JJ-NYC and Top Dawg Seeds

Top Dawg Seeds is JJ-NYC’s breeding project, rooted in the New York and East Coast genetics scene. At Old School Genetics, we present each release with breeder attribution and its stated parentage, generation or selection where documented. This keeps the original cuts, later seed lines and distinct outcrosses clear as readers explore the catalogue. JJ has described breeding Tres Dawg from Chem D and Afghani #1 through two backcrosses. He identifies Star Dawg as Chem 4 crossed with Tres Dawg. His catalogue also extends into Nigerian Haze and the Piff and NYC Haze world, alongside Sour Diesel projects and other heritage lines.

The original Chemdog cuts and the work of other keepers retain their own attribution. OSG presents selected Top Dawg releases; it does not claim authorship of them.

Family 01 / Chem & Dawg

Chem & Dawg Genetics by Top Dawg Seeds

JJ-NYC’s Chem & Dawg work builds on the original Chemdog cuts while distinguishing those cuts from his later seed lines. In JJ’s account, Tres Dawg began with Chem D and Afghani #1 and was backcrossed twice; Star Dawg joins Chem 4 with Tres Dawg. Those relationships explain a core route, not the full pedigree of every later release. Old School Genetics groups eleven related Top Dawg Seeds releases here, including Star Dawg, Dirty Chem, Guava Star and Nigerian Chem. Each product page records its stated cross and generation or selection where available. Explore Chem & Dawg genetics

Family 02 / Sour Diesel

Sour Diesel Genetics by Top Dawg Seeds

Top Dawg’s Sour Diesel projects form a distinct path through its seed catalogue. The nine Old School Genetics releases in this route include an in-line Sour Diesel offering and outcrosses whose product pages name Chem 91, GMO, Triangle Kush, Pure Kush, LA Headband, Northern Lights, Albert Walker and Super Skunk as other parents. Labels such as F4, F5, F6 and BX3 describe specific material or releases. We keep those designations attached to the relevant product rather than applying one generation to the entire Sour Diesel family. Explore Sour Diesel genetics

Family 03 / Piff, NYC Haze & Heritage

Piff, NYC Haze & Heritage Genetics by Top Dawg Seeds

JJ-NYC’s Haze work reaches from NYC Piff and Black Haze to Nigerian Haze and projects involving A5, Thai, Burmese and Vietnamese material. Old School Genetics brings nine current releases together as a way to navigate this wider part of the Top Dawg Seeds catalogue. This is an editorial collection, not a claim that every variety shares one Piff parent or one family tree. Individual product pages retain the stated lineage, named selections and generation for each release where documented. Explore Piff, NYC Haze & Heritage

Questions

Top Dawg Seeds FAQ

Who is JJ-NYC?JJ-NYC is the breeder behind Top Dawg Seeds. His documented work includes projects using Chem D, Chem 4 and Sour Diesel, the development of Tres Dawg and Star Dawg, and releases involving Piff, NYC Haze and other Haze and heritage material.
What is the relationship between Tres Dawg and Star Dawg?JJ-NYC describes Tres Dawg as his Chem D and Afghani #1 backcross project. Star Dawg combines Chem 4 with Tres Dawg. Specific Star Dawg generations and named selections must be documented individually; the original parentage alone does not describe every later seed release.
Are all Top Dawg Haze releases Piff?No. Piff and NYC Haze are one route through a broader Haze catalogue. Nigerian Haze, A5, Thai, Burmese and Vietnamese releases retain their own stated pedigrees. A shared Haze name does not establish a Piff parent.
Does Top Dawg only work with Chem genetics?No. Chem & Dawg genetics are central to Top Dawg Seeds, but JJ-NYC’s catalogue also includes Sour Diesel, Piff, NYC Haze and distinct Haze and heritage projects.
Which Top Dawg releases are currently available?Stock changes as packs sell out or return. The live Old School Genetics catalogue and individual product pages provide current availability, pricing and pack details.
