9 Pound Hammer Seeds

Genetics & effects

9 Pound Hammer is a feminised, indica-dominant selection presented in the Outback Seed Bank catalogue. Its lineage combines Gooberry × Hell’s OG × Jack the Ripper, with an estimated 80% indica and 20% sativa profile. The listed cannabinoid range is 18–24% THC and up to 0.5% CBD, although expression can vary between plants and growing environments.

Myrcene, caryophyllene and limonene shape a rich aromatic profile. Sweet berry and grape lead the way, followed by citrus, lime, pine and earthy notes. Individual experiences are subjective, but some people describe the effects as deeply relaxed, happy or euphoric, sometimes becoming sleepy or accompanied by a stronger appetite. Others may notice a brief uplift before the heavier character becomes more prominent.

Growing in Australia

This intermediate-level cultivar may suit hot, humid, hot, dry and temperate Australian conditions. Its relatively short flowering period can be useful where autumn weather changes quickly. Local conditions differ widely, so growers should consider humidity, rainfall, daylight, airflow and overnight temperatures when planning a site.

Keep the canopy open enough for steady air movement, especially in humid coastal districts. In hot, dry areas, consistent irrigation and a moisture-retaining mulch may help limit stress. Always check the rules applying in your state or territory before obtaining or germinating cannabis seeds.

Indoor

Indoors, plants may reach up to 120 cm. A flowering period of approximately 7–9 weeks makes this a comparatively quick option. Gentle canopy management can help distribute light across productive sites, while adequate spacing may reduce the risk of stagnant humidity around dense flowers.

• Indoor height: up to 120 cm
• Indoor yield: up to 500 g/m²
• Flowering: approximately 7–9 weeks

Yield figures are catalogue estimates rather than assured outcomes. Lighting, environment, plant health, experience and phenotype all influence the final result.

Outdoor

For outdoor cultivation in Australia, spring planting generally falls between September and November. Plants may reach up to 180 cm where root space, sun and weather are favourable. Choose a bright position with good drainage and airflow, and allow room for lateral branching.

In humid regions, regular inspection and sensible spacing are important because compact flowers may be more vulnerable to mould. In exposed dry districts, wind protection and stable soil moisture can support more even development without leaving the root zone waterlogged.

• Outdoor height: up to 180 cm
• Outdoor yield: up to 800 g per plant
• Preferred conditions: hot humid, hot dry or temperate

Harvest

Australian outdoor harvest commonly falls between March and May, depending on planting time, latitude, phenotype and seasonal conditions. Rather than relying only on the calendar, assess flower maturity and monitor weather forecasts as autumn approaches. Indoor plants are generally ready after their 7–9 week flowering window. Actual timing, colour, aroma and production will vary with the environment and individual plant.
