Jamoka

🧬 The Genetic Archive

The re-release of Jamoka by Greenpoint Seeds represents a milestone in heritage cannabis preservation — reconciling the pungent, landrace-adjacent outliers of the 1990s West Coast scene with the structurally refined “chemical” powerhouses of the modern East Coast era.

This genetic synthesis pairs the legendary San Diego Cat Piss clone with the Kate Upton-descended Star Dawg male, creating a biological archive of the “Concert Stopper” era — when olfactory dominance was the primary metric of quality.

🐱 The Mother: San Diego Cat Piss

The Legend of the Concert Stopper

Unlike the contemporary focus on “dessert” profiles — sweet, doughy, or fruity esters — the San Diego Cat Piss belongs to a class of genetics bred for aggressive, almost offensive sensory presence. This “insider” favorite earned its reputation through an unmistakable ammonia-forward funk so pervasive it could reportedly overpower any other aromatic presence in a crowded environment.

Hence the name: The Concert Stopper.

Origin: Tom and the G13 Snow Bud Genesis

The historical origin traces to a Southern California breeder known simply as Tom. During the early 1990s, Tom was cultivating G13 Snow Bud — prized for its resin density and cold-weather resilience. Upon harvest, a singular lone seed was discovered within the flower.

In cannabis breeding logic, such discoveries often indicate a late-stage stress response triggering self-pollination, effectively creating an S1 (selfed) offspring that isolates recessive traits from the parent plant.

When Tom germinated this solitary seed, the resulting phenotype was a radical departure from expected G13 Snow Bud morphology. While it retained an icy coating of trichomes, the terpene profile shifted to a sharp, acrid, ammonia-drenched aroma reminiscent of concentrated animal urine.

Tom propagated this cut extensively throughout San Diego and into Hawaii, where it gained a cult-like following. The value was so high that later industry figures reportedly paid sums as high as $1,000 just to secure the original cut for genetic research.

⭐ The Father: Star Dawg Kate Upton

The Chemdog Legacy: Deer Creek 1991

The paternal contribution comes from the Star Dawg lineage, developed by JJ NYC of Top Dawg Seeds — a project that redefined the concept of “gas” in the early 2010s. Star Dawg is more than just a strain; it is a genetic nexus connecting the legendary Chemdog lineage to the modern “exotic” market.

The history begins at the Deer Creek Grateful Dead shows on June 6 and 7, 1991. There, 17-year-old Greg “Chemdog” Krzanowski purchased several ounces of high-grade “Dog Bud” from Colorado travelers. Within this stash, Chemdog discovered 13 seeds that would birth the most influential phenotypes in cannabis history:

• ●Chemdog 91
• ●Chemdog Sister
• ●Chemdog D
• ●Chemdog 4 — the maternal anchor of Star Dawg

The Chem 4 is particularly notable as the “Sativa-leaning” anomaly in the typically indica-heavy Chem family — providing a soaring, cerebral rush and chemical-dominant terpene profile that serves as the “engine” for the Star Dawg hybrid.

When JJ NYC crossed the Chemdog 4 with his Tres Dawg male (a backcross of Chemdog D), Star Dawg was born — named after the Mother Love Bone song “Stardog Champion” as tribute to the crystalline “stars” (trichomes) coating its flowers.

Why Kate Upton?

Within the Star Dawg F1 population, JJ NYC identified several distinct phenotypes named after celebrities to describe their physical traits. The Kate Upton phenotype became the definitive “structural” selection.

Greenpoint Seeds selected the Kate Upton male for its role as a “genetic correction” to the unruly growth habits of the Chemdog lineage. Many original Chem-dominant plants suffer from “floppy” stems requiring extensive trellising. The Kate Upton male provides:

• ●Structural integrity — robust, woody frame supporting heavy colas without collapse
• ●Purple potential — recessive allele for anthocyanin production enabling deep lavender and violet coloration
• ●“Statuesque” aesthetics — commercial bag appeal without compromising potency

🔬 The Breeding Logic: Engine Swap

The creation of Jamoka was a strategic endeavor to “engine swap” the San Diego Cat Piss mother — placing its legendary “piss” profile into a high-performance chassis. The breeding logic rests on three pillars:

👃 The Sensory Landscape

The Chemistry of the Stink

The most compelling aspect of Jamoka is the synergy between the mother’s ammonia/thiol profile and the father’s chemical/gas profile. In cannabis science, the “skunk” and “piss” smells are attributed to volatile sulfur compounds (VSCs) or thiols — and the San Diego Cat Piss is exceptionally rich in these compounds.

When crossed with Star Dawg — which contains high levels of Limonene and Caryophyllene — the result is a “sensory assault” combining industrial cleaners with organic decay.

Scientific Note: Research suggests that Limonene, found in high concentrations in the Star Dawg side, increases the permeability of cell membranes. In the context of the Jamoka high, this mechanism may allow potent cannabinoids and unique sulfur compounds of the Cat Piss mother to cross the blood-brain barrier more rapidly — leading to a “transgressive” and immediate cerebral onset.

⚡ Potency & Effects

Jamoka is categorized as a high-potency hybrid, with THC levels frequently testing between 20% and 30%. The effect profile is a “dual-action” experience reflecting its hybrid lineage:

🎯 The Pheno Hunt: Identifying Your Keeper

Growing Jamoka from a pack of regular seeds is described as a “mining” operation. The goal for the serious pheno-hunter is to uncover rare individuals expressing the recessive “Purple Chem” or “Ammonia-Dominant” traits that have been lost to the broader market.

🌱 Cultivation Guide

Jamoka thrives in environments mimicking its Florida and Southern California heritage — high-intensity light and managed humidity. The Star Dawg lineage is known for its “hunger,” particularly for Calcium and Magnesium during the transition to flower.

🏛️ The Greenpoint Legacy

The re-release of Jamoka is part of Greenpoint Seeds’ broader mission to document and distribute the I-95 corridor and Florida Gas genetics that defined the underground era. Founded in 2014, Greenpoint has spent a decade refining its catalog, utilizing elite mothers and the “studly” Star Dawg male to create stable, accessible versions of otherwise unattainable clones.

The I-95 Corridor and the “Gas” Diaspora

The I-95 corridor — the interstate highway connecting major hubs like Boston, New York City, and Richmond — served as the primary distribution vein for the Chemdog and Haze lineages. Strains like the NYC Piff, Sour Diesel, and Chemdog were moved up and down this coast, creating a specific cultural preference for “chemical” and “fuel” profiles over the more “earthy” notes of the West Coast.

Jamoka represents a reconciliation of these two worlds: the “pissy” outlier of San Diego and the “gas” of the I-95 corridor.
