From RQS "Royal Queen Seeds breeders worked hard to develop our own version of the legendary OG Kush. Using a mix of Chemdawg, Lemon Thai, and Pakistani Kush, they created a well-rounded strain with high THC levels and bucket-loads of fruity terpenes. Overall, she features a stoning genetic profile of 75% indica genetics and 25% sativa.
Its true genetics are unknown. Some say OG Kush is a mix of ChemDawg with a Lemon Thai and Pakistani Kush. Others say that it’s just a special cutting of ChemDawg from the early 90s. Even the meaning of the name OG has been debated; with some saying it means Original Gangster. However, now, because of its origins, most people agree it means Ocean Grown."
The seeds might be fantastic, I don't want to sew doubt, but its not the og kush that og kush enthusiasts talk about.
Large seedbanks do this all the time with strains that are popular enough that the layman knows them. They breed their own stock and call it OG kush or white widow or blueberry when it's really just a run of the mill polyhybrid. Again, this weed can be really good, but its shady marketing imo.
