818 Headband (also known as Sour OG) is a balanced hybrid bred by The Cali Connection, created by crossing Original Sour Diesel × SFV OG Kush IBL. This classic cultivar typically tests between 20–28% THC with less than 1% CBD. It produces dense, resin-covered buds with bright green coloration, occasional purple hues, and vibrant orange pistils. Its terpene profile is commonly dominated by myrcene, limonene, and caryophyllene, delivering a pungent aroma and flavor of sour diesel, lemon, pine, earth, and classic OG fuel. The effects begin with an uplifting, focused cerebral rush before settling into a deeply relaxing body high that eases tension without immediately causing couch-lock. A multiple award-winning strain, 818 Headband is celebrated for combining the unmistakable fuel-forward character of Sour Diesel with the heavy resin production, potency, and relaxing finish of SFV OG Kush, making it a favorite among both flower and concentrate enthusiasts.
