The History of Northern Lights

If Haze is the ancestor of modern sativas, Northern Lights is the ancestor of almost everything else. It is probably the most widely used indica parent in the history of commercial cannabis breeding, and, as with Haze, its documented history is thinner than its reputation.

The method here is simple: documented fact, plausible reconstruction and marketing are kept apart, and anecdote is labelled as anecdote.

The account, as it is usually told

Northern Lights is said to have been created in the 1970s, on an island near Seattle, Washington, by a breeder known only by a nickname, usually recorded as “the Indian”. Some accounts place the material in California before he began working with it. Sensi Seeds tells a different version: in its account the line was stabilised in the Pacific Northwest by a group of breeders it calls the “Northern Lights Crew”.

The account holds that there were eleven plants, labelled NL#1 through NL#11, and that they were originally pure Afghani: resinous, compact, dark green and stable.

Of the eleven:

  • NL#1: described as a true-breeding Afghani inbred line
  • NL#2: described as a potent NL#1 × Hindu Kush hybrid
  • NL#5: regarded as the best of the group and, according to Alchimia, probably the only one of the original females kept pure

Northern Lights reached the Netherlands c. 1984–85 through Nevil Schoenmakers and his Seed Bank. Alchimia gives 1985; other accounts place Schoenmakers’ acquisition in the early 1980s. Almost everything sold under the name descends from what Schoenmakers, and later Sensi Seeds, did with that material.

The gap in the story that nobody has closed

There is a specific problem with the standard account, and to their credit the better sources raise it themselves rather than glossing over it.

The plants given to Nevil are described as all female. If that is accurate, there were no Northern Lights males in the Netherlands, and nobody has explained where the seed came from.

The usual explanation is that Schoenmakers used Afghani males of his own for hybridisation and inbreeding, building a seed line around the females. That is plausible, but it is not documented. If it is true, it has a consequence that matters: commercial “Northern Lights” seed from the mid-1980s onwards is not the original plant. It is a reconstruction of that plant around a different male, and the pure-Afghani claim applies to the original females, not to the seed anyone has actually bought since.

Sensi Seeds’ own company history complicates this further. It quotes a recollection that one of the original breeders arrived “with a whole heap of seeds that were labelled with a whole heap of numbers”. The two versions cannot both be complete, and neither is documented.

Alchimia itself presents the Afghani-male explanation as the most likely theory rather than as fact, and this post will not do better than that.

A conflict worth flagging

Some older regional sources suggest that Northern Lights has Thai sativa ancestry. The main accounts say the Thai genes were added later, through hybrids.

Alchimia’s version is definite: the original eleven plants were pure Afghani, and Thai sativa genes were introduced later into some of the hybrids, not into the original line. The obvious example is the NL#5 × Haze family, where Thai landrace ancestry does come in through Haze.

Sensi Seeds, which bought The Seed Bank in 1991, does not fit neatly into either camp. Its catalogue page says Afghani and Thai genetics were added to the line after it reached the Netherlands, while its company history calls the original an Afghan × Thai hybrid.

These accounts cannot all be right, and without genetic data the question cannot be settled. We are recording the conflict rather than picking a side.

What Northern Lights actually is, horticulturally

Leaving the history aside, here is why breeders turned to it so consistently:

Very high resin production, with dense flowers.

Short flowering time: around two months or a little less. Sensi Seeds lists 45–50 days. For a heavy-yielding line, this was the property that decided its commercial success.

Bushy structure with many strong side branches. It suits a screen, topping and a limited canopy.

Mould: the descriptions disagree. Some seller and grower descriptions call Northern Lights fairly hardy, even mould-resistant. Alchimia warns that its compact buds can develop mould during flowering, especially in humid climates. Neither label should be read as a fixed trait.

What is not in dispute is how dense flowers behave. Tight, heavy buds hold moisture in the interior, where airflow does not reach. Botrytis (bud rot) starts in exactly those conditions, and by the time it is visible from outside it is already established inside.

For growers in Southeast Asia, this is the most important point, and it applies to dense-flowered lines in general, not only to Northern Lights. A Thai wet season brings 80%+ humidity for weeks at a time, and in those conditions dense indica flowers carry a real Botrytis risk whatever the breeder’s label says. Any dense-flowered genetics here need dehumidification, real airflow through the canopy rather than over it, and a willingness to harvest early rather than lose the crop. Forum topics #1245 and #28 cover this in more detail.

Aroma, as described in the older literature: mild rather than pungent, with pine, earth and a honeyed sweetness. It is noticeably less sharp than classic Afghani lines such as Afghani #1. The high resin content is why hash makers historically valued it.

The hybrids

Northern Lights’ influence is easier to see as a list than as a claim.

Direct versions: Sensi Seeds sells the line as Northern Lights, and Alchimia identifies Sensi’s version as the original NL#1. Alchimia also lists NL-based hybrids from Female Seeds, Pyramid Seeds, Genehtik and Royal Queen Seeds. Several other named derivatives that circulate online are left out here because we could not confirm the Northern Lights pedigree on the breeders’ own pages.

The most influential hybrids:

  • NL#5 × Haze: the indica × sativa F1 most closely associated with Schoenmakers, and among the most successful Cup entries of the late 1980s and early 1990s. Sensi Seeds’ company history reports that it took first place in the Mostly Sativa category for The Seed Bank at the 1990 Cup, and won again in 1993 for The Sensi Seed Bank.
  • NL#5 × Skunk#1, also called Shiva Skunk: easy to grow, heavy and resinous. A workhorse.
  • Jack Herer carries NL#5 in its pedigree.
  • Super Silver Haze and Neville’s Haze both trace back through NL#5.
  • NL5/Afghan (Mr Nice), and a long list of others.

Put this list next to the Haze family and a pattern appears. Many of the landmark cultivars of the 1990s are Northern Lights × Haze recombinations in some proportion. To a considerable extent, the commercial cannabis gene pool of that decade was two lines crossed against each other, and against Skunk material, in different ratios.

Why the reputation outran the documentation

Northern Lights arrived just as a market appeared. Schoenmakers set up The Seed Bank c. 1984–85 (one account says 1983) and is described as the first seed company to advertise directly to the public in High Times. Northern Lights reached him c. 1984–85. The first High Times Cannabis Cup is generally dated to 1987, although some accounts treat the 1988 Amsterdam event as the first official Cup. So a line that yielded heavily, finished fast and was rich in resin ended up with one of the first breeders selling seed by mail order to an international audience.

That is a commercial history as much as a genetic one, and it is worth keeping in view. Northern Lights is not necessarily the best indica anyone ever bred. It is the best indica that was in the right place when distribution was invented.

A note on the evidence

Every specific claim in this post rests on secondary accounts written decades after the events, by people who were not there, drawing on statements by people who had reasons to shape the story. That includes the island near Seattle, the eleven numbered plants, the nickname and the pure-Afghani origin.

There are no primary documents and no contemporaneous records. We are not aware of published genomic work testing these specific pedigree claims, although the tools to do it have existed for years.

Treat the horticultural description as reliable: it is testable, and thousands of growers have tested it. Treat the origin story as folklore that is probably broadly true.

This article is historical and educational. In Thailand, growing cannabis requires the relevant permits. Cannabis flower is a controlled herb under the Notification of the Ministry of Public Health Re: Controlled Herbs (Cannabis) B.E. 2568. It may be dispensed only against a prescription on form PT 33 from an authorised practitioner, and it may not be advertised or sold online. The Cannabis Control Act is still a draft: the Cabinet approved it on 22 September 2026 and sent it to the House. For the legal background, see forum topics #1330 and #136.
