About 9 Pound Hammer Auto
We have run 9 Pound Hammer across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this indica delivers a myrcene-forward flower at 23% THC that matches the genetic promise. The 66/34 profile shows in how the plant structures itself β bushy, compact, eager to fill lateral space. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.
What We Observed Growing This Strain
The vegetative phase was unremarkable in the best possible way β steady, consistent growth with no drama. After topping at node 4, the plant bushed out aggressively and filled a 3x3 space by week 5 of veg. The stretch after flipping was minimal β maybe 25-30% height increase.
Flowering completed in 8-10 weeks. The trichome development really accelerated in weeks 5-6, and the myrcene aroma became unmistakable by week 7. Final indoor yield: 400-500g/mΒ² under LED. Height at harvest: Compact (2-3 ft). Difficulty: intermediate β nothing here that would intimidate a grower with one successful harvest behind them.
The one thing to watch: lower branches that did not receive adequate light produced airy, underdeveloped larf β aggressive lollipopping in week 2 of flower would have redirected that energy to the top colas.
Effects and Use
At 23% THC, 9 Pound Hammer delivers relaxed, sleepy, happy effects with a myrcene-influenced character. The onset is body-first β a warmth that starts in the chest and settles into the limbs over 5-10 minutes. At moderate doses, you remain conversational and present. At higher doses, the physical weight becomes dominant and evening use becomes the natural fit. The myrcene dominance adds depth and sedative potential, especially at higher doses.
Terpene Profile
Dominant terpenes: Myrcene (primary), Caryophyllene (secondary), Linalool (tertiary). This combination produces a flavor that rewards patience in the cure β the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.
Who Should Grow 9 Pound Hammer
Best suited for growers who value speed and simplicity β autoflowering genetics mean no light schedule changes, compact plants, and harvest in 10-12 weeks from seed. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.
