Original Auto Northern Lights Cannabis Seeds by Fast Buds
Original Auto Northern Lights is an autoflowering cannabis seed from Fast Buds that brings the legendary Northern Lights genetics into a faster, more forgiving format. Northern Lights has been a staple since the 1980s — an indica-dominant classic that practically defined what a relaxing evening smoke should taste and feel like. Fast Buds crossed that heritage with ruderalis genetics to create an autoflowering version that keeps the deep, stoney indica character but finishes in roughly 9 weeks from germination. If you want a no-fuss grow with a proper payoff, this is where you start.
Why Original Auto Northern Lights Deserves a Spot in Your Grow
Northern Lights is the strain your mate's older brother grew in the '90s and still talks about. It's been crossed into hundreds of hybrids, won more cups than anyone can count, and remains a benchmark for indica-leaning genetics. The problem with the original photoperiod version? It needs a strict 12/12 light cycle flip to flower, which means more equipment, more attention, and more room for error if you're just getting your feet wet.
Fast Buds solved that. Original Auto Northern Lights doesn't care about your light schedule. She'll start flowering on her own, typically around week 3-4, and push through to harvest in about 9 weeks total. That's seed to dried bud in just over two months. For indoor growers running 18/6 or 20/4 light cycles, that means more harvests per year without the hassle of separate veg and flower rooms. For outdoor growers, it means you can plant later in the season and still finish before autumn turns ugly.
The honest limitation here: autoflowers generally produce less per plant than their photoperiod cousins. You can't extend the vegetative phase to grow a monster tree. But at up to 600g/m² indoors, Original Auto Northern Lights punches well above what most autos deliver. And the trade-off in simplicity is genuinely worth it, especially if you're on your first or second grow.
Growing Original Auto Northern Lights — What to Expect
This strain grows in classic indica fashion: compact, bushy, with a fat main cola and sturdy side branches. Plants top out at around 120cm, which makes her manageable in a tent as small as 60x60cm, though we'd pick an 80x80 tent if you've got the space — your canopy will thank you. The internodal spacing is generous enough that airflow isn't an issue, which means less worry about mould during the dense bud development in late flower.
One thing we've seen growers appreciate: Original Auto Northern Lights handles cold and wet climates unusually well. If you're growing outdoors in northern Europe where summers are short and unreliable, this strain won't fold at the first sign of a damp week. She's tough. Genuinely tough — not marketing-brochure tough.
- Germinate your seeds using the paper towel method or directly in a small pot of lightly moistened soil. Keep temperatures around 22-25°C.
- Transplant seedlings into their final container (11-15 litre pots work well) within the first week. Autoflowers don't love being transplanted late, so get them settled early.
- Run an 18/6 or 20/4 light cycle from start to finish. No need to switch to 12/12 — she'll begin flowering automatically around week 3-4.
- Feed lightly during the first two weeks, then gradually increase nutrients as she enters pre-flower. Autoflowers are sensitive to overfeeding, so go easy.
- Watch for the stretch during early flower — she may gain 30-50% of her final height in the first two weeks of bloom.
- Harvest around week 9 from germination. Check trichomes with a jeweller's loupe: mostly milky with a few amber means peak potency for that heavy indica stone.
- Dry in a dark, ventilated space at 18-20°C and 55-60% humidity for 7-10 days, then cure in glass jars for at least two weeks.
Aroma, Flavour and Resin Production
Crack open a jar of properly cured Original Auto Northern Lights and you'll get hit with that unmistakable Northern Lights nose: spicy, peppery, with an earthy backbone that smells like a walk through a pine forest after rain. There's a mild fruitiness underneath — nothing tropical or loud, more like dried berries mixed into damp soil. It's smooth rather than sharp, which is part of what made the original Northern Lights so universally loved. Nobody ever complained that Northern Lights was "too much."
The resin production is worth mentioning on its own. Buds come out sticky and coated in trichomes, making Original Auto Northern Lights a top pick if you're interested in making hash or dry sift. The classic Northern Lights hash is legendary for a reason, and this autoflowering version delivers the same raw material. If you've got a set of bubble bags or a pollen press, you'll get excellent results from the trim alone.

If you want that deep, classic indica stone with old-school flavours, Original Auto Northern Lights is the pick. Gorilla Cookies Auto leans heavier on modern potency and sweeter terps, while Purple Lemonade Auto is the one to grab if you want something colourful and citrusy. All three are from Fast Buds, all three are solid — but Northern Lights is the heritage choice.
Complete your setup: pair Original Auto Northern Lights seeds with a propagation kit for reliable germination, and grab a carbon filter if you're growing indoors — she's not the loudest strain, but 600g/m² of resinous bud will still make itself known. If you're planning to make hash from the harvest, a set of bubble bags will put all that trichome production to proper use.
Why Original Auto Northern Lights Is Worth Growing
We've been selling cannabis seeds since we first opened the doors in Amsterdam back in 1999, and Northern Lights has never left the bestseller list. Not once. There's a reason for that. It's the strain people come back to after chasing every new hype cross — because it just works. The smoke is clean, the grow is easy, and the results are consistent.
Original Auto Northern Lights takes that reliability and removes the last remaining barrier: the light cycle management. New growers lose plants to bad light schedules more often than they'd like to admit. With an autoflower, that entire variable disappears. You set your timer to 18/6 on day one and forget about it. She handles the rest.
The one thing to watch: don't over-water and don't over-feed. Autoflowers have a compressed life cycle, which means they can't recover from stress the way a photoperiod plant can. If you stunt her in week 2, she doesn't have time to bounce back. Keep things simple — good soil, moderate nutrients, consistent light — and she'll reward you with dense, resinous buds that smell like the 1990s in the best possible way.
Frequently Asked Questions
What are the effects of Original Auto Northern Lights?
Original Auto Northern Lights delivers a powerful indica stone with deep physical relaxation and couch-lock. She's traditionally associated with evening use — the kind of smoke where you sit down and don't get up for a while. Expect heavy body effects rather than cerebral stimulation.
Is Original Auto Northern Lights as good as the photoperiod version?
The flavour profile stays true to the original: spicy, earthy, with that signature mild fruitiness. Potency is strong for an autoflower. The main difference is yield per plant — photoperiod versions can be vegged longer for bigger plants, but the auto compensates with a much faster total cycle time.
How long does Original Auto Northern Lights take from seed to harvest?
About 9 weeks from germination to harvest. That's roughly 63 days total. Some phenotypes may run a few days longer, so always check trichome colour with a loupe before chopping rather than going strictly by the calendar.
Can I grow Original Auto Northern Lights outdoors in a cold climate?
Yes — this is actually one of her strong points. Fast Buds bred her to handle cold and wet conditions better than most autoflowers. She's a solid choice for northern European outdoor grows where summers are short and unpredictable. Just make sure she gets enough direct sunlight.
Is Original Auto Northern Lights good for making hash?
Absolutely. The resin production on this strain is heavy, and the trichome coverage extends well onto the sugar leaves. She's a classic hash-making strain — Northern Lights hash has been prized for decades. Use bubble bags or dry sift techniques for the best results.
How many seeds come in a pack of Original Auto Northern Lights?
Each pack contains 3 feminised autoflowering seeds. All seeds are from Fast Buds and are bred to produce female plants only, so no need to sex your plants or worry about males pollinating your grow.
What size pot should I use for Original Auto Northern Lights?
11-15 litre pots are the sweet spot. Go too small and you'll restrict root development, which directly limits yield. Go too large and you risk overwatering. Plant directly into the final container within the first week — autoflowers don't respond well to late transplanting.
