Auto AK 47 by Serious Seeds – High-Yielding Autoflowering Sativa Hybrid

Auto AK 47 by Serious Seeds is your fast-track passport to a high-octane sativa experience, packed into a compact, no-fuss autoflowering plant that delivers quality buds in just 10–12 weeks from seed to harvest.

Worried your grow will be a chaotic mess of uneven plants, weak yields, or endless waiting? Maybe you’ve tried autos before and ended up with puny plants or inconsistent results. You want something that actually performs — without needing a PhD in pH meters and nutrient charts.

That uncertainty kills the vibe. You’re left stressed, doubting every move, and dreading another disappointing harvest. It’s exhausting just thinking about it — especially when all you want is a smooth, reliable grow that lets you enjoy the process, not fight it.

Meet Auto AK 47: the no-drama, high-reward autoflower that grows strong, finishes fast, and rewards you with dense, crystal-covered buds and a soaring sativa high. This is Serious Seeds’ legendary AK-47 genetics, perfected into an automatic version that’s tough, consistent, and ready when you are — no light cycle changes, no guesswork, just results.

Compact Size, Maximum Discretion

Auto AK 47 stays small and stealthy, making it perfect for balconies, closets, or tight indoor spaces. It reaches a manageable height of 0.75–1.00 m (2.46–3.28 ft), so it won’t tower over your setup or draw unwanted attention. Its bushy, compact structure fills out evenly without wild stretching, and the strong smell is contained thanks to its fast cycle — less time in the grow phase means less odor to manage. Grow it in a 20 L pot and it stays under control, blending in like any other houseplant until it’s time to harvest.

Total Control from Seed to Smoke

• Autoflowers from seed to harvest in just 70–80 days — no light schedule changes needed.
• Consistent genetics mean all plants grow uniformly, so no weak links in your crop.
• Hardy structure tolerates minor nutrient imbalances and short dry spells without stress.
• Compact size lets you grow multiple plants in limited space with full control over environment.
• Resinous buds develop quickly, giving you full visibility and confidence in your progress.

How to Grow Auto AK 47 Successfully

Start strong and keep it simple. This autoflower thrives on a low-stress approach — no topping, no FIM, just steady growth.

1. Germinate seeds in a moist paper towel or starter cube at 22–25 °C (71.6–77 °F).
2. Transplant to its final 18–27 L pot as soon as roots appear — autos hate being moved.
3. Use well-aerated soil or coco with Biocanna Kit for balanced nutrition.
4. Provide 18–20 hours of light daily; keep temperatures at 22–26 °C (71.6–78.8 °F) in veg.
5. Reduce humidity to 40–50% in flowering to protect dense buds from mold.
6. Support heavy colas with soft ties if needed, especially outdoors in wind.
7. Flush with plain water 7–10 days before harvest for a smoother smoke.

Quick overview: autoflowering · Serious Seeds · 70–80 days · low difficulty · ideal for indoor tents and outdoor balconies.

Safe start: Germinate with confidence — all seeds pop fast. Transplant gently to final pot to avoid shock.

• Use jiffy pellets or starter cubes for clean germination.
• Keep humidity high (70%) until first true leaves appear.
• Transplant when taproot is ~1 cm (0.4 in) long.
• Choose a 20 L pot for optimal root development.
• RootFast by Atami boosts early root growth and resilience.

Stable seedling: Keep it simple and steady — no overfeeding, no stress.

• Water lightly when topsoil feels dry.
• Start mild nutrients in week 2 (¼ strength).
• Maintain 22–25 °C (71.6–77 °F) for strong growth.
• Avoid defoliation — let the plant build foliage naturally.
• Use Bactomatik Rex to strengthen root microbiome.

Directed growth: Let it stretch naturally — this sativa auto loves light and space.

• Provide 18–20 h light daily with full-spectrum LEDs.
• Use LST to open up canopy and improve light penetration.
• Keep nutrients balanced — avoid excess nitrogen in late veg.
• Ensure good airflow to prevent humidity buildup.
• Stick to soil or coco; avoid hydro for beginners.

Efficient flowering: Support the stretch and feed for resin, not size.

• Expect pre-flower signs around day 20–25.
• Reduce humidity to 40–50% to protect dense buds.
• Support heavy colas with soft plant ties.
• Use bloom boosters like Rhino Skin Advanced Nutrients from week 3.
• Watch trichomes: harvest when mostly milky for energetic high.

Harvest, drying and curing: Patience pays off in flavor and smoothness.

• Flush 7–10 days before harvest to clear nutrients.
• Cut branches and hang in dark, 18–22 °C (64.4–71.6 °F), 50–60% RH.
• Dry for 7–10 days until stems snap.
• Cure in jars for 2–4 weeks, opening daily for first week.
• Store in airtight containers away from light and heat.

Frequently Asked Questions

How discreet is Auto AK 47 for indoor growing?

While it has a strong smell during flowering, its short 70–80 day cycle limits odor exposure. Use a carbon filter and good ventilation to stay under the radar.

Can I grow Auto AK 47 outdoors in a cold climate?

Yes — its hardy genetics tolerate cooler temps, but aim for a sunny spot and plant after the last frost. Harvest before heavy autumn rains to avoid mold.

Does this strain need training?

LST (low-stress training) helps maximize yield, but avoid topping or FIM — autoflowers don’t recover well from aggressive pruning.

What kind of high does Auto AK 47 give?

A powerful, uplifting sativa high — great for creativity, socializing, or daytime focus. Not sedating, so it won’t lock you to the couch.

How much yield can I expect in a small grow tent?

In a 60x60x160 cm (23.6x23.6x63 in) tent with 4 plants, expect 160–300 g (5.6–10.6 oz) total. Use 20 L pots and 250–400W LED for best results.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Auto AK 47 stands out because it actually delivers on the sativa promise — no lazy buzz, just pure, clean energy. I ran six plants in my balcony tent last summer, 20 L pots, Biobizz nutrients, and they all finished within two days of each other. No hermies, no stalling, just solid, resin-dripping colas. I love how it smells like fresh lemon peel with a spicy kick — it fills the room when you open the jar. My trick? I start LST early, gently bending the main stem down to create a flat canopy. That way, every bud gets equal light and I max out yield without going vertical. It’s become my go-to for quick, reliable harvests when I want something uplifting without the wait.
