please show me a pk or an OG kush that yields 600+ grams per sq meter....
Why do people think BB or BB crosses usually suck dick in the potency department? Oh right because they are football cola yielding mids.
again show me a BB cross thats worth anyones time. I grew out BBXNL (freebie from attitude) and it grew fist sized nugs, haven't smoked it yet but it doesn't look promising compared to the cheesequake that got harvested along with it.
I would say environment haas more to do with yield than potency, but above poster is correct.
