Origins of the Northern Lights Strain
Northern Lights’ exact origins remain somewhat mysterious, but most agree that it was originally bred in the 1970s near Seattle, Washington, before making its way to the Netherlands in the 1980s. There, legendary breeder Neville Schoenmakers refined and stabilized the Northern Lights strain through his work at The Seed Bank, one of the first cannabis seed companies.
The Northern Lights strain’s genetics come from a mix of Afghani and Thai landraces, which explains its potent Indica effects and resilience in cultivation. Northern Lights quickly gained a reputation for its ability to deliver deep relaxation, full-body sedation, and a touch of euphoria—all with a smooth, earthy, and slightly sweet flavor profile.
Over the years, Northern Lights has become a cornerstone of cannabis breeding, contributing to iconic hybrids like Super Silver Haze and Shiva Skunk.
Best Germination Methods for the Northern Lights Strain
While there are a few ways to germinate Northern Lights seeds, some methods are more reliable than others, especially for beginners. Here are the top three germination techniques to ensure strong, healthy seedlings:
-
Paper Towel Method: One of the most popular methods, this involves placing your seeds between two damp paper towels and keeping them in a warm, dark place. Within 24–72 hours, you should see taproots emerging, signaling they’re ready for planting.
-
Direct Soil Method: For a more natural approach, plant the seeds about ½ inch deep in moist, well-draining soil. This method minimizes stress on the seedlings but requires patience, as germination can take a few extra days.
-
Water Glass Method: Some growers prefer soaking their Northern Lights seeds in a glass of lukewarm water for 12–24 hours before transferring them to soil or a paper towel. This softens the seed coat and speeds up germination.
Whichever method you choose, make sure your seeds are kept warm (around 70–85°F) and moist—but not too wet—to give them the best start.

Cultivating Northern Lights
Once your Northern Lights seeds have successfully germinated, it’s time to focus on growing a strong and healthy Northern Lights plant. Thanks to its hardy genetics, this strain is relatively easy to cultivate and adapts well to both indoor and outdoor environments.
Indoor Growing
Northern Lights thrive indoors, especially in controlled environments like grow tents or greenhouses. With its compact size and short flowering time (about 7–9 weeks), it’s a great choice for indoor growers looking for a quick and efficient harvest.
To maximize yields indoors:
-
Maintain a temperature range of 70–80°F and humidity levels around 40–50% during the vegetative stage.
-
Use high-quality LED or HID grow lights to support vigorous growth and resin production.
-
Low-Stress Training (LST) and pruning can help optimize light exposure and improve airflow.
-
Expect yields of around 16–21 oz per square meter with the right conditions.
Outdoor Growing
If you prefer growing outdoors, Northern Lights is a resilient strain that flourishes in warm, sunny climates. It does particularly well in Mediterranean-like conditions but can also thrive in more temperate regions with consistent sunlight.
For a successful outdoor grow:
-
Choose a location with plenty of direct sunlight and well-draining, nutrient-rich soil.
-
Keep an eye on humidity levels, as too much moisture can lead to mold or bud rot.
-
Outdoor plants can grow much larger than indoor ones, potentially yielding up to 22–26 oz per plant by early-to-mid October.
