Northern Light Auto Seeds: An American Strain Improved Over the Years

Soon after establishing itself in the Holland growing scene, Northern Lights cannabis seeds became the standard for indoor cannabis cultivation. Its influence spread worldwide as it went on to become one of the foundations of modern cannabis breeding. In recent years, different growing and breeding techniques have resulted in variants of the Northern Lights cannabis strain, with each harnessing the best attributes of this legend, while adding something unique to the equation. Royal Queen Seeds’ Northern Light Auto seeds are the perfect mix of new and old.

Being both autoflowering and feminized, Northern Light Auto seeds are versatile enough to suit discreet indoor grow ops or high-volume outdoor growers. After a brief vegetative phase, this strain begins producing an abundance of flowers, finishing its entire life cycle in 10–12 weeks after planting the seed.

Insane Yields From the Northern Light Auto Strain

The Northern Light Auto strain provides a generous harvest and might be one of the highest-yielding autoflowering seeds available today. Growing to a height of around 90–120cm, it is quite a large plant for an auto, which explains its yields of up to 200g/plant outdoors and a whopping 550g/m² indoors.

Much like the original Northern Lights, our Northern Light Auto strain offers a nice, sweet taste and a comfortable physical effect accompanied by cerebral stimulation. It’s the same classic strain, just with an autoflowering twist—which also makes it a great strain for medical users.

    Comment : Great strain for beginners. Very easy to grow, handled the outdoor weather really well and grew fast with minimal maintenance. Nice compact plant with a good yield and smooth smoke. Definitely recommend Northern Lights Auto if you’re new to growing or want something low effort.

    Comment : All seeds are super strong and fast 9/9 nothing fail great seed I am so happy can’t wait to order to collect more seed autoflowering

    By C. K. on 05/Feb/2026 :

    Comment : Great strain does good buds alil earlier than what says but that just let's buds develop more

    By C. S. on 26/Jan/2026 :

    Comment : Grew about 4ft outdoors and the tops were single colas bigger than my arm. Good Stuff!!

    By J. J. on 23/Jan/2026 :

    Comment : This was one of my first strains I grew. Was a pretty healthy plant, but my brother thought it was a photo period and told me to top it. I topped it, but a week later realized it triggers it into flower. It got a decent amount of tri's and smelled good out of cure, but unfortunately didn't give me much of a buzz and only procedure 1 OZ of bud. Helped me with some of my back pain though.

    By K. L. on 24/Nov/2025 :

    Comment : This is a great strain she grew over 5 feet & when I tell you she took off to the races I’ll definitely recommend this strain

    By C. M. on 19/Nov/2025 :

    Comment : Only got about 4 ozs but who cares when its personal use. I will keep buying these no matter what. Very quick and easy

    By R. R. on 16/Nov/2025 :

    Comment : I planted all three free seeds and surprisingly they grew pretty big along side the other one I purchased.

    By A. O. on 05/Nov/2025 :

    Comment : Planted 2 seeds to try out 2 different pot sizes. A 5 gal vs the 3 gal. only really difference so far is 3 gal is not as bushy. the branches are shorter but it doesnt look like is has effected the bud development. They are both heavy plants. way over what I was expecting. At first is was skeptical. the seeds didn't look that great. but I had room and wanted something different. Im extremely happy with how they have turned out. Im in week 14 from seed of the plant and they started the last growth cycle in bloom. kicking out there last foxtails. right now I'm just waiting out the terps to start ambering to call them finished. Im excited to see how these finish up.

    By M. Z. on 01/Nov/2025 :

    Comment : All seeds germinated however they were very small and scraggly, I’ve had much better luck with the photoperiod seeds

    By M. B. on 15/Oct/2025 :

    Comment : Alles Top, Gut gekeimt sowie problemlose Wachstums und Blütephase. Insgesamt war es echt ein entspannter Grow. Zum Geschmack kann ich noch nicht viel sagen ist noch am Trocknen stinkt aber schonmal gewaltig. Nach einer gesamt Zeit von ca. 10,5 Wochen geerntet und schätze das sie gute 100g bringen wird trocken bei einer Größe von ca. 70- 80 cm. Werde sie öfter mal nebenbei im Zelt mitlaufen lassen. Fazit: Guter Ertrag und absolut pflegeleicht, immer wieder gern.

Can north ligths auto and the thunder fuck grow outdoors in the uk

Royal Queen Seeds Team

Yes, both Northern Lights Auto and Thunderfuck can grow outdoors in the UK, as they are well-suited to a variety of climates. However, since the UK climate can be unpredictable, it’s important to start your plants early in the growing season to maximize the amount of sunlight they receive. Autoflowering strains like Northern Lights Auto are especially resilient and can handle the shorter growing seasons. Just ensure they get plenty of light, warmth, and protection from extreme weather.

Royal Queen Seeds Team

It is very hard to provide you with an accurate answer. It is not only about light and space, it is also about feeding, watering, ventilation, etc...

what thc level is northern light

Royal Queen Seeds Team

You can check this information in the data sheet of each product. Northern Light 14%

From erik | 2017-10-17 19:39:27

hola buenas me gustaria saber si es posible sembrar una northen light en invierno con 10 horas de luz y enfrente del mar para hacer en outdoor

Royal Queen Seeds Team

Es posible pero los resultados estarán siempre muy por debajo de las expectativas, en caso de que la planta crezca en condiciones. Nosotros no recomendamos exponer las plantas a temperaturas por debajo de los 12ºC, ni con un intervalos de más de 10ºC entre máxima y mínima. Además con tan pocas horas de luz la planta no crecerá demasiado.
