here's a quote from the thread :
"Not sure exactly what the genetics are on this. i dont know the grower personally just the few brokers who are lucky enough to have access to it. It was Cherry pie female hit with pollen from either a durban or an OG kush. Cherry pie consists of OG kush x GDP x Durban. Im fortunate enough to have the seeds from the cherry pie and the GDPxOG cross however the grower informs that there might be instability in the OG kush that causes self pollination. The GSC has no seeds in it however some samples of cherry pie are known to have seeds. Regardless of the instability concerns, its worth keeping around with a bottle of Reverse because the nug blows away most dispensary inventories. GSC is rarely available wholesale on black market it is always broken down by a select group of dispensarys in the san francisco bay area. and no they dont sell clones of it."
