9 Pound Hammer
Breeder: Jinxproof Genetics
A legendary indica powerhouse bred by Jinxproof Genetics, 9 Pound Hammer crosses the fruity, resin-heavy Gooberry (Afgoo x Blackberry) with the structurally superior Jesus OG Kush (Hell's OG x Jack the Ripper). Winner of the 2014 High Times Cannabis Cup in Seattle and 1st Place Indica at the 2014 Santa Cruz Cup, this strain is named for its knockout sedative effects. Dense, hammer-shaped buds coated in early-onset trichomes deliver an overwhelming grape-candy and lime terpene profile with devastating full-body relaxation.
Lineage & Genetics
Cross: Gooberry x Jesus OG Kush
Gooberry (Afgoo x Blackberry) is a resin-heavy indica that contributes the fruity grape-berry terpene profile, extreme trichome coverage, dense bud structure, and the Blackberry lineage responsible for autumn purple coloring. Jesus OG Kush (Hell's OG x Jack the Ripper) provides structural vigor, enhanced growth speed, and the OG Kush backbone that adds depth to the effects and improves overall plant architecture.
Terpene Profile
Myrcene — 35–40% of total terpenes; drives the heavy sedation and earthy-musky base notes. Enhances THC absorption for the knockout stone effect.
Caryophyllene — 20–25% of total terpenes; provides spicy depth and CB2 receptor interaction for pain relief. Adds peppery warmth to the flavor.
Limonene — 15–18%; contributes grape-candy sweetness and seasonal variation — more prominent in summer grows for a brighter, more uplifting quality.
Pinene — Herbal pine freshness that adds complexity to the inhale and may slightly offset sedation.
Linalool — Floral lavender character that enhances the sedative and calming properties.
Aroma: Overwhelming grape-candy and lime sweetness with deep berry undertones. Breaking buds releases intense fruity vapors — grape Hi-Chew and ripe melon — over an earthy, musky base. The nose is loud and immediately recognizable.
Flavor: Grape Hi-Chew and melon candy dominate the palate with lime brightness on the inhale. The exhale carries earthy depth and subtle spice. A 4–6 week cure brings out the full candy-fruit complexity that defines the strain's legendary taste profile.
Effects & Experience
Onset: Fast-acting euphoric rush that hits within minutes. Initial mood elevation and happiness before the physical sedation takes hold.
Overwhelming full-body relaxation that builds into deep, immobilizing sedation. The initial euphoric onset gives way to heavy-limbed couch-lock and irresistible sleepiness. At moderate doses, the experience begins pleasantly relaxed; at higher doses, it becomes purely narcotic.
Duration: 2–4 hours; sedative effects can persist longer and frequently lead to deep, restorative sleep.

Grower's Notes
9 Pound Hammer is one of the fastest-finishing heavy indicas available, delivering commercial-scale yields with minimal fuss. Originally distributed through TGA Genetics until 2019, all authentic genetics now come directly from Jinxproof's Dank Bank. The prominent phenotype expresses Gooberry-dominant traits — rock-hard buds with oversized calyxes smothered in early resin production and stunning autumn colors at harvest.
Genetics & Phenotypes
The cross of Gooberry (Afgoo x Blackberry) with Jesus OG Kush (Hell's OG x Jack the Ripper) produces two main expressions. The sought-after Gooberry-dominant pheno pushes dense, hammer-like nuggets with extreme trichome coverage and deep purple/orange autumn coloring. The Jesus OG-leaning pheno shows more traditional Kush structure with enhanced vigor and slightly greener coloration. Both finish fast and yield heavily.
Training & Structure
Displays Kush-style growth with the ability for immense size, but handles intense late-veg pruning exceptionally well. Top once or twice before flip and apply LST or SCROG to spread the canopy. This naturally bushy plant benefits enormously from horizontal training — expect 20–30% yield increases by opening lower bud sites to light. The compact stature (under 4 feet indoors) makes it ideal for low-clearance grows and SOG setups.
Feeding & Nutrients
A heavy feeder during mid-to-late flower. Increase phosphorus and potassium substantially once buds begin stacking. Maintain pH between 6.0–6.5 in soil. The dense bud structure demands good airflow and calcium/magnesium supplementation to prevent interior mold and bract deficiencies. Back off nitrogen early in flower to encourage the natural purple fade.
Environment & Climate
Thrives in warm, Mediterranean-style climates outdoors with harvest in early-to-mid October. Indoors, maintain 68–80°F during lights-on. To maximize the signature autumn colors and purple expression from the Blackberry lineage, drop nighttime temps 8–10°F below daytime during the final 2–3 weeks of flower. Keep humidity at 45–50% during late flower to protect the ultra-dense buds from botrytis.
Terpene Expression
Myrcene dominates (35–40% of total terpenes), driving the heavy sedation. β-Caryophyllene (20–25%) provides spicy depth and CB2 receptor interaction for pain relief. Limonene (15–18%) contributes the grape-candy sweetness. Seasonal variation is notable: summer grows produce more limonene and pinene (brighter, more uplifting), while fall/winter grows boost myrcene and caryophyllene for deeper sedation.
Harvest Timing
The fast 50–60 day flower window is forgiving, but dialing harvest timing maximizes the desired effect profile. For the signature knockout stone, wait until 20–30% of trichomes show amber coloration. Harvesting earlier (mostly cloudy, minimal amber) will preserve more of the initial euphoric onset before sedation takes over. Resin production begins early in flower — frost is visible by mid-veg on vigorous plants.
Drying & Curing
The dense, rock-hard bud structure requires patience during drying. Hang whole plants or large branches in 60°F / 60% RH for 10–14 days minimum. The tight calyxes trap moisture; rushing this stage invites mold and hay smell. A 4–6 week cure in jars brings out the grape Hi-Chew and melon candy flavors that define the strain's legendary taste profile.
Best Uses
Strictly an evening/nighttime strain. The full-bodied stone leads to immediate relaxation followed by deep, restorative sleep. Medical patients report excellent results for chronic pain, PTSD, muscle tremors, insomnia, and stress. The high myrcene-to-caryophyllene ratio makes it particularly effective for inflammation and physical discomfort. Also an outstanding extraction strain — the extreme resin production and complex terpene profile translate beautifully into concentrates, rosin, and hash.
History & Origin
9 Pound Hammer was bred by Jinxproof Genetics and originally distributed through TGA Genetics (Subcool's The Dank) until 2019. It made a major competition impact in 2014, winning 1st Place Indica at the Santa Cruz Cup and taking a High Times Cannabis Cup award in Seattle the same year. The strain is named for its knockout sedative effects — hitting like a 9-pound hammer. All authentic genetics now come directly from Jinxproof's Dank Bank. The strain remains one of the fastest-finishing heavy indicas available and a benchmark for grape-candy terpene profiles in indica breeding.
