AK Full Auto Feminized Cannabis Seeds by Sumo Seeds
AK Full Auto is a feminized autoflowering cannabis seed that races from germination to harvest in just 9-10 weeks, producing dense, resinous buds on compact plants rarely exceeding 1 metre. Bred by Sumo Seeds, this hybrid crosses their prized Ultimate AK cut with ruderalis genetics — keeping the full spicy-sweet AK flavour profile while ditching the photoperiod dependency. If you want AK dankness without the scheduling headaches, this is the one.
Why AK Full Auto Seeds Deserve a Spot in Your Grow
AK Full Auto seeds produce plants that start flowering before most photoperiod AK varieties have even finished vegging. That's not marketing fluff — it's the ruderalis genetics doing their job. These plants don't wait for a light-cycle change. They just go. You germinate, you pot up, and roughly 9-10 weeks later you're trimming. For growers working with limited space, tight schedules, or both, that's a genuine advantage.
The thing we'd flag straight away: don't let the compact size put you off. Mature plants stay under a metre indoors and outdoors, which sounds modest until you see the flower-to-leaf ratio. Sumo Seeds specifically bred for bud density over plant height, and it shows. Most of the plant is flower. Tight, chunky clusters that, according to Sumo Seeds, can push yields to 400g/m² indoors. Outdoor growers can expect 70-90g per plant — respectable for an auto that finishes this quickly.
The honest limitation? Like all autos, you can't extend the vegetative phase if something goes wrong early on. A rough start — overwatering, nutrient burn, transplant shock — costs you proportionally more than it would with a photoperiod strain. Our advice: start in the final pot, keep feeding gentle in the first two weeks, and let the plant do its thing. AK Full Auto is forgiving once it gets going, but those first 10 days matter.

How AK Full Auto Compares to Photoperiod AK Strains
The classic AK-47 lineage has been around for decades, and photoperiod versions still dominate seed-bank catalogues. So why go auto? Speed and simplicity. A photoperiod AK-47 typically needs 8-9 weeks of flowering alone — plus 4-6 weeks of veg before you even flip the lights. That's 12-15 weeks minimum. AK Full Auto does the entire run in 9-10 weeks, no light schedule changes required.
| Feature | AK Full Auto (Sumo Seeds) | Typical Photoperiod AK-47 |
|---|---|---|
| Total Grow Time | 9-10 weeks | 12-15 weeks |
| Light Schedule | 18/6 or 20/4 throughout | 18/6 veg, 12/12 flower |
| Height | Under 1m | 1-1.5m+ |
| Indoor Yield | Up to 400g/m² | 350-500g/m² |
| Training Flexibility | LST recommended, HST risky | Full HST/LST/SCROG |
| Multiple Harvests per Season | Yes — 2-3 runs possible | Typically 1 |
The yield ceiling on a photoperiod AK is higher if you max out veg time and run a full SCROG. But AK Full Auto's speed means you can potentially pull 2-3 harvests in the same calendar window. Over a full season, total output can actually match or beat a single photoperiod run — and you're spreading your risk across multiple crops instead of betting everything on one.
Aroma, Flavour, and What to Expect from AK Full Auto Bud
Sumo Seeds kept the full AK terpene profile intact here, and you can tell. Crack open a cured bud and you get that unmistakable spicy-sweet AK nose — sharp, slightly floral, with an earthy undertone that sticks to your fingers. It's not subtle. If you've grown AK genetics before, you'll recognise it immediately. If you haven't, think warm spice cabinet meets damp forest floor.
The smoke follows through on what the nose promises. That complex blend of sweet and spicy carries into the flavour, with a lingering peppery finish. According to research published in Frontiers in Plant Science, terpene profiles — the aromatic compounds responsible for these flavours — may contribute to a broader entourage effect alongside cannabinoids (PMC11870048). The varied terpene mix in AK genetics is part of what's made this lineage so enduringly popular.
Effects come on fast. An energetic, cerebral onset hits almost immediately, then gradually settles into a warm, mellow body feeling. It's the kind of progression that works equally well mid-afternoon or early evening — stimulating enough to keep you present, relaxing enough that you won't be pacing around the kitchen.
How to Grow AK Full Auto Seeds
- Germinate directly or in a damp paper towel. Soak seeds for 12 hours in a glass of water, then transfer to damp kitchen paper between two plates. Taproots usually emerge within 24-72 hours.
- Plant into the final container immediately. Autos don't like transplanting. Use a 7-11 litre pot with well-draining soil or coco. Plant the germinated seed 1-1.5cm deep, taproot pointing down.
- Run 18/6 or 20/4 light from day one. No need to switch to 12/12 — AK Full Auto flowers automatically regardless of light schedule. More light hours means more energy for bud production.
- Keep feeding light for the first 2 weeks. Seedlings don't need heavy nutrients. Start at quarter-strength and build up gradually as the plant enters its rapid growth phase around week 3.
- Apply low-stress training (LST) from week 2-3. Gently bend and tie down the main stem to expose lower bud sites to light. Avoid topping or high-stress techniques — autos don't have time to recover from aggressive training.
- Watch for pre-flowers around week 3-4. AK Full Auto begins flowering early. Switch to bloom nutrients when you see the first pistils forming at the nodes.
- Flush for the final 7-10 days before harvest. Run plain pH'd water to clear residual nutrients from the growing medium. This improves the final flavour and smoothness of the smoke.
- Harvest at 9-10 weeks post-germination. Check trichomes with a jeweller's loupe — mostly cloudy with a few amber heads is the sweet spot for a balanced effect.
Complete your setup: If you're running AK Full Auto in a tent, pair it with a complete grow kit that includes extraction, carbon filtration, and proper lighting. A pH meter and basic nutrient set will also make a noticeable difference to final yield and bud quality on a fast-finishing auto like this.
AK Full Auto Cannabis Seeds: Safety and Interactions
This product is sold as cannabis seeds for adult collectors and growers aged 18 and over. Cannabis is a psychoactive plant, and responsible use starts with understanding what you're working with.
According to Cannabis sativa (Hemp) Seeds, Tetrahydrocannabinol and related compounds, exposure to high concentrations of THC could lead to psychological events and gastrointestinal disorders, including sedation and anxiety (PMC5665515). Side effects reported by users of AK-lineage strains include dry mouth, dry eyes, and — at higher doses — anxiety or restlessness.
A moderate drug interaction exists between cannabis and anticoagulants such as Warfarin. If you use prescription medication — particularly blood thinners, CNS depressants, or MAOIs — consult your doctor before using cannabis products. According to the National Academies of Sciences, Engineering, and Medicine, the current evidence base for cannabis health effects is still developing, and individual responses vary significantly (PMC7915118).
Frequently Asked Questions
How long does AK Full Auto take from seed to harvest?
9-10 weeks from germination to harvest. That includes both the vegetative and flowering phases — AK Full Auto starts producing buds automatically around week 3-4, with no light schedule change needed.
What yield can I expect from AK Full Auto indoors?
Sumo Seeds rates indoor yields at up to 400g/m² under optimal conditions. In a basic setup with moderate lighting, 200-300g/m² is more realistic. Outdoor growers can expect 70-90g per plant.
Can I top or FIM AK Full Auto plants?
We'd avoid it. Autos have a fixed life cycle, and high-stress techniques cost recovery time they can't spare. Stick with low-stress training — bending and tying — to open up the canopy without slowing growth.
Does AK Full Auto smell strongly during flowering?
Yes, significantly. The spicy-sweet AK terpene profile is pungent from around week 5 onwards. A carbon filter and proper extraction fan are not optional if you need to keep things discreet.
Is AK Full Auto good for beginner growers?
It's one of the better autos for beginners. The compact size keeps things manageable, the fast turnaround means you see results quickly, and the genetics are robust enough to handle minor feeding mistakes. Just don't transplant — start in the final pot.
What light schedule should I use for AK Full Auto?
18 hours on, 6 hours off is the standard. Some growers run 20/4 for extra growth. Since it's an autoflower, you never need to switch to 12/12 — the plant flowers based on age, not light cycle.
How does AK Full Auto compare to other AK autoflower seeds?
The main differentiator is Sumo Seeds' Ultimate AK parent — a selected cut rather than generic AK genetics. This gives AK Full Auto a more pronounced terpene profile and denser flower structure than many budget AK autos. The 400g/m² yield ceiling is also above average for the category.
Can I grow AK Full Auto outdoors in northern Europe?
Yes. The 9-10 week lifecycle means you can start in May and harvest by mid-July, well before autumn weather sets in. The compact size also makes it easy to move pots indoors if conditions turn rough. Expect 70-90g per plant outdoors.
