Royal AK Autoflower Cannabis Seeds
Royal AK Autoflower is an autoflowering feminised cannabis seed from Royal Queen Seeds that packs AK-47's legendary genetics into a compact, fast-finishing package. A cross of AK-47 and ruderalis, she carries the Afghani, Thai, Mexican, and Colombian lineage that made the original a household name — minus the photoperiod fuss. From seed to harvest in roughly 9 weeks, with around 15% THC and yields averaging 100 grams per plant. If you want the AK-47 profile without babysitting a light schedule, this is your seed.
How Many Seeds Do You Need?
Royal AK Autoflower comes in packs of 1, 3, 5, or 10 seeds. Growing indoors in a small tent? Three seeds fills an 80x80 cm space nicely. Running a full 120x120? Grab the 10-pack — you'll use them across two or three cycles anyway, and the per-seed price drops. If you've never grown autos before, start with a 3-pack so you can learn the plant's rhythm without too much at stake.
Why Royal AK Autoflower Seeds Deserve a Spot in Your Grow Room
The original AK-47 earned its reputation through sheer genetic firepower — four landrace lines from Afghanistan, Thailand, Mexico, and Colombia blended into one vigorous sativa-dominant hybrid. The problem? Photoperiod AK-47 wants attention. She needs a strict 12/12 light flip, she stretches tall, and she takes her time finishing. Royal Queen Seeds solved that by crossing the AK-47 with ruderalis genetics, creating Royal AK Autoflower: same intense, musky aroma profile, same balanced stone-meets-cerebral effect, but on autopilot.
We've sold Royal Queen Seeds genetics since the early days, and this one keeps coming back into carts for a simple reason — it actually delivers on the "easy to grow" promise. Autos can be hit or miss from some seed banks. Weak ruderalis crosses produce airy, underwhelming buds. Royal AK Autoflower doesn't have that problem. The plant fills out properly, develops dense flower sites, and the terpene profile is genuinely pungent. You'll smell her through the tent fabric by week five. That's the Afghani and Colombian genetics doing their thing.
The honest limitation: 100 grams per plant is a realistic average, not a headline number. Photoperiod AK-47 grown by an experienced hand in a dialled-in setup will out-yield this auto every time. But if you're after speed, simplicity, and a reliable harvest without needing a timer and a PhD in light-cycle manipulation, the autoflower version is the smarter pick. It's the best AK-47 autoflower seed for growers who value their time.
Aroma, Flavour, and What to Expect from Royal AK Autoflower
Royal AK Autoflower fills the room with an intense musk — earthy, slightly sweet, with a sharp spice note that sits somewhere between sandalwood and black pepper. It's not subtle. If you're growing without a carbon filter, your neighbours will have questions by mid-flower. The smoke carries that same earthy depth with a hint of floral sweetness on the exhale.
The effect profile sits right in the middle. The sativa-dominant genetics from the Thai and Colombian lines bring a cerebral, uplifting onset, while the Afghani indica side anchors it with a physical relaxation that builds gradually. At 15% THC, she's not going to flatten you — this is a comfortable, functional level that works for a late afternoon without writing off the evening. Compared to something like Royal Haze Auto, which leans harder into the sativa headspace, Royal AK Autoflower feels more centred and grounded. If you want something even more body-focused, Royal Kush Auto would be the direction to look.
Growing Royal AK Autoflower Seeds: Cultivation and Yield
Royal AK Autoflower reaches 80–100 cm in height, making her a solid fit for indoor tents from 60x60 cm upward. She doesn't need training to stay manageable, though a bit of low-stress training (LST) in the first three weeks can open up the canopy and improve light penetration to lower bud sites. Don't top her — autos don't recover from high-stress techniques the way photoperiods do, and you'll lose more yield than you gain.
Flowering time runs approximately 56–70 days from seed to harvest. That's the full lifecycle, not just the bloom phase. She'll show pistils by week three without any light schedule change — just keep her on 18/6 or 20/4 from start to finish. The plant responds well to a consistent environment: 20–25°C, 50–60% relative humidity during veg, dropping to 40–50% in flower.
One thing we'd flag: go easy on nutrients. Autoflowers have a smaller root system and shorter lifecycle than photoperiods, so they're more sensitive to overfeeding. Start at half the recommended dose on your nutrient schedule and work up only if the plant asks for it. Burnt tips in week two means you've already set yourself back — and with a 9-week total lifecycle, there's no time to recover from mistakes.

Complete your setup: if you're running Royal AK Autoflower indoors, pair her with a Dark Box grow tent and a carbon filter — the intense musk this strain produces during flower is no joke. Already sorted for hardware? Northern Light Auto from Royal Queen Seeds makes a great companion plant in the same tent: similar height, similar timeline, different terpene profile. Harvest variety without extra effort.
How to Grow Royal AK Autoflower Seeds
- Germinate your seeds using the paper towel method or directly in a small pot of moist, light soil. Tap roots typically appear within 24–72 hours.
- Transplant the seedling into its final container once the tap root is 1–2 cm long. Use a 7–11 litre pot — autos don't like being transplanted twice, so go straight to the final size.
- Set your light schedule to 18 hours on, 6 hours off. Keep this consistent from seedling through harvest. No need to switch to 12/12.
- Begin feeding at half-strength nutrients around week two, once the first true leaves are established. Increase gradually only if the plant shows no signs of nutrient burn.
- Apply gentle LST from week two to three by bending the main stem sideways and securing it with plant ties. This opens the canopy without stressing the plant.
- Monitor humidity: aim for 55–65% during the seedling and early veg phase, dropping to 40–50% once flowers form to prevent mould.
- Begin flushing with plain water 7–10 days before harvest. Trichomes should be mostly milky with a few turning amber — that's your harvest window for balanced effects.
- Dry in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least two weeks. The terpene profile improves noticeably with proper curing.
Royal AK Autoflower vs Other Royal Queen Seeds Autos
| Strain | Genetics | THC | Height | Seed to Harvest | Best For |
|---|---|---|---|---|---|
| Royal AK Autoflower | AK-47 x Ruderalis | ~15% | 80–100 cm | ~9 weeks | Balanced effect, classic genetics |
| Northern Light Auto | Northern Light x Ruderalis | ~14% | 80–120 cm | ~9 weeks | Body-focused relaxation, easy grow |
| Royal Haze Auto | Haze x Ruderalis | ~15% | 80–120 cm | ~10 weeks | Cerebral, sativa-dominant effect |
Royal AK Autoflower sits between the other two in terms of effect. Northern Light Auto leans heavier on the indica side — great for evening use, but less versatile. Royal Haze Auto goes the other direction with a more stimulating sativa profile, though she takes an extra week to finish. If you want one seed that covers the middle ground and finishes fast, Royal AK Autoflower is the pick we'd make.
Frequently Asked Questions
How long does Royal AK Autoflower take from seed to harvest?
Around 9 weeks total — roughly 56 to 70 days depending on your growing conditions. That's the full lifecycle from germination to chop day, not just the flowering phase. Keep the environment stable and she'll stay on schedule.
What yield can I expect from Royal AK Autoflower indoors?
The realistic average is about 100 grams per plant. You can push this slightly higher with good light, proper LST, and dialled-in nutrients, but don't expect photoperiod-level harvests from any autoflower.
Do I need to change the light cycle for Royal AK Autoflower?
No. That's the whole point of autoflowering genetics. Keep her on 18/6 or 20/4 from seed to harvest. She'll start flowering on her own around week three regardless of light schedule.
Is Royal AK Autoflower suitable for first-time growers?
Yes — she's one of the more forgiving autos we carry. The main thing to watch is overfeeding. Start nutrients at half strength and only increase if the plant looks hungry. Beyond that, she mostly takes care of herself.
Can I grow Royal AK Autoflower outdoors?
Absolutely, as long as you're in a warm climate with consistent temperatures above 15°C. She stays compact at 80–100 cm, so she won't attract attention. Outdoors, she'll follow the same 9-week timeline regardless of season.
How does Royal AK Autoflower compare to photoperiod AK-47?
Same genetic lineage, different format. Photoperiod AK-47 yields more and can grow taller, but requires a 12/12 light flip and takes longer to finish. Royal AK Autoflower trades some yield for speed and simplicity — no light schedule changes needed.
Does Royal AK Autoflower smell strong during flowering?
Very. The Afghani and Colombian genetics produce an intense, musky aroma that builds through flower. If you're growing indoors without a carbon filter, everyone in the house — and possibly the neighbours — will know about it.
