STRNG Seeds – Northern Lights Auto

Northern Lights Autoflower is known for its fast growth, ease of cultivation, and deeply relaxing experiences. It combines the original Northern Lights genetics with ruderalis to allow for automatic flowering, making it ideal for growers seeking simplicity and speed.

Northern Lights Auto is predominantly indica, often with over 80% indica genetics. This results in soothing body experiences, stress relief, and a tranquil, experience perfect for evening use.

It’s low-maintenance, compact, and highly resilient — ideal for those new to growing. Even with minimal intervention, Northern Lights Auto consistently produces dense, frosty buds in under 10 weeks.

Its forgiving nature, short cycle, and reliable bud quality make it a smart choice for dialing in a new grow space or testing a new setup.

Northern Lights Auto offers an earthy, pine-forward aroma with subtle sweet and herbal undertones. The flavor mirrors this profile with added notes of spice and citrus during exhale.

Northern Lights Auto typically completes its entire life cycle in just 9–10 weeks from seed. This rapid growth makes it perfect for multiple harvests per season or quick indoor rotations.

Indoor growers can expect around 400–500g/m², while outdoor plants may yield 100–200g per plant. Its compact size and fast flowering do not sacrifice bud quality.

A 3-gallon (11-liter) pot is usually sufficient, though some growers prefer 5 gallons for maximum root space. Autoflowers don’t need massive containers due to their compact size.

Absolutely. It thrives in both settings. Indoors, its compact form suits small grow tents, while outdoors it performs well even in cooler climates due to its short life cycle.

STRNG Seeds offers premium Northern Lights Autoflower genetics with a proven reputation for stability, high germination rates, and consistent results. Whether you’re a first-time grower or an experienced cultivator, our seed ensures quality, reliability, and fast, discreet delivery.

The main difference is that Northern Lights Auto flowers automatically based on age, not light cycles. While both offer the same soothing experiences and aroma, the autoflower version is faster and more beginner-friendly.

Autoflower strains like Northern Lights Auto transition to the flowering phase automatically after a set time, usually 3–4 weeks, regardless of light exposure. This trait comes from crossing traditional strains with ruderalis.

No, they don’t rely on the 12/12 light cycle that photoperiod strains need. Most growers use 18/6 or even 20/4 schedules from start to finish for optimal growth.

While you can use low-stress training (LST), topping or aggressive high-stress training is generally discouraged due to the short veg period. Gentle bending or tying is preferred to maximize light exposure.

Autoflowers are more sensitive to overfeeding. It’s recommended to start with half-strength nutrients and adjust based on how the plant responds, especially in early stages.

A light, well-aerated soil mix with good drainage is ideal — often with added perlite or coco coir. Autoflowers benefit from low-nutrient starter soils to avoid seedling burn.

It’s best to avoid transplanting autoflowers due to their short veg cycle. Starting them in their final pot (3–5 gallons) helps avoid stress that could stunt growth.

Look for milky-white trichomes with some turning amber. Pistils should be mostly orange or brown. Most autoflowers, including Northern Lights, are ready around week 9 or 10 from sprout.

In warmer regions, yes. Autoflowers can be grown multiple times per season since they aren’t tied to changing light hours. Just make sure temperatures stay above 15°C (60°F).

Not necessarily. While some autoflowers are bred for discretion, most still produce a strong aroma during flowering. Carbon filters or outdoor spacing can help manage smell.
