Gonna be blunt here.
At this point anyone bitching about autos potency, yield or otherwise with basically didn't do their homework or chose a strain that didn't suit them.
There's tons of people that grow them really well @ large yields and great potency.
So when someone bitches bla bla bla my yield sucked, or the potency was shit, what they're basically saying they they're not adaptive enough to grow outside of what they're comfortable growing. aka a lazy or bad grower.
beastly.
