Easy Grow
“Thirteen seeds from a gravel parking lot at a Grateful Dead show in Indiana. That’s where the entire Chemdog bloodline started. The Corey Haim cut of Stardawg is the black sheep of that family — volatile, intense, and too much for most to handle. We inbred it into an auto because the world needed access to that industrial gas profile without needing a warehouse to grow it.”

Breeding Logic
Domesticating the Corey Haim
How an inbreeding program turned the I-95 corridor’s most volatile Chem selection into a 100-day autoflower.
Start With the Hardest Cut
The Corey Haim cut of Stardawg is the black sheep of the family for a reason — it’s volatile, it’s intense, and it’s the most potent selection from JJ NYC’s original Stardawg seeds. Hairspray, garlic, raw industrial chemical funk. The F1 cross used this specific cut because there’s no point auto-breeding a watered-down version of something. You start with the heaviest hitter and let the inbreeding refine it.
Lock the Auto Trigger
The day-neutral flowering trait from Low Ryder is recessive. The F1 cross produced all photoperiod carriers. Inbreeding those carriers forward gave autoflowering individuals in the F2 — roughly 25% of the population. From there, every subsequent generation was selected from the auto-flowering pool, refining the line while ensuring the trigger was locked and reliable.
Inbreed, Don’t Backcross
This line wasn’t backcrossed to the Corey Haim mother — it was inbred forward from the F1. That’s a different strategy. Backcrossing would have pulled the population closer to the original clone. Inbreeding lets the population find its own equilibrium, retaining the Corey Haim influence while allowing the auto traits to integrate naturally across generations.
Select for the Gas
Every generation, the selection criteria stayed the same: keep the ones that smell like the Corey Haim. Hairspray. Garlic. That ammonia-pine chemical burn that makes your eyes water when you open the jar. If the terpene profile drifted toward the ruderalis parent — flat, grassy, unremarkable — those plants didn’t make the cut. The gas is the identity.
Mother Line
Stardawg — Corey Haim Cut
The black sheep of the Top Dawg family — volatile, narcotic, and offensively loud. The most potent Stardawg selection and the starting point for this auto line.
Stardawg is Chem 4 × Tres Dawg, created by JJ NYC of Top Dawg Seeds in 2011. The naming was an intentional homage to “Stardog Champion” by Mother Love Bone, and the “dawg” suffix — rather than “dog” — was JJ’s way of distinguishing his seed work from the original 1991 Chemdog clones. That dog vs. dawg distinction is inside baseball for breeders, but it signals a specific lineage of East Coast gasoline genetics and a deep respect for the original material.
The Chem 4 mother in Stardawg came from those original thirteen seeds found in a bag of “Dog Bud” at the Deer Creek Music Center during a Grateful Dead run in June 1991. A young grower from Massachusetts named Greg Krzanowski — known to the culture as Chemdog — bought an ounce from two Colorado travelers, P-Bud and Joe Brand. The seeds from that bag produced the most influential cultivars in modern cannabis history: Chem 91, Chem D, Chem Sister, and Chem 4. The Chem 4 wasn’t popped until a reunion of the original crew years later, earning it the nickname “the Reunion Matriarch.” Its organoleptic signature shifted away from the roadkill skunk and burnt rubber of the earlier Chem selections toward something sharper — industrial cleaner, ammonia, and lemon-pine. That chemical profile is the soaring, cerebral engine inside Stardawg.
The Tres Dawg father was JJ NYC’s own stabilization work — Chem D × Afghani #1, backcrossed twice to lock the Chem-heavy traits while gaining structural density and faster flowering from the Afghan side. Tres Dawg introduced deep, roasted notes of coffee and damp earth that grounded the high-frequency chemical noise of the Chem parent. It was the “stabilizing anchor” for the Stardawg line.
The Corey Haim Cut
The Black Sheep
Among the various Stardawg phenotypes — the tropical Guava, the structural Kate Upton male, the Illuminati private selection — the Corey Haim cut stands apart. Popularized by the breeder AJ of ECSD fame, it was named for reasons AJ shares only in person, though the name inherently suggests something “too much for most to handle.” The terpene profile is dominated by hairspray, aerosol chemicals, and raw garlic. It’s the most potent Stardawg selection — a narcotic, sedative heavy-hitter that starts with a cerebral mood boost and transitions into body-flattening couch-lock. This is the headstash cut. This is what anchored the F1 cross for Stardawg Auto.
June 1991
Deer Creek Music Center, Noblesville, Indiana. Grateful Dead two-night run. Chemdog buys an ounce of “Dog Bud” from P-Bud and Joe Brand. Thirteen seeds discovered in the bag. The Chemdog bloodline begins.
1991–2000s
Chem 91, Chem D, and Chem Sister popped from the original seeds. These clones define the I-95 corridor gas market and become the maternal foundation for modern hybrid breeding.
Later Reunion
Chem 4 popped at a reunion of the original crew. The “Reunion Matriarch” — sharper than the earlier selections, leaning into ammonia, industrial cleaner, and lemon-pine. The future mother of Stardawg.
2011
JJ NYC of Top Dawg Seeds crosses Chem 4 × Tres Dawg. Stardawg is born. Multiple phenotypes identified, including the Corey Haim cut — the most volatile and potent selection.
Greenpoint F1
Corey Haim cut crossed to Low Ryder. All F1 offspring are photoperiod carriers of the recessive auto gene. The starting point for the inbreeding program.
Inbreeding Program
F1 carriers inbred forward. Autoflowering individuals selected in F2 and carried through subsequent generations. Selection pressure: retain the Corey Haim gas profile, lock the auto trigger, stabilize the population. No backcrossing to the original clone.
Inside Baseball — Dog vs. Dawg
JJ NYC used the “dawg” suffix to distinguish his seed work from the original 1991 Chemdog clones. If it says “dog,” it refers to the Greg Krzanowski originals — Chem Dog, Chem 91, Chem D. If it says “dawg,” it’s from JJ’s breeding program — Stardawg, Tres Dawg, and the broader Top Dawg catalog. Knowing the difference tells the room you know where the gas actually comes from.
Context
Stardawg Phenotype Map
Where the Corey Haim cut sits relative to the other known Stardawg selections.
Known Stardawg Phenotypes
| Corey Haim | Hairspray, garlic, chemicals — narcotic, body-flattening. The one we used. |
| Guava | Fermented fruit, sweetness — electric, uplifting, social. JJ NYC selection. |
| Kate Upton | Chemical pine, lemon gas — stocky frame, purple hues. Structural donor. |
| Illuminati | Pine-Sol, earthy diesel — compact, cerebral, introspective. Private selection. |
Why Corey Haim
The Corey Haim was chosen for the auto project because it’s the heaviest hitter in the Stardawg family. If you’re going to go through the effort of inbreeding a photoperiod elite into auto format, you start with the most extreme expression of the line. The gas profile, the potency ceiling, the narcotic effect — that’s the genetic material worth preserving. You can’t add intensity later. You can only try not to lose it.
Father Line
Low Ryder — Ruderalis Auto Chassis
The Joint Doctor’s three-decade project that made day-neutral cannabis possible — the genetic switch that turns a photoperiod elite into an autoflower.
Cannabis ruderalis spent decades being dismissed as ditch weed — a wild species from Eastern Europe and Russia with negligible THC and rope-like structure. What it had was the one trait nobody else could offer: day-neutral flowering. Ruderalis flowers based on biological age, not photoperiod. No light cycle manipulation required. For a species that evolved in northern latitudes with brutally short summers, that was survival. For breeders, it was a switch they could insert into any elite line.
The Joint Doctor spent nearly thirty years turning that switch into a usable breeding tool. The original Low Ryder was a three-way cross: Northern Lights #2 × Mexican Ruddy × William’s Wonder. The William’s Wonder was the key ingredient — a refined Afghani line from Sam the Skunkman and Sacred Seeds that brought commercial-level resin production and potency to the ruderalis chassis. The result was the world’s first reliable autoflower, completing its full lifecycle in as little as 60 days.
In the context of the Stardawg Auto project, the Low Ryder exists for one reason: the auto trigger. Everything else the Low Ryder contributes — stature, terpenes, potency — is something the inbreeding program selected against. Keep the switch, lose everything else. That’s the entire game with auto breeding.
Low Ryder Contribution to Offspring
| Auto Trigger | Locked — day-neutral flowering |
| Stature Influence | Variable — some phenos run compact, others revert to Chem stretch |
| Terpene Impact | Selected against — Corey Haim gas profile takes priority |
| Internode Spacing | Tighter in some phenos — structural improvement from auto side |
| Flowering Speed | ~100 days total, sprout to harvest |
Recessive Genetics
How the Auto Trait Locks
The autoflowering gene is recessive. The F1 cross (Corey Haim × Low Ryder) produced 100% photoperiod carriers. Inbreeding those carriers gave roughly 25% autoflowering offspring in the F2. From there, every generation was selected exclusively from the auto-flowering pool — refining terps, structure, and potency while ensuring the auto trigger remained fixed. By the time this line reached commercial release, the trigger is locked and the population breeds true for day-neutral flowering.
Terpene Architecture
Industrial Gas Profile
The Corey Haim cut’s volatile chemical signature — preserved through the inbreeding program into autoflower format.
🍋 Limonene
🌲 Myrcene
🪵 Humulene
Dominant Terpenes — Expected Expression
| β-Caryophyllene | Primary — black pepper, spice, garlic depth |
| Limonene | Co-dominant — ammonia-citrus, drives the cerebral rush |
| Myrcene | Supporting — earthy, musky, contributes the sedative body |
| Humulene | Trace — woody, savory, adds the garlic/burger funk |
The nose on the Corey Haim cut is not subtle. Hairspray. Aerosol chemicals. Raw garlic. An ammonia-rich lemon-pine burn that hits like industrial cleaner. This is the I-95 corridor’s definition of “gas” — the era when the measure of quality was solely how offensive the volatile sulfur compounds were to the uninitiated nose. If it didn’t make house guests uncomfortable, it wasn’t done.
Fair Warning — Carbon Filter Required
Stardawg Auto is not a discreet strain. The volatile sulfur compounds will saturate an entire facility during late flower. A carbon filter isn’t optional — it’s mandatory. The Corey Haim lineage reeks. Plan accordingly.
Phenotype Expressions
The Pheno Hunt
What the inbred population throws — and what you’re looking for in a pack.
The inbreeding program started with the Corey Haim cut and selected forward for the gas profile. The population isn’t uniform — you’ll see variation in structure, terp intensity, and how much the auto parentage influences the final plant. The hunt is for the individuals that stayed truest to the Corey Haim: dense, resinous, offensively loud, with that industrial chemical nose intact in autoflower format.
🫁 Iron Lung
The primary target. These are the individuals that retained the Corey Haim’s signature hairspray-garlic terpene profile while adopting a more manageable frame from the auto side. Dense, resin-encrusted buds on plants that don’t need the fifty bamboo stakes the original clone demanded. The gas is intact. The structure cooperates. This is the whole point of the project.
Frequency: ~50%
Terps: Hairspray, garlic, industrial chem
Structure: Stocky, tighter internodes than the clone
Yield: Med–high — dense spears
Effect: Cerebral rush → body-flattening sedation
💜 Purple Chem
The recessive anthocyanin expression from the Stardawg lineage. These individuals pair the Corey Haim’s industrial gas profile with deep lavender and violet coloration — genetic purple that isn’t temperature-dependent. The bag appeal is extraordinary. Contradicts the myth that purple cannabis is less potent — these hold full Chem-level intensity with elite visual presentation.
Frequency: ~25%
Terps: Full gas — industrial cleaner with color
Color: Deep lavender/violet — genetic, not cold
Yield: Medium — slightly lower than Iron Lung
Effect: Potent — full Corey Haim narcotic weight
🌿 Sativa Revert
A small percentage of the population leans hard into the Chem 4 grandmother — tall, stretchy, lanky architecture that wants support. More challenging in a small grow space, but these throwbacks can produce massive, forearm-sized colas that made Chem 4 a commercial legend in the NYC underground. Worth the extra effort if you have the room.
Frequency: ~15–25%
Terps: Chem 4-leaning — ammonia, pine, lemon
Structure: Tall, lanky — needs support
Yield: Potentially highest — big colas
Effect: Cerebral, soaring — Chem 4 head rush
“The Iron Lung is the target — Corey Haim gas on a plant that doesn’t require an engineering degree to keep upright. But don’t sleep on the Purple Chem if it shows up in your pack. That’s the kind of jar that ends conversations.”

Effect Profile
The Experience
Two-phase psychoactive event inherited from the Corey Haim cut.
The Stardawg Auto experience is a two-part event. The first wave is an immediate cerebral rush — mood-boosting, euphoric, soaring. The limonene-driven onset hits fast, with the kind of adrenaline-edged euphoria that the Chem 4 and Chem D lineages are famous for. The room gets brighter. Ideas feel better. There’s a manic quality to the initial onset that experienced Chem smokers recognize as the signature “head rush.”
Then it turns. The myrcene and caryophyllene catch up, and the second phase settles into full-body sedation. The Corey Haim cut was specifically described as “body-flattening” — the kind of narcotic weight that transitions a social evening into philosophical couch-lock and stargazing. This is headstash cannabis. It’s not a micro-dose. It’s not a “functional” smoke. It’s the kind of intensity that earned the Corey Haim cut its reputation as the Stardawg pheno that was “too much for most to handle.”

Environment, feeding, and expectations for the inbred auto population.
Environment Specifications
| Light Cycle | 18/6 or 20/4 — autoflower independent |
| Total Cycle | ~100 days sprout to chop |
| Ideal Medium | Living soil or coco/perlite blend |
| Container Size | 3–5 gallon final pot — start in final container |
| Temperature | 72–82°F day / 65–72°F night |
| Humidity | 55–65% veg → 40–50% late flower |
| Training | LST recommended. No HST — autos don’t recover. |
| Feeding | Careful with nitrogen — Chem lineage is sensitive. |
| Odor Control | Carbon filter mandatory. This reeks. |
Start in Final Pot
The fixed vegetative timeline of autos leaves no room for transplant recovery. Plant directly into your final 3–5 gallon container. No transplanting, no recovery period, no wasted days.
Easy on Nitrogen
The Chem lineage has always been a diva with nutrients. The Corey Haim cut’s offspring inherit that sensitivity. Light-medium feeding throughout, and err on the side of underfeeding if you’re unsure. Nutrient burn is the most common mistake with this line.
LST the Sativa Reverts
If you get a Sativa Revert pheno that stretches hard, tie it down early — week 2–3 — to open the canopy and manage height. The Iron Lung and Purple Chem phenos are compact enough to run without training in most setups.
Odor Management
We cannot stress this enough: carbon filter. Active carbon, properly sized for your space, replaced on schedule. The volatile sulfur compounds in late flower will saturate drywall, clothing, and anything else in the vicinity. This is not a stealth grow strain.
Global Context
The Stardawg Standard
How Stardawg became the international benchmark for “gas.”
Stardawg’s influence extends far beyond the I-95 corridor. In the UK, it became a cultural symbol for quality — the strain that defined what “gas” meant to an entire overseas market. JJ NYC himself noted the volume of seed requests from British growers, where the intense aroma and bag appeal made Stardawg a staple of the European exotic scene. When people in the UK think of elite American genetics, they think of Stardawg. That kind of global validation doesn’t happen by accident — it’s the result of decades of underground selection work from JJ NYC and the broader Top Dawg catalog.
Stardawg Auto makes that legacy accessible in a format that doesn’t require the infrastructure of a full-scale photoperiod operation. The 100-day cycle, the auto trigger, the easy difficulty rating — this is headstash genetics democratized for growers who don’t have warehouse space or the inclination to manage light cycles. The gas profile that defined a global market, now in seed form for anyone willing to pop a pack and hunt.

Where Chem 4 — and by extension, Stardawg — sits in the original Deer Creek lineage.
Original Chemdog Selections
| Chem 91 | Skunk, diesel fuel — fuel-heavy, the first pop |
| Chem D | Garlic, onion, burger — the G.O.B. profile |
| Chem 4 | Ammonia, pine-sol, industrial lemon — Stardawg’s mother |

Deer Creek, 1991
Thirteen seeds from a bag of “Dog Bud” bought at a Grateful Dead show in Indiana. That’s the origin of the entire Chemdog bloodline — Chem 91, Chem D, Chem 4, Chem Sister. Every gas-forward poly-hybrid in modern cannabis traces back to that parking lot. Stardawg Auto is a direct descendant, carrying the Chem 4 genetics through JJ NYC’s Stardawg cross and into a format that didn’t exist when those seeds were first discovered.
Final Word
A Legacy in Seed Form
The Stardawg Auto project traces a direct genetic line from a gravel parking lot in Indiana in 1991 to a 100-day autoflower in 2025. Thirteen bag seeds. The Chemdog bloodline. JJ NYC’s decade of preservation work. The Corey Haim cut — the most volatile, most potent selection from the Stardawg family. Crossed to Low Ryder for the auto trigger and inbred forward to lock the gas profile, the flowering mechanism, and the structural improvements into a single, commercially stable seed line.
This is not a novelty auto and it’s not a participation trophy. It’s the I-95 corridor’s industrial gas heritage in a format that completes its lifecycle in 100 days, requires no light cycle management, and rates easy to grow. Pop a pack, hunt for the Iron Lung, and find out why the Corey Haim cut earned its reputation as the Stardawg that was too much for most to handle.
This is headstash genetics, democratized.
