Cannabis seeds
by Pyramid Seeds
Northern Lights by Pyramid Seeds is a feminised cannabis seed bred from rare, old-school Northern Lights phenotypes that most seed banks lost access to years ago. Where other versions of this classic Indica lean on modern crosses, Pyramid Seeds went back to the source — hunting down original NL genetics and stabilising them into a compact, resin-heavy plant that stays under 120cm and delivers up to 600g/m² indoors. If you've grown a Northern Lights before and thought "that was good but not quite the real thing," this is the version that might change your mind.
Every seed bank and their nan has a Northern Lights in the catalogue. That's the thing — the strain is so popular that it's been crossed, backcrossed, and diluted dozens of times over the past three decades. Pyramid Seeds took a different approach. These Spanish breeders tracked down an old, hard-to-find NL phenotype — one of those original cuts that made Northern Lights famous in the first place — and built their feminised line around it.
The result is a plant that behaves like you'd expect a proper old-school Indica to behave. She grows compact, rarely pushing past 100cm (though she can stretch to 120cm in optimal conditions), and puts all her energy into producing dense, resin-caked buds rather than wasting it on vertical growth. The natural robustness here is genuine — we've seen customers grow this in less-than-ideal setups and still pull respectable harvests. She adapts to soil, hydro, indoor, outdoor. Not fussy.
One honest limitation: because Pyramid Seeds worked with older genetics, you might find slightly more variation between plants than you'd get from a heavily stabilised modern hybrid. That's the trade-off for authenticity. Most growers consider it a fair deal.

Northern Lights from Pyramid Seeds grows into a squat, bushy plant with tight internodal spacing — classic Indica structure. The branches stay close to the main stem, which makes her a solid choice for smaller tents or sea-of-green setups where you're packing multiple plants into a limited footprint. During flower, the buds swell into fat, dense nuggets that get absolutely plastered in sticky trichomes. By late flower, the resin production is visible to the naked eye — the buds glisten under grow lights like they've been dipped in sugar.
The compact structure also means less time spent on training. You can top her once or twice if you want to even out the canopy, but she doesn't need heavy LST or scrogging to perform. That said, if you do run a SCROG, she responds well — those short, sturdy branches fill a net nicely.
This is where the old-school genetics really shine through. Northern Lights from Pyramid Seeds produces a rich, piney aroma with earthy undertones — that classic NL smell that anyone who grew up around cannabis in the '90s will recognise immediately. When you crack open a cured bud, there's a sweetness underneath the pine that rounds out the profile. According to competitive data, when consumed through a dry herb vaporiser, the dominant flavour leans heavily into strong pine notes with a smooth, slightly spicy exhale.
The smell during flowering is moderate. She's not the stealthiest strain on the planet, but she's nowhere near as pungent as a Skunk or Cheese. A decent carbon filter will handle it without breaking a sweat. If you're growing in a shared space, you'll want that filter running from week 3 of flower onwards — that's when the terpenes really start pumping.
We've been selling cannabis seeds since 1999, and Northern Lights in some form has been in the catalogue for nearly all of that time. Here's what we've picked up from two decades of customer feedback on this strain specifically:
First, don't overwater. Northern Lights has a compact root system that sits in a relatively small pot, and soggy roots will slow her down more than almost anything else. Let the top 2–3cm of soil dry out between waterings. Second, she responds brilliantly to a simple top at the 4th or 5th node — this opens up the lower branches and evens out bud development without stressing the plant. Third, if you're growing in a small tent (60x60 or 80x80), you can comfortably fit 4 plants in 10-litre pots and still hit that 600g/m² ceiling under a proper 600W light.
Research published in PMC has shown that cannabis varieties including Northern Lights can demonstrate significant yield differences based on light spectrum and photoperiod adjustments (PMC10004775). If you're running LEDs, consider adding some far-red spectrum during the last two weeks of flower — a study on Northern Lights specifically observed changes in cannabinoid percentages under modified light treatments (PMC12092679).
If you're weighing up Northern Lights against other Indica options, here's how she compares. Against a pure Afghan or Hindu Kush, Northern Lights typically offers better yields and a more refined flavour profile — those landrace strains are interesting but can be inconsistent. Against something like a Critical or Big Bud, Northern Lights trades a bit of raw yield for better resin production and a more complex terpene profile. She won't outproduce a Critical on sheer weight, but the quality of what she does produce is hard to beat.
Compared to other Northern Lights versions from different seed banks, the Pyramid Seeds version distinguishes itself through that rare phenotype selection. Most modern NL seeds are several generations removed from the original — Pyramid went back to find genetics that are closer to the source. You can taste the difference.
| Trait | Northern Lights (Pyramid) | Typical Modern NL | Critical Mass / Big Bud |
|---|---|---|---|
| Genetics | Rare original NL phenotype | Crossed / hybridised NL | Indica hybrid |
| Height | 80–120cm | 100–150cm | 100–140cm |
| Yield (indoor) | Up to 600g/m² | 400–550g/m² | 500–700g/m² |
| Resin Production | Very high | Moderate to high | Moderate |
| Difficulty | Beginner-friendly | Beginner-friendly | Beginner-friendly |
| Flavour | Pine, earth, sweet | Pine, mild | Sweet, citrus |
Complete your setup with a propagation kit for germination and a carbon filter to keep the pine aroma contained during flower. If you're after a Sativa to complement this Indica grow, Amnesia from Pyramid Seeds makes a solid pairing — different effect, same reliable genetics from the same breeder.
Yes — Northern Lights is one of the most forgiving strains you can start with. She handles temperature fluctuations, minor feeding mistakes, and inconsistent watering better than most. Pyramid Seeds' version is particularly robust thanks to the hardy original phenotype they selected.
Northern Lights is a strong Indica with noticeable resin production. According to research on Northern Lights cannabinoid profiles, THC percentages can vary based on light treatment and growing conditions (PMC12092679). Expect a potent, resin-heavy harvest when grown well.
Moderately. She produces a distinct piney, earthy aroma from mid-flower onwards, but she's not as overpowering as Skunk or Cheese varieties. A carbon filter on your extraction fan will handle the smell for indoor grows without any issues.
Under a 600W light with proper conditions, you can expect up to 600g/m². Most growers report harvests in the 400–600g/m² range depending on pot size, training technique, and light quality. She punches above her weight for such a compact plant.
She does — Northern Lights adapts well to both soil and hydro setups. In hydro, you'll typically see slightly faster vegetative growth and can push yields toward the upper end of that 600g/m² range. Just watch your EC levels; she doesn't need heavy feeding.
Most plants stay around 80–100cm, with some phenotypes stretching to 120cm. This makes her a strong choice for growers working with limited vertical space — she'll fit comfortably in a standard 160cm tent with room for a light above.
Northern Lights typically finishes flowering within 8–9 weeks under a 12/12 light cycle. Research on Northern Lights flowering initiation confirms she responds predictably to standard photoperiod changes (PMC12987174). She's not one to keep you waiting.
