The specs in one line: 18-23% THC, <1% CBD, 7-8 weeks flowering, 450-550 g/m² reported. Best indoor or outdoor. moderate grow.

Lineage: Gooberry × Hells OG × Jack the Ripper — three strains that don't obviously belong together, yet the cross lands squarely indica-dominant with a THC range of 18–23% and a surprisingly short 7–8 week flower window. Yields sit in the 450–550 g/m² range indoors, which is solid for a plant that finishes this fast. The aroma leans fruity up front with a grounding earthy finish — nothing flashy, just a clean, consistent nose that carries through to the cure.

Difficulty is rated moderate, so first-timers aren't the target here, but any grower with a run or two under their belt should manage it without much drama. It performs in both indoor and outdoor environments, giving you flexibility if your setup changes season to season.

Best suited for intermediate growers who want a hard-hitting indica that wraps up before most strains hit peak stretch.

With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

9 Pound Hammer delivers THC levels of 18-23%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing 9 Pound Hammer

9 Pound Hammer is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 7-8 weeks with yields of 450-550 g/m². Plants typically reach 80-150 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

9 Pound Hammer features a fruity, earthy terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, 9 Pound Hammer is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
