AK-47
AK-47 is the Serious Seeds cross of Colombian, Mexican, Thai, and Afghani lines released in 1992. The name refers to the strain's reliability rather than any aggressive effect — it is one of the most consistent seed lines in the European catalogue. Plants finish in roughly nine weeks indoors with a sweet floral terpene profile and a sativa-leaning high.

Terpene profile
The aromatic compounds below shape how AK-47 smells, tastes, and ultimately feels in the body.
- dominant
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- secondary
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- secondary
Pinene
Alert and pine-forward — associated with mental clarity and bronchodilation.
- minor
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.

Lineage
AK-47 traces to Colombian × Mexican × Thai × Afghani. The cross sits in the Serious / Sensi line family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for AK-47
These EC and NPK targets are starting points calibrated for the strain's Sativa lean and easy difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 0.9-1.1 EC
- Early flower
- 1.0-1.2 EC, NPK 2-2-3
- Mid flower
- 1.3-1.5 EC, NPK 1-3-4
- Late flower
- 1.1-1.3 EC
- Final week
- Plain pH-balanced water for the last 5-7 days.

What to expect through the grow cycle
AK-47 is documented with a 9-week flower and a longer stretch phase typical of sativa-leaning hybrids. The visual below maps a documented 13-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for AK-47 concentrate the most observational notes on the stretch window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for AK-47. Plants establish root structure, leaf canopy, and node count before flower triggering, with a easy difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-7)
- AK-47 is documented as having moderate stretch. Reports describe the plant roughly doubling in height during this phase as the sativa-leaning structure establishes its final flowering frame.
- Bud sites (weeks 8-9)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for AK-47note this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 10-11)
- Flowers thicken and calyxes fatten through this phase. Documented AK-47 runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 12)
- Trichomes transition from clear toward cloudy and amber. Reports for AK-47 describe the Caryophyllene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 13)
- Calyx swelling is documented as complete and the harvest window opens. Published AK-47 runs end here, within the 8-9 week flowering range reported by the breeder.

Common questions about AK-47
Why does AK-47 have measurable CBD?
The Colombian and Thai sides of the cross carry small but stable CBD expression, putting most phenotypes around one percent — high for a recreational sativa.
Is AK-47 strong?
It tests at the lower end of modern strains (around 18 percent THC), but the high is fast-onset and sativa-dominant, which makes it feel stronger than the lab numbers suggest.
