How to Grow AK47 Autoflower: A Fast Sativa Auto
AK47 Autoflower is a fast, easy autoflowering take on the legendary AK-47, bred by crossing it with a Lowryder (ruderalis) line. This 65% sativa auto pairs a bright citrus, mango and spicy flavor with a medium 16-18% THC, and a creative, focused, energizing effect, finishing a whole crop in just 8-10 weeks from seed.
Because it is an autoflower, it is one of the simplest ways to grow a classic AK: no light-schedule changes to manage, a compact plant, and a quick turnaround that lets you fit more than one harvest into a season. It keeps the energizing, cerebral character AK-47 is famous for, now in a beginner-friendly, speedy package.

Growing an Autoflower
An autoflower does not need a change in light schedule to bloom. Instead of switching to 12/12 like a photoperiod plant, AK47 Autoflower starts flowering on its own after a few weeks, purely on age, and runs its whole life cycle in about 8-10 weeks from seed to harvest. You can keep it under a long day of around 18-20 hours of light from start to finish.
Because the clock is always ticking, the golden rule is to avoid any check to its growth. Start the seed in its final pot rather than transplanting, since transplant shock costs an auto days it cannot make up. Keep any training gentle, low-stress tucking rather than heavy topping, and feed lightly. Being feminized, every seed grows into a flowering female, so there is no need to sex the plants.
Climate and Where to Grow It
AK47 Autoflower does best in a temperate climate with long, sunny days and good airflow. The ideal range is around 70-80°F (21-27°C). It stays compact, so it fits small tents and discreet outdoor spots easily, and its quick finish makes it forgiving in regions with a short or unpredictable season.
Its biggest outdoor advantage is flexibility: because it flowers on age rather than daylight, you are not tied to one planting window. In the northern hemisphere you can sow from April onward, pull a first harvest in mid-summer, and run a second crop into July through mid-October, which makes it a true all-season plant in a warm climate.
Keep humidity in check to protect the resinous buds: around 55-60% early on, nearer 40% in flower, and down to about 30% by harvest. Steady warmth and plenty of light across the whole short cycle are what let this auto reach its full potential.
Feeding Schedule (EC Guide)
Autoflowers are smaller and faster than photoperiod plants, so they want a lighter touch. Feed gently, follow the plant’s lead, and taper off for the final flush so the citrus-and-mango flavor comes through clean and the smoke finishes smooth. The ranges below are a guide; with an auto, err on the low side.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed, start in the final pot |
| Vegetative growth | 0.8-1.2 | Short veg, raise nitrogen gently |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
AK47 Autoflower starts flowering on its own a few weeks in and finishes its whole cycle in 8-10 weeks from seed, far faster than a photoperiod plant. As a sativa-leaning auto it stays compact but fills in dense, trichome-coated buds that carry the energizing AK character. There is no flip to manage, so you simply keep the light steady and let it run.
Yields are good for an auto: around 350-450 g/m² indoors and up to 600-700 g per plant in a strong outdoor season, depending on light, pot size and canopy health. Give it a well-sized pot from the start so the roots never stall, keep the canopy open, and harvest when most trichomes have turned cloudy for the fullest expression.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry stops the resinous buds staying damp in the middle while the outside dries out, which protects both the citrus-spicy aroma and the trichome coat.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings the citrus, mango and spicy notes forward and smooths out the smoke, which is well worth the patience even on a strain this quick to grow.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. AK47 Autoflower is a resinous, trichome-coated plant, so its trim is excellent for making dry sift, bubble hash or rosin. That gives you a bonus run of citrusy, spicy concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
AK47 Autoflower has a bright, moreish profile: zesty citrus and juicy mango lifted by a fresh, peppery spice. It is a lively, mouth-watering flavor rather than a heavy or dark one, and a good cure really rounds out that citrus-mango-spice character in the jar and on the inhale.
Those flavours trace straight back to its AK-47 heritage, which is known for a pungent, skunky, spicy aromatic profile. The citrus and tropical mango notes sit on top of that classic AK backbone, with the fresh, slightly peppery spice giving the aroma its characteristic edge. It is this complex, recognisable AK scent that has kept the line popular for decades.
Effects and Best Use
With its medium 16-18% THC and 65% sativa make-up, AK47 Autoflower delivers a bright, energizing, cerebral experience. It is reported as creative and focused, the kind of clear, uplifting lift that sparks ideas and conversation, with a comfortable body feel underneath and a tendency to bring on a pleasant case of the munchies.
That makes it versatile: a creative, functional lift during the day, or an easy, sociable option in the evening when you still want to feel engaged. The mix of a classic AK head, a fast and simple autoflower grow and a tasty citrus-spice flavor is exactly why this one stays a catalogue favourite.
Common Problems and Pro Tips
The single most important thing with any autoflower is to never stall its growth, because it cannot make up lost time on a fixed clock. Start the seed directly in its final pot instead of transplanting, keep it in healthy, living soil or a well-mixed medium, and don’t overfeed a small, fast plant. An auto that gets checked simply stays small and yields less.
Keep training gentle. Heavy topping or aggressive techniques can set an auto back, so stick to low-stress tucking of branches to open the canopy and let light reach more bud sites. Good airflow and sensible humidity through its short flower also keep the resinous buds clean and healthy right up to harvest.
As a pro tip, make its speed work for you: because it finishes in 8-10 weeks and flowers on age, you can run back-to-back crops or stagger plantings for a near-continuous supply. Keep the feed light, run a clean plain-water flush at the end, then follow the trichomes rather than the calendar and cure for three to four weeks for the best citrus-spice flavor.
FAQ
Is AK47 Autoflower really an autoflower?
Yes. It is a true autoflower, bred by crossing AK-47 with a Lowryder ruderalis line, so it flowers automatically on age rather than on a light change. You do not switch to 12/12, and it runs its whole life cycle in about 8-10 weeks from seed, which makes it fast and simple to grow.
How much THC does AK47 Autoflower have?
It is a medium-THC strain, testing at around 16-18%. That gives it a strong but manageable, mostly cerebral effect rather than an overwhelming one. Combined with its 65% sativa genetics, the result is bright, creative and energizing, which makes it a good all-rounder for day or evening use.
How long does AK47 Autoflower take to grow?
About 8-10 weeks from seed to harvest, since it flowers automatically on age. That short cycle is its biggest draw: in a warm climate you can run more than one crop a year, sowing from April and harvesting through summer into mid-October outdoors, or back-to-back indoors.
What does AK47 Autoflower taste like?
It has a bright, lively flavor: zesty citrus and juicy mango lifted by a fresh, peppery spice. Those notes sit on top of the classic AK-47 backbone, which is known for a pungent, skunky, spicy aroma. A good cure really brings that citrus-mango-spice character forward in the jar.
Is AK47 Autoflower good for beginners?
Yes. It is beginner-friendly: compact, fast and forgiving, with no light-schedule changes to manage and no need to sex the plants. The main rule is to avoid stalling its growth, so start it in its final pot, keep training gentle and feed it lightly through its short cycle.
How much does AK47 Autoflower yield?
Yields are good for an auto: around 350-450 g/m² indoors and up to 600-700 g per plant in a strong outdoor season. Results depend on light, pot size and canopy health, so give it a good-sized pot from the start and plenty of light to get the most from it.
