Setup grow room

2x2 is good for one big plant or two smaller ones. go with the biggest pot you can fit in their without taking up to much room on the height. also 2x2x2 would mean 2 foot high, depth and width that's a perfect square and not normal tent sizing. normally the text go up to 5-7 feet height with equal widths and depths. 2x2x6 or 2x4x6 exct.

A would choose 11L pots instead of 8. More roots more fruits.. thats 6 plant in m2, i grew 9 plant,7L pot, in 80x80cm before.. go with 11L bro.

Depends solely on what youre going for... Sounds like your opting for a SoG with that many Pots the choice is basically more plants ore bigger ones. Personally with that much space i would go for like 8-10 Plants max in bigger pots.
