AK48 Feminised Seeds by Nirvana Seeds

AK48 feminised seeds are a four-way landrace cross from Nirvana Seeds that flowers in just 7 to 9 weeks — fast for a strain carrying Colombian Gold, Thai, Mexican, and Afghani genetics. You get the broad genetic backbone of the classic AK family without the drawn-out flowering window that usually comes with sativa-heavy lineages. Expect dense, trichome-coated buds, a fruity-floral nose, and yields between 400 and 500 grams per square metre indoors. We've stocked Nirvana Seeds since the early days of the shop, and AK48 has been a consistent seller for over a decade.

AK48 Genetics: Four Landrace Lines in One Seed

AK48 feminised seeds carry genetics from four distinct landrace varieties, each contributing something specific to the final plant. Colombian Gold brings uplifting sativa character — it's one of the original South American landraces that shaped the cannabis scene in the 1970s. Thai adds another sativa dimension, historically valued across Southeast Asia for its vigour and resinous flowers. Mexican genetics contribute adaptability and growth speed. Then there's the Afghani backbone — the indica element responsible for the compact structure, heavy resin production, and the resilience that makes AK48 shrug off conditions that would stress less robust genetics.

The AK family of strains has been around since the 1990s, and the lineage has earned its reputation through sheer consistency. AK48 specifically was bred by Nirvana Seeds to capture that classic AK profile while trimming the flowering time down. Where some AK-lineage strains push 10 to 12 weeks, AK48 wraps up in 7 to 9. That's a meaningful difference if you're running multiple cycles per year or growing in a climate with a short outdoor season.

What Does AK48 Smell and Taste Like?

Crack open a cured jar of AK48 and you'll get a wave of sweet fruit layered over a floral base — think ripe citrus with a hint of spice underneath. The terpene profile leans on myrcene (earthy, musky, fruity), caryophyllene (spicy, peppery), and limonene (citrus, lemon). There's also carene adding a sweet, cedar-like undertone and traces of ocimene bringing a fresh herbal edge. The smoke is smooth for a mid-range THC strain, and the fruity-floral aroma translates well into the flavour. Not the loudest terp profile you'll ever encounter — strains like Critical or Northern Lights hit harder on the nose — but it's pleasant, clean, and won't overwhelm a small drying space.

AK48 Feminised Seeds: Growing Specs and Yield

Each pack contains 5 feminised seeds. Feminised means every seed that germinates should produce a flowering female plant — no need to identify and cull males. That alone saves you time, space, and the headache of discovering a male at week four.

How to Grow AK48 Feminised Seeds

AK48 is one of those strains we'd hand to a first-time grower without hesitation. The Afghani genetics give it a sturdy frame and natural resistance to mould and pests, so it forgives the kind of mistakes that would flatten a finicky sativa. That said, it still rewards attention. Here's how to get the most out of your 5 seeds.

1. Germination. Use the paper towel method: place seeds between two damp (not soaked) sheets of kitchen paper on a plate, cover with a second plate, and keep in a warm spot around 22-25°C. Taproots typically appear within 24 to 72 hours.
2. Seedling stage. Transplant into small pots (0.5L) with a light, airy soil mix. Keep humidity around 65-70% and light on an 18/6 cycle. Don't overwater — the number one seedling killer we see.
3. Vegetative growth. AK48 stays compact, so you won't need aggressive training. A light topping or LST (low-stress training) after the 4th or 5th node opens up the canopy and pushes more bud sites into the light. Maintain 18/6 lighting. Veg for 3-5 weeks depending on your space.
4. Flip to flower. Switch to 12/12 lighting. AK48 flowers in 7 to 9 weeks — most phenotypes finish closer to 8. Watch for the stretch in the first two weeks of flower; the plant may gain 30-50% height.
5. Feeding. During veg, a balanced NPK feed works fine. In flower, increase phosphorus and potassium. AK48 isn't a heavy feeder, so err on the side of less rather than more. Overfeeding shows up as burnt leaf tips — pull back immediately if you see it.
6. Harvest. Check trichomes with a jeweller's loupe. When most trichomes shift from clear to milky with a few amber ones appearing, it's time. 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.

AK48 Yield: What to Realistically Expect

Nirvana Seeds lists AK48 at 400 to 500 grams per square metre indoors, and in our experience that's accurate — provided you're running decent lighting (400W HPS minimum or equivalent LED) and feeding properly. Under a 600W setup in a 1.2m x 1.2m tent with 4 plants, you're looking at the upper end of that range. Outdoors, yield depends heavily on your climate and season length, but the compact structure and fast flowering make AK48 a solid pick for northern European growers who need to harvest before autumn rains set in.

One honest note: AK48 at 14-16% THC sits in the moderate range. If you're chasing 25%+ THC monsters, this isn't your strain. But that moderate potency is actually a selling point for plenty of growers — it's approachable, functional, and you can smoke a full joint without being glued to the sofa. For a first grow especially, a forgiving plant that actually finishes on time and produces decent weight beats a temperamental high-THC strain that stalls at week 6.

AK48 Terpene Profile

Myrcene dominates, which is typical for indica-leaning hybrids. Caryophyllene and limonene round things out with spice and citrus. The overall nose is sweet and fruity with an earthy base — pleasant in the grow room, not overpowering in a small flat.

Why AK48 Feminised Seeds Are a Reliable First Grow

We get asked "what should I grow first?" at least a few times a week. AK48 comes up in that conversation regularly, and here's why: it combines genuine genetic depth with a forgiving growth habit. The four-way landrace cross gives it hybrid vigour — that natural resilience you get when you combine genetics from different parts of the world. Colombian, Thai, Mexican, and Afghani varieties evolved under wildly different conditions, and that diversity translates into a plant that handles temperature swings, humidity fluctuations, and the occasional missed feed without drama.

The 7 to 9 week flowering time is the other big factor. Longer-flowering strains test your patience and your environment control. Every extra week in flower is another week where mould, pests, or nutrient lockout can derail things. AK48 gets in and gets out. You'll have trimmed, dried bud in your jars roughly 12 to 14 weeks from germination if you keep veg short. For a first-timer, that fast turnaround builds confidence — and you'll learn more from completing two quick cycles than from one drawn-out grow that goes sideways at week 10.

The one thing to watch: AK48 can stretch noticeably in early flower. If you're growing in a small tent (60x60 or similar), flip to 12/12 before the plant fills more than half the vertical space. Otherwise you'll be fighting to keep colas away from the light.
