Northern Light Automatic

Northern Lights is one of the best-known strains of cannabis in the world. This indica cultivar derives from Afghan genetics and was originally bred in the US in the 1970s. In the 1980s, the plant made its way to Holland. Northern Light Automatic infuses the best traits of this iconic strain in a convenient, autoflowering package.

Soon after establishing itself in the Holland growing scene, Northern Lights 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 Northern Lights variants that harness the best attributes of this legend, while adding something unique to the equation. Royal Queen Seeds’ Northern Light Automatic is a perfect mix of new and old.

Being both autoflowering and feminized, Northern Light Automatic is a versatile strain that is as perfect for discreet indoor growers as it is for high-volume home-growers outdoors. After a brief vegetative phase, this strain begins producing an abundance of flowers, finishing its entire life cycle in 9–10 weeks after planting the seed.


Northern Light Automatic provides a generous harvest and might be one of the highest-yielding autoflowering strains available. 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 Automatic has 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.

Hello la team RSQ, question engraissage , je vais utiliser du all Mix et des petits champignons type MC4 ou autre. Cela va être suffisant jusqu a la floraison ? Ou dois j engraisser après sur une base raisonnable en diminuant les dose de moitié 1 semaine sur 3 ? J utilise la gamme Mastergrower d hydropassion.

Salve, volevo sapere se questa pianta sprigiona molto odore? Grazie

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:

From Paul | 2017-11-22 09:14:02

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

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.
