Best Northern Lights Strain: Comparison and Picks
Lab results
Cannabis labs report THC in two forms: THCA and delta-9 THC. THCA turns into THC when heated. Total THC combines both. For Northern Lights, total THC lands in the 16% to 21% window. A 2021 survey of dispensary menus in the US found an average of 18.7% for Northern Lights flower. That number shifts by batch.
What changes the THC number
Grower, light, and harvest time move the percentage.
- Indoor grows under LED or HPS lights produce 18% to 22% THC.
- Outdoor grows in climates with short seasons produce 12% to 16%.
- Harvest at trichome maturity raises THC. Harvest after trichomes turn amber lowers it.
- Curing time of 2 to 4 weeks protects cannabinoid levels.
CBD and other cannabinoids
Northern Lights carries CBD at 0.1% to 0.3%. CBG appears at 0.1% to 0.5%. CBC and CBN show at trace levels. CBD below 1% means the strain does not balance THC with another cannabinoid. That fact shapes the effect profile.
Effects tied to THC percentage
A 16% sample gives a body high. A 21% sample gives a sedative effect. Users with no tolerance report racing thoughts at 20% and above. Tolerance changes the result. That percentage can feel different from person to person.
Testing and labels
State rules require THC labels on cannabis sold in licensed shops. Those labels show total THC. A label of 18% means 18 mg of THC per 100 mg of flower. That equals 180 mg per gram. Check the batch date. THC drops as flower ages. A 6-month-old sample can lose 10% to 20% of its THC.
