How to Grow Northern Lights Weed Strain
Northern Lights has graced the gardens of cannabis cultivators of every skill level. Ready to grow your own strain? Both beginners and experienced growers appreciate Northern Lights for its resilience and ease of cultivation.
Head on over to Sensi Seeds’ website to purchase feminized, regular, and autoflowering seeds. Seeds are also available at several online seed banks.
Northern Lights cannabis can be grown both indoors and outdoors, but the strain thrives in an indoor environment.
Growing indoors allows indoor growers to control environmental factors such as temperature, humidity, and light exposure, which helps maximize yield and quality. Indoors, marijuana cultivators can grow multiple times throughout the year due to its fast-growing characteristics.
This indica strain is ideal for marijuana growers who want fast results or those who want to grow weed multiple cycles throughout the year.
Many marijuana growers have had great success growing Northern Lights indoors using the SOG (sea of green) method and hydroponic or soil-based settings.
Hydroponic systems, combined with proper environmental control, can lead to higher yields and faster growth. As long as you keep an optimal airflow throughout your growth to reduce the risk of mold, you’re good.
For optimal growth, maintain the ideal temperature range of 70-80°F (21-27°C) during the day, with slightly cooler temperatures at night to mimic natural conditions and promote healthy development.
Humidity levels should be adjusted throughout the plant’s life cycle—higher during the vegetative stage and lower during the flowering stage—to prevent mold and ensure healthy growth.
Good environmental management, including proper airflow and humidity control, is essential to prevent mold and mildew.
During the vegetative stage, provide ample light exposure and maintain higher humidity to support rapid leaf and stem development. For indoor plants, maximize light exposure by using reflective materials like Mylar in your grow space.
When transitioning to the flowering stage, reduce the light cycle to 12 hours of light and 12 hours of uninterrupted darkness to trigger bud development. Maintaining consistent darkness during this period is crucial for optimal resin and bud production.
If growing outdoors, select a location with ample direct sunlight to ensure the plants receive enough light for vigorous growth and high yields.
Growing Difficulty: Easy
Plant Height: Under 30 inches
Flowering Period: 6-7 weeks
Strain Yield: 3-6 ounces per square foot
Flowering Time and Yield
One of the reasons Northern Lights is so popular among growers is its relatively short flowering time, typically ranging from 7 to 9 weeks. This quick turnaround allows for multiple harvests per year, especially when grown indoors.
When cultivated under optimal conditions, Northern Lights can yield up to 500-550 grams per square meter indoors, while outdoor growers in the Northern Hemisphere can expect up to 625 grams per plant.
The strain thrives in sunny climates with well-draining soil, making it a great option for both indoor and outdoor growers seeking high yields and potent effects.
With its reputation for reliability and productivity, Northern Lights remains one of the most popular strains for those looking to maximize their harvests.
