Northern Lights is one of the most influential cannabis strains ever bred — a pure Indica legend from the 1980s that underpins hundreds of modern hybrids and still sets the standard today. This guide covers everything: effects, THC content, flowering time, yield, and the difference between all six variants from Pyramid Seeds — including CBD and Autoflowering versions. (Also commonly searched as: northern lights canabis, northern lights cannibis, northern lights weed, northern lights stain — same iconic strain.)
The Northern Lights Collection from Pyramid Seeds includes six variants: the classic Northern Lights Feminized, the Auto Northern Lights, the Northern Lights CBD, the Auto Northern Lights CBD, and the Northern Lights × Runtz from the Gold Line — each with its own profile, all built on the same stable Indica genetics at the core.
What makes Northern Lights so special?
Genetics, history, and a terpene profile that has proven itself over four decades.
Northern Lights emerged in the early 1980s on the US West Coast from a cross of Afghani and Thai genetics. By the mid-1980s the strain had reached Amsterdam, won the Cannabis Cup multiple times, and shaped an entire generation of breeders. Pyramid Seeds has cultivated this line for over two decades — with a 2nd place finish at the Spannabis Cannabis Champions Cup 2007 in the Hydro category as its best-known accolade.
What sets Northern Lights apart from other classics is exceptional stability. Predictable growth, consistent terpene profile (earthy, resinous, pine), reliable THC window of 20–22 %. Growers who've run Northern Lights once know exactly what they're getting next time. As a cannabis strain, it's also firmly Indica — compact structure, fast flowering, deep body-centred effects with minimal cerebral stimulation.
Northern Lights effects, THC level and terpene profile
Everything you need to know before choosing your variant.
The Northern Lights strain effects are consistently body-focused: a fast-onset physical relaxation that builds into deep calm, muscle release, and — at higher doses — sedation. The high Myrcene content in the terpene profile amplifies this. THC level: 20–22 % in the classic feminized and Auto versions; up to 27 % THC in the Northern Lights × Runtz Gold Line cross. Northern Lights THC content has remained remarkably consistent across decades of cultivation — one of the reasons it became the reference Indica for so many breeders.
Is Northern Lights indica or sativa? It's a near-pure Indica — Afghani landrace genetics dominate the structure, growth pattern, and effect profile. The Thai influence adds a subtle resinous sweetness to the aroma without the sativa stretch. This makes Northern Lights cannabis seeds ideal for indoor setups where compact, manageable plants are a priority.
All Northern Lights variants in detail
Northern Lights – Feminized (The Classic)
Northern Lights Feminized is the benchmark — photoperiod, 55-day flowering time, up to 500 g/m² indoors. The effect is deeply body-centred: fast onset, pleasant physical weight, long-lasting relaxation without overwhelming cerebral stimulation. Discreet smell during flowering makes it ideal for indoor setups where low odour is a priority. Robust genetics, tolerant of beginner errors — Northern Lights remains the most reliable Indica in the catalogue.
- Effects: THC 20–22 %, deep body stone, stress relief, sleep support
- Yield: Up to 500 g/m² indoor, outdoor harvest typically late September in the UK
- Best for: Growers who want maximum yields and the purest Northern Lights character — photoperiod, predictable, proven.
- Grow tip: Use Northern Lights as the reference plant in your setup. Its predictable structure and consistent flowering time make it the best benchmark in the grow — if something's off in the tent, compare to your Northern Lights first.
Auto Northern Lights – Autoflowering
Auto Northern Lights delivers the same genetics without a light schedule — ready in 70 days from germination, up to 100 cm tall, up to 500 g/m² indoor. The 20–22 % THC level is exceptional for an autoflowering strain — comparable to the classic version. In the UK, the short cycle allows two outdoor runs per season: first sow in April/May, second in June/July. No late-season weather risk, no light management, robust Ruderalis cross.
- Effects: THC 20–22 %, deep Indica body effect, relaxation, sedating
- Yield: Up to 500 g/m² indoor; compact outdoor plants, 2 harvests possible per UK season
- Best for: Beginners to autoflowering, discreet projects, multiple harvests per year.
- Grow tip: Don't transplant — autoflowering plants are sensitive to root stress. Sow directly into the final container size (12–15 L) and leave them there.
Northern Lights CBD
Northern Lights CBD carries the full terpene profile of the original — earthy sweetness, pine resin, spice — at 10–15 % CBD and 7–12 % THC. The effect is relaxing and body-centred, but without the intensity of the classic version. Ideal for daily use, for users who appreciate the Northern Lights character but want to stay functional, and for anyone seeking CBD-rich genetics with genuine strain identity rather than a neutral profile.
- Effects: CBD 10–15 %, THC 7–12 %, relaxing, clear-headed, daily use
- Best for: Daily use without a heavy high. Northern Lights character in relaxed mode — easing stress and tension without sedation.
- Grow tip: CBD strains harvest slightly earlier than THC-dominant ones — check trichomes from week 8 and harvest when most are still milky white for a clearer, less sedating profile.
Northern Lights CBD – Feminized
Northern Lights CBD Feminized carries the same full terpene profile — earthy, resinous, pine — with 10–15 % CBD and 7–12 % THC. Relaxing and body-focused without the intensity of the high-THC classic. This is one of the best options for CBD beginners who want genuine strain character rather than a generic neutral-tasting variety. Photoperiod means you control timing, and the stable NL genetics make it highly forgiving to grow.
- Northern Lights CBD effects: CBD 10–15 %, THC 7–12 %, relaxing, clear, daily use
- Best for: Daily use without a strong high. NL character in relaxed mode.
- Grow tip: Check trichomes from week 8. Milky white = clearer effect. Amber = heavier, more body-focused.
Auto Northern Lights CBD – Autoflowering
Auto Northern Lights CBD combines everything: CBD-rich profile, autoflowering genetics, ready in approx. 70 days without a light schedule. 10–15 % CBD, 7–12 % THC — Northern Lights terpene profile in its most accessible form. Perfect for discreet indoor projects that prioritise fast harvest and relaxing effects without an intense high.
- Auto Northern Lights CBD effects: CBD 10–15 %, THC 7–12 %, relaxing, clear, fast harvest
- Best for: Beginners to CBD autoflowering. No light schedule, NL character, ready in 70 days — the easiest variant in the entire NL family.
- Grow tip: Sow directly into the final container (10–12 L) — no transplanting for autos. CBD strains are more sensitive to overfeeding than THC-dominant varieties.
Northern Lights × Runtz – Gold Line
Northern Lights × Runtz is the modern interpretation of the classic — from Pyramid Seeds' Gold Line. The Runtz cross introduces a fruity, sweet terpene profile into the earthy NL base, at up to 27 % THC and 65 days flowering. For experienced growers who want the proven Indica body effect of Northern Lights combined with a contemporary fruity aroma.
- Effects: THC up to 27 %, intense body effect, fruity terpene profile
- Best for: Experienced growers who want NL stability with modern Runtz character.
- Grow tip: The Runtz side brings a little more energy into the grow — expect slightly taller plants than classic NL. Apply LST early to manage canopy.
Which Northern Lights variant is right for you?
Six variants, one strain character — but different profiles for different goals.
If you want maximum yields and the purest NL character, go with the Northern Lights Feminized — photoperiod, 55 days, up to 500 g/m². If you want to harvest fast without a light schedule — or plan multiple runs outdoors in the UK — the Auto Northern Lights gives you the same 20–22 % THC in 70 days. If you want the NL character daily without an intense high, Northern Lights CBD is your answer (10–15 % CBD, photoperiod). And if you want CBD profile and autoflowering in one package, Auto Northern Lights CBD is the most beginner-friendly variant in the whole family — ready in 70 days, no light schedule. For NL stability with a modern terpene upgrade, Northern Lights × Runtz from the Gold Line delivers up to 27 % THC with a fruity Runtz twist.
All variants share the same robust Indica base: compact growth, discreet smell, forgiving cultivation — ideal for indoor setups and discrete outdoor grows in the UK climate.
Six variants, one legend — Classic, Auto, CBD, Auto CBD and Gold Line. Direct shipping from Barcelona to the UK and worldwide.
20–22 % THC in the Northern Lights Feminized and Auto Northern Lights. The Northern Lights CBD and Auto Northern Lights CBD contain 7–12 % THC alongside 10–15 % CBD. Northern Lights × Runtz (Gold Line) reaches up to 27 % THC. The consistent Northern Lights THC content across all versions is one of the strain's most valued characteristics.
Northern Lights strain effects are primarily body-focused: fast physical relaxation, deep calm, muscle release, and at higher doses, sedation. The terpene profile — dominated by Myrcene — reinforces these effects. It's a classic end-of-day strain. Users report stress relief, pain management, and sleep support. For a lighter experience with the same NL terpenes, the Northern Lights CBD is ideal — relaxing without the intensity. Note: this is not medical advice.
Northern Lights is a near-pure Indica. Its Afghani landrace genetics give it the classic Indica structure: compact, bushy, with dense buds and short internodes. This holds across all variants — the feminized, the auto, the CBD and Auto CBD versions, and the NL × Runtz Gold Line all share that same Indica-dominant base.
Indoor: 55 days for the Northern Lights Feminized and Northern Lights CBD; 65 days for the NL × Runtz. Outdoor in the UK, harvest falls in early to mid-October under natural light. The Auto Northern Lights and Auto Northern Lights CBD are ready 70 days from germination — ideal for avoiding late autumn weather in the UK.
Up to 500 g/m² indoors for both the Northern Lights Feminized and Auto Northern Lights — exceptional for an Indica. The NL × Runtz can push further thanks to Runtz hybrid vigour. The compact Indica structure keeps all variants manageable even in small spaces.
The classic feminized version is photoperiod — it flowers only under a 12/12 light schedule and can achieve higher outdoor yields with a longer veg period. The Auto Northern Lights flowers without light control in 70 days and stays compact (up to 100 cm). THC level and effects are comparable in both (20–22 %). For UK outdoor growers, the Auto allows two harvests per season — April/May and June/July.

Yes — one of the most beginner-friendly quality strains available. Robust genetics, tolerant of environmental fluctuations, predictable growth. For a first photoperiod grow, the Northern Lights Feminized is hard to beat. For a first autoflowering grow, the Auto Northern Lights — no light management required, same legendary effect profile.
