Early 1990s — The Threshold Cannabis Strains
The early 1990s was the most important period in modern cannabis breeding — a concentrated burst of genetic innovation that the industry has never repeated. Within just a few years, almost every foundational modern strain was released: Chemdawg (1991) from Grateful Dead tour bagseed, OG Kush (1992) which would become the most influential strain in dispensary history, White Widow (1993) which put Dutch breeding on the world stage, Sour Diesel (1993) defining East Coast diesel terps, and Jack Herer (1993) named after the legendary activist. After 1994, nearly every new strain became a cross of these foundational genetics — the genetic palette was essentially closed. Understanding this era is key to understanding modern cannabis. 15 entries in this era.

Bubble Gum
Bubblegum, Bubble GumA multiple Cannabis Cup winner and one of the first 'candy' strains. Bubble Gum was a breakthrough: it proved that cannabis could taste sweet and fruity — like pink bubble gum — while still delivering potent effects. It opened the door for the dessert strain explosion.
