what up haze man, thanks for the comment, yeah the og kush was from seeds given to me by a coworker, i wish i could get more info about them b/c i was basically just given them by a coworker who knows the grower.
About the clone only- yes "TRUE" OG Kush i believe only comes through clone form, but I suppose this could be a S1 version, although i don't know how anyone could tell for sure. There are just so many watered down or different versions that people claim are a certain true/original strain, that it's hard to know what you've really got.
thanks for checkin in and hope i answered your q.
