With roots tracing back to the early 1990s, chem 91 skunk va remains a revered cultivar among connoisseurs, breeders, and growers alike.
Origins and History
The origins of Chem 91 are shrouded in mystery and folklore. The most commonly accepted story involves a Grateful Dead concert in 1991, where a group of cannabis enthusiasts, including a grower known as “Chemdog,” acquired some high-quality bud referred to as “Dogbud.” Impressed by its strength and aroma, seeds from this batch were germinated and led to the emergence of the Chem line, including Chem 91.
The “Skunk VA” cut refers to a specific phenotype of Chem 91 preserved and shared by a grower known as Skunk VA. This version is recognized as the most authentic and stable expression of the original Chem 91 genetics. It has been carefully propagated and passed down through decades, gaining a cult following for its unmatched quality and influence on the breeding of other famous strains.
Genetic Lineage
While the exact genetic makeup of Chem 91 Skunk VA is debated, it is widely believed to be a hybrid with dominant sativa characteristics, though it can display balanced effects. The strain is said to descend from a cross involving Thai, Afghani, and possibly Skunk #1 genetics, but due to its underground origins, no definitive lineage has been verified. Nonetheless, its distinct terpene profile and powerful high have made it a foundational parent in modern cannabis breeding.
Aroma and Flavor
