Northern Lights Strain Feminized SeedsThe fast, compact Afghani-Thai indica, as all-female seeds
5.00 out of 5 · 4 reviewsThe Northern Lights strain is a compact, mostly indica plant (about 90% indica on Sensi Seeds' figures) descended from Afghani and Thai landraces, and one of the quickest classic photoperiods to finish. Most seed makers list 7 to 9 weeks of bloom, and Sensi quotes as little as 45 to 50 days. These feminized seeds grow female plants, so every seedling can head straight toward earthy, sweet, piney buds in a tent or a sunny garden.

What is the Northern Lights strain?
Northern Lights is a mostly indica strain, about 90% indica and 10% sativa according to Sensi Seeds, built from Afghani and Thai landrace genetics; the line was first grown in the US Pacific Northwest and reached the Netherlands in the 1980s. As a feminized photoperiod it starts flowering when the lights go to 12/12 and finishes in roughly 7 to 9 weeks. Reported THC runs from about 15% to 21%, and users most often describe a calm, heavy-bodied, sleepy effect with earthy, sweet and pine flavors.
Ratio from Sensi Seeds, which continues the Dutch Northern Lights line.
Sensi Seeds notes that Northern Lights gives off little odor during growth; its earthy, sweet aroma builds mainly at harvest and while drying.
Northern Lights strain specs
These Northern Lights figures come from Sensi Seeds, which took over The Seed Bank's line in 1991, plus Royal Queen Seeds' sheet and the SeedFinder, Leafly, AllBud and Weedmaps databases. Feminized seeds grow the same plant as the regular line; only the sex of the seeds changes, so the ranges cover both breeders' published numbers.

Where does the Northern Lights strain come from?
Northern Lights began as a group of Afghani-based indica plants grown in the US Pacific Northwest, most often placed on an island near Seattle in the late 1970s and credited to a grower remembered only as "the Indian". That part is oral history rather than documented fact. Sensi Seeds and SeedFinder describe the line as Afghani at heart with a Thai landrace in the mix, which is why Sensi rates it at about 90% indica.
Nevil Schoenmakers is reported to have brought Northern Lights to the Netherlands around 1985 and sold it through his Seed Bank, which Sensi Seeds bought in 1991. Sensi still lists Northern Lights as a Cannabis Cup gold winner and now offers it as regular, feminized and autoflowering seeds. The feminized version keeps the same plant but leaves the male seeds out of the pack.
Is Northern Lights the same as Northern Lights #5?
Not exactly: Northern Lights #5 is one numbered plant from the original Northern Lights group, while seeds sold simply as Northern Lights usually blend several of those plants. SeedFinder's family tree for Sensi's Northern Lights shows NL #1, NL #2 and NL #5. Number 5 became the famous one because breeders built hybrids such as Shiva Skunk (NL #5 × Skunk #1) and Northern Lights #5 × Haze on it.
Names vary by seed maker. Royal Queen Seeds sells it as Northern Light, without the s, and many shops shorten it to NL. Grow figures differ a little between lines, so read each seed maker's sheet on its own terms.
What does Northern Lights taste like, and how does it feel?

The order of Northern Lights' terpenes shifts between seed lines and harvests.
Reported effects
People who use Northern Lights most often describe it as relaxing and sleepy, with a heavy, full-body calm and a quiet, happy mood. SeedFinder reviewers note that a small amount feels lightly uplifting, while larger amounts can be strongly sedating.
- Relaxed
- Sleepy
- Happy
- Calm
- Hungry
Dry mouth and dry eyes are the most common Northern Lights complaints on Leafly, with occasional dizziness, and Sensi Seeds warns that the high can be strong for inexperienced users.
These Northern Lights effects summarize user reports on Leafly, AllBud, Weedmaps and SeedFinder plus the breeder's description. Everyone reacts differently, and nothing here is medical advice.
How do you grow Northern Lights seeds?
Northern Lights feminized seeds are among the easiest photoperiods to grow: veg for 3 to 5 weeks, switch the lights to 12/12, leave room for a moderate stretch, and harvest after about 7 to 9 weeks of bloom, with odor control needed mostly at the end.
- Germinate2–7 days
Northern Lights seedlings start small and delicate, so give them gentle light and water sparingly until the first true leaves open.
- Vegetate3–5 weeks indoors
A short veg is enough for a sea of green. Run 5 weeks and top once if you would rather grow fewer, bushier Northern Lights plants.
- Flower7–9 weeks
Sensi's own grow report saw more stretch than most indicas show, so keep headroom after the light change and stake the heavy main cola late in bloom.
- HarvestDay ~50–63 · late Sep–Oct outdoors
Cut when most trichomes look cloudy with a few amber heads. Expect the earthy smell to jump once the branches are hanging to dry.
Grow tips for Northern Lights
- Use the short bloom for a sea of green. Many small Northern Lights plants flipped early fill a tent quickly and finish together in about two months of flower.
- Leave room for stretch. Sensi Seeds' test plant reached 130 cm indoors, taller than its growers expected, so plan headroom or top once during veg.
- Thin the lower branches. Northern Lights grows in a Christmas-tree shape around one dominant cola; removing weak lower growth improves airflow and sends energy to the top buds.
- Fit the filter before late flower. The plant stays quiet through veg and early bloom, but finished Northern Lights buds smell rich and earthy, so have a carbon filter running before the last weeks.
- Outdoors, give it sun and heat. Sensi recommends hot, sunny summers for Northern Lights, and Royal Queen Seeds notes that its version tolerates high temperatures and forgives mistakes in veg.
- Plant only what you need. Each feminized Northern Lights seed grows a female, so you can sow exactly as many plants as your space holds without allowing extras for males.
Is Northern Lights the right strain for you?
Great pick if you
- Want a forgiving first photoperiod with a short bloom
- Prefer a calm, heavy evening indica
- Grow in a small tent and want plants that stay manageable
- Like earthy, sweet and piney flavors over candy-style ones
Think twice if you
- Want an energetic daytime sativa
- Are chasing THC figures above 25%
- Want loud fruit or dessert flavors
- Plan to breed your own crosses (regular seeds give you males)
Northern Lights strain FAQ
Is Northern Lights indica or sativa?
Northern Lights is a mostly indica strain. Sensi Seeds lists it at about 90% indica and 10% sativa, with Afghani landrace genetics doing most of the work and a smaller Thai influence. The plants stay fairly compact and users describe a relaxed, body-heavy effect.
How long does Northern Lights take to flower?
Feminized Northern Lights flowers for about 7 to 9 weeks after the lights change to 12/12. Sensi Seeds quotes 45–50 days and SeedFinder about 48 days, but other seed makers list 7–9 weeks and Sensi's own grow report ran longer, so judge by the trichomes rather than the calendar.
How much THC does Northern Lights have?
Reported Northern Lights THC runs from about 15% to 21%. SeedFinder gives 15–18%, Weedmaps 16–19% and AllBud 16–21%, and a Sensi Seeds grow report measured 20.2% in one feminized plant. CBD stays low.
How tall does Northern Lights grow?
Sensi Seeds lists Northern Lights at about 80–130 cm (2.6–4.3 ft) indoors and 150–200 cm (5–6.5 ft) outdoors. It stretches more than many indicas after the light change, so a single topping or an early flip keeps it short.
How much does Northern Lights yield?
Sensi Seeds gives about 500 g/m² indoors and around 600 g per plant outdoors for its feminized Northern Lights, and Royal Queen Seeds lists 500–550 g/m² indoors. Real harvests depend on light strength, pot size and how long you veg.
Is Northern Lights the same as Northern Lights #5?
No. Northern Lights #5 is one numbered selection from the original Northern Lights plants, best known as a parent of Shiva Skunk and Northern Lights #5 × Haze. Seed lines sold simply as Northern Lights, including Sensi's, usually combine several of the numbered plants.
Why is it called Northern Lights?
Sensi Seeds says Northern Lights is named after the aurora borealis, the colored lights seen in far northern skies. The name stayed with the line after it reached the Netherlands in the 1980s, and today it is often shortened to NL.
What is the difference between feminized and regular Northern Lights seeds?
Both grow the same Northern Lights plant. Feminized seeds produce female plants only, so every seedling can flower into buds, while regular seeds give roughly half males that need removing. Growers who want to breed with a Northern Lights male choose regular seeds instead.
When is Northern Lights ready outdoors?
Outdoors in the Northern Hemisphere, feminized Northern Lights is usually ready between late September and early October. Its quick bloom helps it finish before autumn rain in many regions, and Sensi recommends gardens with sunny, warm summers.

Mike Vee –
I’ve never smoked any cannabis quite like this one. This Northern Lights is very easy to grow; it grows to a medium size, but her goods are very large. It produces a powerful, heavy plant with lots of branches, and when I harvest it, it rewards me with a big number of buds. Additionally, this plant was quite simple to grow because it tolerates all types of climatic conditions and is fairly resistant to mold and mildew. Fantastic!
Boyd Connor –
I like how easy to grow this Northen Light, it developed a medium size yet her products are very large. This strain helped me a lot with my depression and negative thinking. I always enjoy its mind-buzz and blissful effects, her earthy, piney, and the fruity scent was really enticing.
Klaus Mikelson –
LIT! Northern Lights Fem was the coolest weed I’ve ever smoked in my life. It has the effects that sets off with a cerebral buzz that boosts my mood, simultaneously relaxes my body and mind. Growing this plant was also very easy cuz it’s pretty resistant to molds and mildews as it also withstands any kind of weather. On the medical side, it helps me cope with my anxiety and mental breakdowns.
Jerry McDonald –
Cultivated my NL fem outdoors, and it develops a robust and heavy plant with many branches and rewards me with a large number of buds on the harvest. Dried and cured her, then she emits a strong scent of earthy, herbal with a fruity hint. And after smoking, I felt a mild cerebral buzz that makes me happy at the same time.
