Northern Lights Auto Seeds: The Origins & History

Named after the aurora borealis, Northern Lights auto seeds trace back to a powerful mix of Afghani indica and Thai landrace genetics, blending deep physical relaxation with a subtle cerebral lift. The strain emerged in the late 1970s in the Pacific Northwest, where early Afghani–Thai crosses produced multiple phenotypes, with #1 and #5 standing out for potency and vigor.

In the early 1980s, breeder Nevil Schoenmakers brought these elite genetics to the Netherlands, where further refinement with Afghani males shaped the iconic indica-dominant profile known today. Its consistent performance, heavy resin production, and award-winning reputation cemented Northern Lights as a cornerstone of modern cannabis genetics.

Variations of Northern Lights cannabis seeds

When looking to buy Northern Lights seeds, choose from feminized and autoflower types in our seed collection.

Feminized Northern Lights seeds differ from regular marijuana seeds as breeders genetically modify them to produce only female plants. The crops don’t contain male chromosomes and they’re perfect for growers of all levels.

You don’t have to identify and remove the males, making cultivation fuss-free. All your crops produce delicious, smokable nugs when given the proper growing environment and care.

If you want to harvest quicker, choose autoflowering Northern Lights seeds. Unlike photoperiod strains, crops from auto Northern Lights marijuana seeds start producing buds when they mature.

Most autoflowers go from seed to harvest in about 10–12 weeks, allowing you to enjoy multiple yields. This duration may vary depending on the strain and growing conditions.

Northern Lights Seeds Characteristics

Northern Lights seeds are a longtime fan favorite thanks to their strong indica lineage, reliable performance, and well-rounded experience from grow to smoke. These seeds are incredibly forgiving, making them suitable for a wide range of growers, while still producing dense flowers, rich aroma, and a smooth, satisfying taste.

Below, we break down the defining characteristics of the Northern Lights plant, including its physical structure, terpene profile, flavor, effects, and what to expect as harvest time approaches.

What Do Northern Lights Feminized Plants Look Like?

Northern Lights seeds produce compact to medium-height plants with stout, sturdy frames inherited from their Afghani roots. Indoors, they typically stay around four feet tall. Outdoors, they can stretch a bit taller but still maintain a manageable profile.

As they enter the flowering phase, buds stack densely along the bushy branches and frost over quickly with thick, aromatic trichomes. Expect deep green hues with orange pistils woven throughout each cola.

The Terps, Taste & Scent of Northern Lights Feminized

Northern Lights strain seeds produce buds with an earthy aroma lifted by touches of citrus and pine, a signature profile shared across both the classic cultivars and many Northern Lights hybrids. As the plants mature, the scent settles into soft spice and forest herbs, and once cured, the smoke reveals a smooth, sweet flavor with hints of candy, lemon, mint, and a subtle earthy-wood taste.

Northern Lights features a terpene lineup of myrcene, caryophyllene, and limonene. These compounds shape the strain’s memorable aromatics and help define the relaxing, familiar experience people have adored for decades.

Possible Side Effects

Northern Lights is generally well-tolerated, but like most high-THC strains, it may cause mild dizziness, headaches, or couch lock if overconsumed. You might also get a little cottonmouth or dry eyes, so a drink of water and some eye drops nearby can keep things comfortable. Start with a low dose, especially if you’re sensitive to potent indica-leaning weed.

Growing Northern Lights Feminized Seeds

With strong Afghani and Thai genetics, feminized Northern Lights seeds grow into compact plants that naturally resist mold, pests, and disease. They stay low odor and adapt easily to any environment. Once settled, they reward both beginner growers and seasoned pros with excellent yields after a 6–8 week flowering period.

Indoors vs Outdoors

Northern Lights strain will grow just about anywhere, but your setup shapes everything from crop size to flavor expression. If you want maximum control and potent, year-round harvests, go for an indoor grow. If you prefer bigger crops and more sun-grown buds, outdoor cultivation is a great choice.

Growing Northern Lights Feminized Indoors:

Northern Lights grown indoors are easy to manage, usually topping out around four feet - perfect for tight spaces. Keep temps steady, give them strong light, and maintain balanced relative humidity. 

A simple SOG or ScrOG setup helps shape a full, even canopy and boosts your final yields. Indoors is where this strain really shines with THC-rich buds and deep aroma development.

Growing Northern Lights Feminized Outdoors:

When they’re growing outdoors, Northern Lights auto seeds stretch taller, often reaching six feet or more in a sunny climate. These cannabis plants love warm days, cool nights, and well-draining soil. 

Good airflow, steady hydration, and a watchful eye for early frost keep them happy. Expect outdoor plants to finish near mid-October. Give them full sun through the season, and they’ll repay you with heavy yields of sticky nugs.

The Best Grow Medium for Northern Lights Plants

Northern Lights cannabis plants perform beautifully in a range of grow mediums, but they truly shine in light, well-draining organic soil that boosts terpene expression and brings out their sweet-earthy character.

Growers who prefer more control often choose coco coir for faster development, while hydroponic setups offer the biggest yield potential and rapid vegetative growth. For best nutrient uptake, aim for a pH of 6.0–6.5 in soil or 5.5–6.0 in coco or hydro.

5 Simple Steps to Germinate Northern Lights Feminized Seeds

Before you start growing Northern Lights seeds, one of the best ways to germinate them is using the paper towel method. That’s why it’s covered in our germination guarantee. 

Here’s how to do it in five quick steps:

1. Gather what you need: two damp paper towels, a plate, purified water, and tweezers.
2. Set the cannabis seeds down on one towel and cover with the second.
3. Keep everything moist, never soaked, and avoid standing water.
4. Cover the plate and place it somewhere warm and dark.
5. Wait 1–5 days for taproots to form, then transplant gently into your medium.

For a faster start, you can pre-soak your Northern Lights cannabis seeds for 30 minutes in a mild germination solution like Homegrown Seed Spark.

How to Grow Northern Lights Weed

Growing Northern Lights seeds is as easy as it is rewarding. Thanks to their hardy landrace roots, these indica-dominant plants handle a wide range of growing conditions. Whether you’re using an indoor tent, an outdoor patch, or a greenhouse, they respond well to simple training and steady care.

Here’s a quick rundown on how to grow Northern Lights weed successfully:

1. Look After Your Northern Lights Seedlings

Northern Lights seedlings are tough little starters, but they still appreciate a gentle beginning. Start them indoors under soft, steady light and keep the soil lightly moist so their young roots can breathe. If you’re growing outdoors, let the seedlings establish a few strong nodes before moving them to your garden, ideally once nighttime temperatures stay consistently warm.

2. Guide Your Plants Through the Vegetative Phase

During the vegetative period, Northern Lights plants grow with steady vigor. Keep temperatures around 70–80°F, maintain moderate relative humidity, and give them strong light or full sun to fuel healthy growth. A gentle breeze helps strengthen stems, and once a few nodes develop, you can begin light training to open the canopy and set the stage for bigger bud sites later on.

3. Adjust Conditions During the Flowering Stage

Northern Lights’ flowering time usually runs 6–8 weeks. Indoors, switch to a 12/12 light cycle, hold temps around 70–80°F, and lower humidity to 40–50% to keep buds dense and healthy. Light defoliation improves airflow and helps lower branches catch more light. Expect sweet, earthy aromas to ramp up as resin production peaks.

4. Feed Your Northern Lights Plants Properly

Cannabis plants grown from Northern Lights seeds are generally nutrient sensitive, so start low and increase feeding gradually to avoid burn. Their feeding needs shift as they mature, so use this simple stage-by-stage guide:

• Vegetative Phase: Higher nitrogen (N) to build strong foliage and support rapid growth.
• Flowering Phase: Lower nitrogen, with increased potassium (K) and steady phosphorus (P) to develop thick, resin-rich buds.
• Late Flowering: Reduce nutrients and begin a gentle flush to enhance flavor, terpene expression, and overall bud quality.

Other nutrients like calcium, magnesium, and sulfur also step in behind the scenes, helping your plants stay sturdy, vibrant, and ready to stack flavorful buds.

5. Maximize Your Northern Lights Yield Potential

Under healthy indoor conditions, Northern Lights cannabis plants typically produce around 18 oz. (500 grams) per square meter, while outdoor crops can yield 18–21 oz. (5–600 grams) per plant in an ideal sunny climate. To push those numbers even higher, try these simple training techniques:

• Sea of Green (SOG): Grow several smaller plants closely together to create a fast, uniform canopy that maximizes light use and speeds up harvest cycles.
• Screen of Green (SCROG): Guide branches through a horizontal screen to expose more bud sites and encourage evenly sized colas across the plant.
• Early shaping and pruning: Top or gently bend stems during veg to open the canopy, then remove a few large fan leaves in early flower to help lower buds catch more light.

With its forgiving nature and natural vigor, Northern Lights is the perfect strain for simple training methods that boost its already-generous yields.

6. Prepare for Harvest & Curing

Cannabis plants grown from Northern Lights feminized seeds are ready to harvest once they complete their 6–8 week flowering period, or around mid-October outdoors, depending on your climate. In the final weeks, lower temperatures slightly to deepen the colors and boost terpene expression.

A little pre-harvest maintenance goes a long way. Remove a few large fan leaves to expose inner bud sites, keep airflow steady, and flush your medium about two weeks before harvest for a cleaner, smoother smoke. As your plants ripen, monitor trichomes carefully to dial in the exact effects you want:

Cloudy trichomes mean more balanced, classic Northern Lights effects.

More amber trichomes mean a heavier, deeply soothing finish.

Once harvested, dry your buds slowly in a cool, lightly ventilated space, then cure them in airtight jars. With a steady cure, that unmistakable Northern Lights flavor settles into its full aromatic depth, polishing your finished product into something truly special.
