OGK-A doesn't yield for SHIT for me either, and takes forever to go about it. I just wrangled the OGK-SFV to see how that cut does, because the high is unique and lovely. But I just got in the habit of stuffing an OGK in a corner of my flower room and ignoring the shit out of her while I pay more attention to the plants that are being good for mommy hahaha. That's a real 'boutique' strain. If you want yield, there are much better choices.
