Wow...so are you telling me i dont need pots the size of 2 liter bottles like i am using in my first soil grow?

I am only looking to get about an oz per plant. Will 3" pots work ok if im only looking to do a SOG?

I will buy the 32 pot set up if ya'll think i could grow a SOG from start to finish in it.

What do you consider "large"? How big of a plant (in harvested grams or oz) is about as big as you can go in a 3" pot like the ones i found?
