What Northern Lights Is
Northern Lights is an indica-dominant cannabis strain. Lab reports put THC at 16% to 21%. CBD stays under 1%. Indoors the plant finishes in 7 to 9 weeks and stays short, from 100 cm to 150 cm. Growers list it among the easier strains to keep in a tent. The smell runs earthy, pine, and musk. The effect is body weight and quiet, not mental racing.
Lineage and History
Seed catalogs trace the strain to the Pacific Northwest in the 1970s and 1980s. Sensi Seeds describes the parentage as an Afghan indica crossed with a Thai sativa. Other accounts call it a pure Afghan line. The Dutch company sold numbered selections, NL#1 through NL#5, starting in the 1980s. NL#5 went on to parent many hybrids. Writers group Northern Lights with Skunk #1 and Haze as the three kings of modern cannabis breeding.

Cannabinoids and Terpenes
- THC: 16% to 21% in most published tests.
- CBD: below 1%.
- Myrcene: lead terpene, earthy and musky.
- Caryophyllene: pepper note.
- Pinene: pine note.
Terpene numbers move with light, feed, and cure time. Two harvests from the same mother plant can test apart by a few points.
Effects
Users report sedation, heavy limbs, and dry mouth. Appetite rises. High doses bring couch lock. The onset takes 5 to 15 minutes when smoked. Edible versions run slower, from 30 minutes to 2 hours, and last longer.
Medical Use
Patients use it for insomnia, chronic pain, and muscle spasms. Clinical trial data on this strain does not exist. Most evidence comes from surveys and patient reports. Talk to a clinician before treating a condition with cannabis.
Growing Notes
- Flowering: 7 to 9 weeks indoors.
- Outdoor harvest: late September to early October in the northern hemisphere.
- Indoor yield: about 400 to 500 g per square meter.
- Height: 100 cm to 150 cm indoors.
- Trim: dense buds hold moisture, so keep humidity below 50% in late flower.
- Training: low stress training and topping both work.
Clones keep the line stable. Seed versions vary, since the strain is not a single inbred cut.
Legal Status
Cannabis sits in Schedule I under US federal law. State rules range from full adult use to felony bans. Check state law before buying, growing, or moving plants across lines.
