Yep, it's all relative to the amount of healthy root mass. Like I've said over and over again, folks tend to focus on bud production rather than root and foliage production.
I knew a guy at OG who grew out some Vietnamese Dalat in 10 gallon pots and got 3 lbs. of bud from each one. He used to grow huge plants indoors, took his hobby very seriously.
Again, it's all in the balance. I just don't see any value in using small pots (and I don't see any value in using oversized pots). Is it because one can't afford the cost of potting soil?
