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 five 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 five 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 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.

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.

Northern Lights CBD carries the full terpene profile of the original — earthy sweetness, pine resin, spice — at 10–15 % CBD and 7–12 % THC. Photoperiod and feminized, with the same stable, forgiving NL genetics. 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.

Frequently Asked Questions about Northern Lights
What is the THC level of Northern Lights?
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.
What are the effects of Northern Lights?
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.
Is Northern Lights indica or sativa?
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.
What is the flowering time for Northern Lights?
Indoor: 55 days for the Northern Lights Feminized and Northern Lights CBD; 65 days for the NL × Runtz. Outdoor in the UK, harvest falls late September to early 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.
What is the yield of Northern Lights?
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.
What is the difference between Northern Lights and Northern Lights Automatic?
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.
Where can I buy Northern Lights seeds in the UK?
Pyramid Seeds ships directly from Barcelona with discreet worldwide delivery. The full collection — feminized, autoflowering, CBD, Auto CBD, and Gold Line — is at the Northern Lights collection.
Is Northern Lights good for beginners?
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.
