Old Red Sour

Old Red Sour is an award-winning sativa-dominant hybrid bred by Oldman Green of Old School Genetics, part of the 'Old School Never Dies' series. It is a 70/30 sativa-to-indica cross of Sour Diesel IBL (the legendary 'Riri cut'), Jamaican Blueberry, and Afghan Red Khyber landrace — three genetically distant lines expertly fused into one powerhouse cultivar. It claimed 1st Prize in the Sativa Category at the 2018 ICMAG Cup Barcelona, earning the highest score across all competing varieties. With THC levels reaching up to 25%, it delivers a fast-acting, cerebral, and psychedelic high with long-lasting euphoria, rounded out by subtle body relaxation from its Afghan lineage. A vigorous grower capable of yielding up to 750g per plant outdoors, with a ~63–65 day indoor flower time.
