• Yield: 400–500g/m² (indoor), 50–200g per plant (outdoor)

• Aroma and Flavor: Earthy with sweet and spicy notes

• Cultivation Notes: Northern Lights is a classic strain favored for its resilience and ease of growth. Its short flowering time and generous yields make it a staple for indoor growers seeking reliable results.

Growth Characteristics: 10/10

Northern Lights Autoflower gets a 10 out of 10 regarding growth characteristics because of its short flowering time, resilience, and durability. This seed is ideal for new growers because it can flourish in all environments and is resilient to human error and miscalculations of lighting, watering, and feeding. It almost always yields an insane amount of bud.

Seed Genetics: 10/10

Northern Lights has a genetic background in Afghan and Thai landrace strains. Afghan Landrace contains pure Indica genetics contributing to the Northern Lights' compact structure, fast flowering time, and heavy resin production. Afghan strains are known for their hardiness, profound relaxation effects, and resistance to pests and mold. 

The Sativa influence from Thai landraces adds a subtle cerebral uplift, preventing Northern Lights from being a complete “in-da-couch” strain. Thai strains also enhance the flavor profile, introducing hints of spice and sweetness to its earthy aroma.

By crossing these legendary landraces, breeders created Northern Lights, one of the most stable, potent, and easy-to-grow Indica-dominant hybrids, ideal for beginners and experienced growers.

Effects & Potency: 9.75/10

People love Northern Lights for its calming effects that relieve stress, relax muscles, and induce sleep. With a moderate potency between 20% and 25% THC, Northern Lights is ideal for regular evening use for both beginner and veteran smokers; however, smoking in large quantities can make you feel sleepy quite quickly.  

When smoked moderately, the Sativa side of this hybrid is more recognized for its cerebral uplift and soothing mental state.

Aroma & Flavor Profile: 10/10

Northern Lights is super dank and skunky, with a sweet, earthy scent and hints of pepper and spices. This gives it a similar quality to incense sticks used for meditation or cleansing your living space. 

The flavor has been described as mildly sweet on the inhale with an almost honey-like taste, followed by an exhale dominated by fresh pine and earthiness. Some variations are also known to carry a lingering lemon zest or peppery flavor. 

Total Score: 9.84/10

Why They Stand Out

Northern Lights Autoflower by Seed Supreme stands out because of its outstanding growth characteristics, resilience, and how easy it is to grow, making it the ideal choice for beginner growers. Its elite genetics, derived from Afghan and Thai landrace strains, contribute to its compact structure, fast flowering time, and high resin production while balancing its relaxing indica effects with a subtle cerebral uplift. 

With a moderate yet potent THC content (20-25%), it delivers deep relaxation, stress relief, and a mildly uplifting mental state, making it great for evening use. Additionally, its distinct aroma and flavor profile, featuring earthy, sweet, and spicy notes, further enhance its appeal, earning it an overall rating of 9.84/10.

Why Choose Autoflower Seeds?

Many people choose autoflower seeds every day, whether they are beginners or master gardeners. Using autoflower seeds is not considered cheating, no matter what your hipster friends try to tell you. 

The only real downside of using autoflower seeds is you may get a slightly lower yield and potency, and you cannot use high-stress training techniques or clone your plants, but for the average home grower, the benefits far outweigh the drawbacks. 

Benefits of Autoflower Seeds

This is why thousands of home growers, including experts, choose autoflower seeds over regular seeds. 

• No light cycle adjustments needed: Autoflowers transition to flowering automatically and do not require you to adjust the lighting exposure times as the seed transitions from the seedling to vegetative to the flowering and late-flowering stages. This makes them much easier to grow. Simply ensure they have a minimum of four hours of direct sunlight, and they will grow. 

• Quicker flowering time: Autoflowering seeds flower much faster than regular (photoperiod) seeds, typically completing their entire life cycle in 8-10 weeks, while regular seeds take 3-6 months. For people looking to start saving money on growing their own buds, the convenience factor of the quicker flowering time is hard to ignore. 

• Beginner-friendly: Autoflower seeds require much less maintenance and are more forgiving of lighting, watering, and feeding mistakes that beginners can easily make. They are the rotisserie oven of the growing world—just set them and forget them. 

• Resilient to environmental stress: Whether grown indoors or outdoors, in warm or cool climates, with abundant sunlight light or in the shade, in nutrient-dense soil or drier dirt, autoflower seeds are likely to produce some sort of yield. It is tough to mess up growing with autoflower seeds.

• Compact and discreet: Autoflower seeds typically produce smaller plant sizes that are bushy and compact, making them perfect for indoor grows using grow tents or closet setups and stealthy outdoor cultivation. 

• Consistent and sizeable yields: Autoflower seeds produce solid harvests with thick, high-quality buds despite smaller plant sizes. 

Again, for many home growers looking for a solid yield of their favorite strain of weed for a much lower price than what they pay at their local dispensary, autoflower seeds are well worth the time and effort. 

How to Grow Autoflower Seeds

People love growing with autoflower seeds because it is relatively simple. To start, plant your seeds in light, aerated soil with good drainage to support root development. Since autoflower seeds grow more rapidly, it is better to start off using a larger pot, like a 3 to 5-gallon bucket, so you don’t need to transplant the plant later and shock it unnecessarily.

Autoflower seeds flourish best with 18 to 24 hours of lighting, although it is not required. These seeds can grow with as little as four hours of sunlight daily coming in from your basement or living room window. Additionally, autoflower seeds do not rely on darkness to trigger flowering; however, many growers have found that 20 hours on and four hours off produce the best results compared to 24-hour light.

Regarding watering, avoid overwatering, as their smaller root systems tend to be more sensitive to excessive moisture. If precautions are not taken, Bud rot, mold, and mildew can become an issue. Additionally, never use high-stress training techniques like topping, as auto flowers have a shorter vegetative stage. Instead, opt for low-stress training techniques that are better suited for the shorter life cycle. 

Differences from Regular (Photoperiod) Seeds

The most significant difference between autoflow and regular seeds is when and how they transition to the flowering phases. Autoflower seeds begin to flower automatically after three to five weeks, regardless of the light cycle. In contrast, regular seeds require a change in lighting throughout the various phases of the growth cycle, especially to trigger flowering. 

This means that growers don’t need to worry so much about adjusting light schedules, making it more convenient for everyone and more straightforward for new growers. 

Lastly, autoflower plants tend to be smaller than photoperiod plants, making them ideal for indoor growing or places where space is limited or discretion is required. 

Considerations for Autoflower Growing 

The main thing to remember when using autoflower seeds is that they grow much faster than regular seeds. Because of this, autoflower plants have a shorter vegetative phase and less time to recover from stress induced by overfeeding or overwatering. 

However, since autoflower plants are more resilient and forgiving, you don’t need to worry too much about it; just optimize your process from the start and make adjustments as soon as you notice symptoms occurring from over or under-watering or improper feeding amounts. 

Overall, autoflower seeds are perfect for growers seeking a quick and hassle-free harvest with minimal intervention. 

FAQs on the Best Autoflower Seeds

1. What are autoflower seeds, and how do they differ from regular seeds?

Yes! Autoflowers are easy to grow, require minimal maintenance, and don’t need strict light schedules. Their fast life cycle means less waiting but also less time to fix mistakes. With proper care, they’re an excellent choice for first-time growers looking for a quick and hassle-free harvest.
