Early 1990s — The Threshold Cannabis Strains
The early 1990s was the most important period in modern cannabis breeding. Within just a few years, Chemdawg (1991), OG Kush (1992), White Widow (1993), Sour Diesel (1993), and Jack Herer (1993) were all released. After 1994, nearly every new strain became a cross of these foundational genetics. 11 entries in this era.
