Top Dawg Seeds

Top Dawg Seeds is the New York-based seed program run by JJ-NYC, the breeder credited with stabilizing the modern Chemdawg working lines from the original 1991 parking-lot seeds. The catalogue revolves almost entirely around Chemdawg derivatives — Chemdog '91, Chem D, Stardawg, and Tres Dawg are all in-house releases that anchor much of the modern Chem and Diesel family branches. JJ-NYC has stayed deliberately out of the public eye, releasing seed primarily through trusted forums and a short list of verified retailers rather than running a public storefront. Pack inserts include written breeding notes describing which Chemdawg mother contributed to each cross, which is unusually transparent for an American small-batch program. For preservationist growers Top Dawg Seeds is one of the closest available sources for authentic Chemdawg genetics.
