huh.... I must have totally misread your original post then, I dunno where it is, but the one from the other day. I thought you were crossing a kush (not OG Kush, but an actual Kush) with the og x gsc cross. Either way, nice mix.
How many generations of clones off your OG you think? And by generations I don't mean rounds, I mean clones of clones. You noticed a change in vigor at all across generations? Do you sexually reproduce them and do pheno selection every once in a while?
