Highest Yielder

Does anyone have experience with very high yielding strain and what are some very low yielders

my sour diesel are not that high of a yielding plant.

The old 1990's Big Bud is a HUGE yielder. And...it's crap. I grow mostly Bubba, a medium yielder, but fantastic quality. We also grow a Lavander x Afgan x Purple Kush cross that yields around 50% more than the Bubba and is also terrific quality. Go for quality and develope your growing skills to increase yields.
