im not sure buddy this is my first run with a 3 gallon pot,the old school guys say the bigger the pot the bigger the yeild.
that is true, to a point.
its actually, longer the veg, better the yield, but to veg longer and not get root locked, you need bigger pots.
a plants yield is based largly on its root mass.
i wouldnt go anything under a 3 gal pot. but when i replace everything with root pots, i will go with 5 or 7's
going a 5 or 7 on a 12/12 from seed/clone wont improve yield. if its not root locked, then you dont need bigger pots.
I try my best to do 1 gal per month of growth. Running almost all 60 day strains. 1 Month in veg + 2 month flower = 3 gal pots.
Some strains run longer in veg, like the pineapple and my timewarp, so they need bigger pots.
