What is the Old Chemdog strain?
Old Chemdog is a hybrid cannabis strain with up to 25.0% THC, known for its euphoric effects and citrus and diesel flavor profile.
Old Chemdog is a legendary cannabis strain with a storied history dating back to the early 1990s. The strain's origin story is well-documented in cannabis lore: it began when a grower known as 'Chemdog' purchased an ounce of particularly potent cannabis at a Grateful Dead concert in 1991. From those seeds emerged what would become one of the most influential strains in modern cannabis breeding. The original Chemdog genetics have been preserved and propagated by dedicated growers, with 'Old Chemdog' specifically referring to the original phenotype that maintains the classic characteristics of the early 1990s genetics.
The strain exhibits a distinctive appearance with dense, elongated buds that are typically lime green with vibrant orange pistils. The flowers are heavily coated in trichomes, giving them a frosty, crystalline appearance. Old Chemdog is renowned for its pungent aroma that combines diesel fuel, skunk, and earthy undertones with subtle citrus notes. The flavor profile is similarly complex, delivering a sharp, fuel-like taste on inhalation that transitions to earthy, piney notes on exhalation.
Old Chemdog has achieved legendary status not only for its potent effects but also for its genetic contributions to the cannabis world. It serves as a parent strain to numerous popular hybrids including Sour Diesel, OG Kush, and many other notable varieties. The strain's genetics have been carefully preserved by a small group of dedicated breeders who maintain the original phenotype, making authentic Old Chemdog relatively rare compared to its many descendants and variations.
