Where 9 Pound Hammer Comes From
9 Pound Hammer, also written 9lb Hammer, is a three-way cross of Gooberry, Hell’s OG and Jack the Ripper. Leafly and Allbud credit JinxProof Genetics. Other listings name TGA Subcool Seeds, and a Seedfinder-based note says TGA distributed the strain until 2019, which may explain the overlap in credits.
The name is a nod to the heft of the plant’s effect rather than a literal weight. Each parent contributes something. Gooberry adds a sweet, fruity berry flavor, Hell’s OG brings classic OG pungency and strength, and Jack the Ripper adds a bright citrus lift and some sativa influence.
Leafly reports the strain won at the 2014 High Times Cannabis Cup in Seattle, though that is a single-source claim here. Whatever its competition record, 9 Pound Hammer remained a regular in Pacific Northwest dispensaries and is a favorite for people who want a strong indica.
9 Pound Hammer Effects: What It Feels Like
9 Pound Hammer lives up to the name for many users. The first minutes bring a warm, happy settling in the head, and then the body effect arrives in force, with heavy limbs, loose muscles and a slow, sleepy mind.
This is an evening strain. It fits well for a late-night movie, a bath or going straight to bed. Smaller doses stay calm and pleasant, while larger ones can feel like a weighted blanket. People with low tolerance should treat it with respect, because the combination of high THC and strong indica genetics can knock out an afternoon.
9 Pound Hammer Terpenes, Aroma and Flavor
The smell blends sweet grape and berry with citrus, earth and a trace of fuel. It is richer and more candied than most OG-style strains, a reflection of the Gooberry parent.
On the inhale the flavor is fruity and sweet. The exhale is earthier and slightly peppery. Leafly lists myrcene as the dominant terpene, and caryophyllene and limonene are commonly seen alongside it. Actual lab profiles differ between growers.
- Myrcene: earthy, musky and herbal, also found in mango and hops
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
- Limonene: bright citrus, also found in lemon and orange peel
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.

Growing 9 Pound Hammer
- Difficulty: Moderate
- Flowering: 8–9 weeks
- Yield: Medium to high
- Height: Short to medium
- Environment: Indoor or greenhouse; outdoor in warm, dry climates
9 Pound Hammer is generally described as a compact, indica-leaning plant with dense buds. The density raises mold risk in damp conditions, which is a concern in the Pacific Northwest fall, so indoor growing or a greenhouse is safer. Growers recommend good airflow and some defoliation. Yield and flowering time depend on the cut.
Home-grow rules depend on the state: adults can grow at home in states such as California (six plants per residence), Michigan (12 per residence) and Oregon (four per household), while Washington and Illinois allow home growing only for registered medical patients. Check your state in our cannabis laws by state guide before you plant anything.
