.
