Top Dawg Seeds: Legendary Chem & Sour Diesel Genetics from JJ-NYC

If you’ve spent any time in serious cannabis circles, you already know the name. Top Dawg Seeds is the creation of JJ-NYC — a breeder whose work spans over two decades, whose genetics have shaped the American cannabis landscape from New York City’s underground market to dispensary shelves coast to coast. Creator of Stardawg, Tres Dawg, Nigerian Haze, and dozens more defining strains, JJ-NYC is not just a breeder — he’s an architect of modern American cannabis genetics. Seeds Here Now is proud to carry authentic Top Dawg Seeds, including current releases available now.

The Story Behind Top Dawg Seeds: From NYC Underground to Hall of Fame

JJ-NYC’s story begins where so much of American cannabis history does — in New York City. He first encountered cannabis in 1992, navigating the underground flower scene that defined the NYC market. By 1999, he had started growing for himself, initially experimenting with Amsterdam genetics including a Jack Herer cut from a friend. But it was when JJ gained access to the original Chemdog clone and Sour Diesel — trading with legendary cultivators AJ and Chem Dog himself — that the Top Dawg genetic library truly began to take shape.

Operating mostly out of a farmhouse in the Catskills in New York’s Hudson River Valley, JJ honed his growing and breeding skills through the early 2000s while staying connected to the NYC underground market. His participation in landmark cannabis forums — Overgrow, IC Mag, and THC Farmer — gave him access to a global network of elite breeders and genetics, while his on-the-ground NYC hustle ensured he understood what serious consumers actually wanted: the dankest, most complex, most potent flower possible.

JJ started creating seeds in earnest around 2006–2007. The first releases circulated as clones among trusted cultivator friends before moving online. Within a few years, his genetics had taken on a life of their own — seeded out to Humboldt County and beyond, building a following among the most discerning growers in the country. The recognition was formalized in 2011, when JJ won the San Francisco High Times Cannabis Cup and was inducted into the prestigious High Times Breeder Hall of Fame — one of the highest honors in the cannabis industry. Around 2015, JJ relocated to Colorado, where Top Dawg Seeds continues to evolve.

JJ-NYC’s Breeding Philosophy: Preserve the Legends, Build the Future

What drives Top Dawg Seeds is a mission that JJ-NYC has never wavered on: preserve every elite strain before it disappears. In the underground market of the 1990s and 2000s, he watched irreplaceable genetics vanish when suppliers changed or got out of the game. His response was to secure clones before that could happen — and then put those genetics to work through disciplined backcrossing and selective breeding. The Top Dawg approach centers on:

Authentic lineage preservation: JJ works directly with original source material — Chem D obtained from Chem Dog himself, Sour Diesel traded directly with AJ, Nigerian Silk sourced in NYC in the early 2000s. There are no secondhand genetics in the Top Dawg catalog.
Backcross stabilization: Flagship strains like Tres Dawg were backcrossed twice before release to deliver the consistency and stability that serious growers expect. If a strain carries the Top Dawg name, it has been rigorously worked.
Male selection discipline: JJ is meticulous about his males — selecting for late flowering, strong stem-rub aromatics, and visible resin on leaves and stems under a loupe. The male is half the genetics, and Top Dawg treats it that way.
Terpene-first flavor profiles: From the diesel-fuel punch of Chem-based crosses to the sativa haze brightness of Nigerian Haze and Disco Haze, JJ’s catalog prioritizes complex, loud aromatics over commercial yield metrics.
Regular seeds for breeders: Almost the entire Top Dawg catalog consists of regular cannabis seeds — a deliberate choice that supports the breeding and pheno-hunting community, the same community JJ came up through. These are genetics meant to be worked, not just grown out.

The result is a catalog spanning 170+ strains that reads like a comprehensive archive of the finest American cannabis genetics — Chem, Sour Diesel, OG, Haze, Skunk, Thai, and beyond. Every release is a chapter in an ongoing story of preservation and creation.

Top Top Dawg Seeds Strains Available at Seeds Here Now

Here are some of the most sought-after Top Dawg Seeds strains in our current catalog — each one a direct product of JJ-NYC’s decades of genetic work:

Stardawg (The Flagship)
Genetics: Chem 4 × Tres Dawg | Seed Type: Regular | Flowering Time: ~67 days | Mostly Indica
If there is one strain that defines the Top Dawg legacy, it’s Stardawg. Born from the union of Chem 4 and Tres Dawg (itself an Afghan #1 × Chem D backcross), Stardawg encapsulates everything JJ-NYC set out to achieve: a dense, frosty, gas-forward indica-dominant hybrid that delivers knockout potency, classic Chem aromatics, and phenotypic consistency that breeders prize. The Guava cut of Stardawg — known worldwide — became a pillar of modern cannabis genetics and has spawned over 180 documented hybrids across the industry. Stardawg is the reason JJ earned his Hall of Fame induction, and the reason cultivators keep coming back to Top Dawg Seeds generation after generation.

Disco Haze (Regular)
Genetics: Fort Collins Cough × Chem D × Original Haze | Seed Type: Regular | Flowering Time: 70–84 days | THC: 18–22% | Sativa-dominant (80/20)
Disco Haze is JJ-NYC’s haze masterwork — a sativa-dominant behemoth that marries Fort Collins Cough with a Chem D × Original Haze cross for a strain that’s as cerebral as it is aromatic. Expect uplifting, creative, and social effects backed by a citrus-pine-spice nose dominated by Humulene, Caryophyllene, and Linalool. At 70–84 days flowering, this is a long-season project that rewards patient growers with some of the most complex terpene profiles in the catalog. Ideal for haze enthusiasts and anyone hunting a connoisseur sativa experience.

Chem Wrecker 2 is a full-Chem assault — a double-Chem D cross that delivers the purest expression of JJ’s foundational genetic obsession. Zesty diesel-pine aromas, balanced indica-sativa effects, and a reliable 63–70 day flower window make this a grower’s strain through and through. This is the pick for collectors who want an uncut, unapologetic Chemdog experience backed by two decades of JJ-NYC’s selection work. Available as regular seeds for breeders and pheno-hunters.

Banana Fizz (Regular)
Genetics: Banana OG × Bubblegum Chem | Seed Type: Regular | Flowering Time: 63–70 days | THC: 18–22%
A more recent side of Top Dawg’s catalog, Banana Fizz shows JJ’s range beyond the core Chem/Sour lineage. Crossing Banana OG with Bubblegum Chem produces a tropical, indica-leaning hybrid bursting with banana, citrus, and sweet aromas driven by Myrcene, Humulene, and Ocimene. Effects are energized, creative, and relaxed — a versatile day-to-evening smoke with broad commercial appeal. At 63–70 days, it’s one of the more accessible entries in the catalog for newer growers.

Citron City (Regular)
Genetics: Tangerian Haze × ONYCD | Seed Type: Regular | Flowering Time: 63–70 days
Citron City is JJ-NYC’s haze-meets-NYC-underground hybrid — combining Tangerian Haze with his own ONYCD (One New York City Diesel), a strain JJ created specifically to reclaim the name of NYC Diesel from what he considered an inferior commercial version. The result is a zesty, citrus-drenched sativa hybrid packed with uplifting, creative energy. This is a true NYC strain: fast-talking, sharp, and impossible to ignore.

Sour P 21 (Regular)
Genetics: Jane Doe Kush × Sour Diesel F2 | Seed Type: Regular | Flowering Time: 63–70 days | THC: 18–22%
Sour P 21 anchors the Sour Diesel branch of JJ’s catalog — crossing Jane Doe Kush with a second-generation Sour Diesel cross for a strain with citrusy, fuel-forward aromas and a creative-to-relaxed effect profile. At 63–70 days, it’s efficient for a Sour Diesel lineage strain and delivers the potency and flavor that has made JJ’s Sour-based genetics some of the most sought-after in the US market.

Awards & Hall of Fame Recognition

Top Dawg Seeds’ reputation isn’t built on hype — it’s built on verified competitive results and decades of community respect. JJ-NYC won the 2011 San Francisco High Times Cannabis Cup, one of the most prestigious cannabis competitions in the world, placing him among the elite breeders of his generation. That same year, he was inducted into the High Times Breeder Hall of Fame — a recognition reserved for breeders whose work has had demonstrable, lasting impact on the culture and genetics of cannabis.

The legacy is further evidenced by Stardawg’s influence: over 180 documented hybrids have been created from Top Dawg genetics by breeders worldwide, appearing across seed banks on every continent. When a strain becomes a foundation that other elite breeders build upon, that’s the truest measure of genetic greatness.

Growing Top Dawg Seeds: What to Expect

The Top Dawg catalog skews toward experienced and enthusiast growers — these are connoisseur genetics that reward proper technique. Here’s what to know before you pop a pack:

Seed type — all regular: Nearly all Top Dawg Seeds are regular cannabis seeds, meaning you’ll get both male and female plants. Experienced breeders will appreciate the opportunity to hunt phenos and work the genetics. New growers should be prepared to sex plants at flowering onset.
Flowering times vary by line: Chem and OG-based strains typically finish in 63–70 days. Haze-dominant strains like Disco Haze run longer — 70–84 days — and deliver the terpene complexity that extra time affords.
Chem strains: watch for hermies: Chemdog-derived genetics have a reputation for hermaphrodite tendencies under stress. Keep your environment dialed — stable temperature, consistent photoperiod, and minimal late-flower disturbances. JJ’s Tres Dawg line is notably stable for a Chem cross, but care is still rewarded.
Haze phenos: patience pays off: The sativa-leaning and haze strains in the Top Dawg catalog are not for impatient growers. Stretchy, long-flowering, and picky about humidity — but the payoff in terpene complexity is unmatched.
Training and structure: Most Chem-based Top Dawg strains grow short to medium height with dense, resinous bud structure. Top and LST work well for maximizing light penetration. Haze-dominant strains will stretch — plan canopy accordingly.
Pheno hunting: Top Dawg genetics are known for producing multiple distinct phenotypes within a pack. Legendary cuts like the Guava Stardawg were found this way. Run larger pack sizes if you’re hunting a specific expression.
