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 in the autoflower 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.

    Title : Not My Favorite
    Comment : Not hating on the plant at all, grew wonderfully just a tad bit hungry for nutrients which I waited too long to do anything about. Still grew to almost 19" and yielded 47g after dry and trim. Just not a fan of the strain itself, the smell profile is not for me and the smoke is definitely not what I'm looking for.

    Title : Killer freebies
    Comment : These and their photos have grown exceptionally good indica style nugs every time I have grown them. I bought the photo based on how much I liked the auto. Very simple straight forward, resilient plant for beginners too, as I topped, transplanted and lsted with no issue at all. 75 -80days after sprout. really easy trim, too. Nothing compared to that smooth ass smoke that brought me back to high school, sweet emotion style. thanks rqs. M3RC.

    Title : Very Nice Grow
    Comment : This is in my top 3 of the best grows I have ever done. (Blue Cheese and Grandaddy Purple the others) I used red bag Promix, Growdots and recharge, that's it. Got a little over 3 oz of very good smoke and this plant was a true pleasure to grow, a lot of fun to watch it get bigger every day.

    Title : First Grow Interesting Variability
    Comment : My first grow! I'm so glad I went with RQS Northern Light Autoflower seeds. I grew two side-by-side, and it amazed me how they grew at different rates. They were both wonderful plants to grow, one staying more compact while still producing beautiful buds all over the place. I didn't train either of them because I like to let nature do its thing. The other plant grew larger and taller, with a bit of a stalkier appearance, so it could have used a little training. They are both still producing, though the smaller plant does appear to be a little ahead in terms of flowering. I'm excited to see how the flower turns out, as both plants are already starting to produce some beautiful buds.

    Title : Impressive Survivor, Great High
    Comment : Poor girl survived every mistake one could possibly make on a first grow, including terrible weather, insufficient light, wind, over-pruning. No nutes, either, just planted in living soil. I couldn't believe she survived and actually gave me something (though it wasn't much, of course). The flowering scent was a light, pine-citrus. The high is both uplifting and relaxing (great for those of us who are high-anxiety, especially post-election), the flavor delicious (also pine-citrus). I will definitely grow this strain again and be much much nicer to her.

    Title : North Lights Auto
    Comment : So I grew 2 of these autos in a 4x4 under a 400w light and boy was I glad I only put in 2 plants...they got HUGE. both measured out around 4ft and bushy. They were completely different phenos, 1 was bushier with huge colas (90ish gs wet, still drying) other lankier with smaller buds. Smelled completely different, both great. Pulled around 5oz of dried flower off number 1, 2nd is still drying. One 1 cut at around 85ish days and other went over 100 days. Thwy were great plants, smell great and get me high for sure

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 depends, if plants are healthy and happy their smell intensity is increasing as they get closer to the harvest time. However there are some techniques to camouflage the smell, check out the below link: https://www.royalqueenseeds.com/blog-how-to-control-the-smell-of-cannabis-n224

It means that the blooming period takes between 5 and 7 weeks.

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.
