AK-47 Auto

Description from Serious Seeds

This auto-flowering version of the iconic AK-47 strain brings the legendary genetics of Serious Seeds into a more manageable, faster-growing format. Designed for legal growers, these stocky, bushy plants reach heights of 75–100 cm when mature. With a sativa-dominant profile, they emit a rich aroma blending sweet citrus and spiced fruit notes that linger in the air. The plants are heavy with resin and deliver the signature high potency of the original AK-47 strain.

Unlike photo-period strains, Auto AK-47 begins flowering automatically after 70 days, eliminating the need to manipulate light cycles. Indoors, it typically yields 45–70 grams per plant, making it a reliable choice for growers seeking consistency and efficiency.

This feminized autoflowering strain is best suited for temperate climates and carries the lineage of AK-47 x Ruderalis.

Outdoor Growing Timeline

Autoflowers can be planted in multiple waves throughout the season to achieve staggered harvests. The timeline includes several key stages to ensure healthy growth and a successful yield.

Stage 1: Germination
April – July
Wait for: warmer days, no frost, stable temperatures
Watch for: cold nights, overwatering, weak early light

Stage 2: Seedling / Transplant
1–2 weeks after sprouting
Wait for: strong light, mild weather, protected start
Watch for: slug damage, stretching, transplant stress

Stage 3: Vegetative Growth
Weeks 2–5
Wait for: long bright days, healthy root growth
Watch for: stunting, nutrient burn, pest pressure

Stage 4: Flowering
Weeks 5–8+ depending on cultivar
Wait for: steady sunshine, decent airflow, dry spells
Watch for: mould, heavy rain, snapped branches

Stage 5: Harvest
Weeks 8+ or summer to early autumn
Wait for: mature trichomes, swollen buds, finished aroma
Watch for: bad weather, bud rot, harvesting too early
