9 Pound Hammer is a potent, Indica-dominant hybrid with a reputation for delivering a heavy, relaxing high — perfect for unwinding after a long day. It's a cross between Gooberry, Jack the Ripper, and Hell's OG, a combination that results in a strain with both a delicious flavour profile and robust physical effects.

Flowering Time and Yield

Indoor growing: Flowering takes around 50–60 days (7–9 weeks) — a relatively short window for such a potent strain — with yields typically ranging from 450–550g/m².

Outdoor growing: Expect harvest from late September to early October depending on climate, with yields of up to 600g or more per plant under good conditions.

Growing Tips

9 Pound Hammer is notably resistant to powdery mildew, making it easier to manage for indoor growers dealing with humidity concerns. Topping plants early in the vegetative stage helps control height and encourage bushier growth — useful for growers working with limited space and looking to maximise yield.

It thrives in temperate climates but adapts well to controlled indoor environments too. Being Indica-dominant, it doesn't demand excessive light, though a standard 18/6 vegetative and 12/12 flowering cycle will get the best results. Nutrient needs are moderate — avoid overfeeding, as this strain is prone to nutrient burn.
