Why it spread

It was scarce, loud and expensive at a time when most growers favored indicas, which grow faster and yield more.^2,3 Leafly credits Sour Diesel with bringing sativas back and with putting an East Coast strain in the spotlight for the first time.³ In New York it sold for about $50 for two grams and quickly won over the city’s connoisseurs and hip-hop stars, according to High Times.¹

The early scene had a home base: Barney’s Farm says much of it revolved around Wetlands Preserve, a Tribeca nightclub open from 1989 to 2001, and Top Dawg Seeds told High Times it met AJ there.^2,7 Cuts later spread from Staten Island and Manhattan to Long Island, Albany and the West Coast, picking up names like East Coast Sour Diesel along the way.²

The disputed parts of the story

• Who made it: Weedmaps News and SeedFinder credit AJ as the breeder, High Times says he named it, and Leafly calls the original breeder unknown.^1,4,6,16
• What “Diesel” first meant: a new name for the Chem cut itself, according to Top Dawg Seeds and Barney’s Farm, or the name AJ gave the accidental cross, according to High Times.^1,2,7
• The second parent: Super Skunk, an unknown hermaphrodite or lines with Northern Lights in them (see genetics).^1,17,18
• When: Leafly says it became popular in the early 1990s; High Times dates the name to late 1994; Barney’s Farm and SeedFinder say around 1996.^1,2,6,17
• Where: most accounts say New York; DNA Genetics notes that some stories point to West Coast growers, while SeedFinder calls the California attribution a mistake.^6,19
