An American Strain improved with the years

Northern Light is one of the best-known strains of cannabis in the world. It’s a mostly Indica strain bred in the 1970s in the USA from Afghani genetics. In the 1980s, the plant came to Holland. It soon become the standard for indoor growing. Over the last few years, there have been many changes in growing and breeding techniques. Our Northern Light Automatic is a perfect mix of new and old.

Now this strain is both autoflowering and feminized. Northern Light Automatic is great for growing indoors but can also been grown outdoors in most climates. The plant starts growing and producing flowers almost immediately, and is ready for harvest in only 9 to 10 weeks from planting the seeds.

One of the Auto strains with highest yield 

Northern Light Automatic gives a generous harvest and might be one of the highest-yielding autoflowering strains available. Growing to a height of around 90-120 cm, it is quite a large plant for an autoflowering variety, but this is matched in its yield. Outdoors in Spain some plants have produced upto 200 g, although  the average indoors yield in good conditions is around 90 g.

Much like the original Northern Lights, our Northern Lights Automatic has a nice, sweet taste and a comfortable physical effect. It’s the same classic strain, just with an autoflowering twist. Which also makes it a great plant for medical users.

    Title : Amazing strain
    Comment : I have planted this strain last summer, it did so well. I used 25L pot in coco soil with biobizz nutrients with natural sunlight and was able to get about 100 grams per plant. Its awesome for an automatic plant. Really easy and result is amazing. Good taste and also a powerfull indica. Just bough more seeds 2 days ago. Gonna repeat it again.

    Title : The Northern Legend
    Comment : A beautiful plant. For an autoflower she becomes rather tall with dark leaves. Lovely taste (as do have many of Royal Queen Seeds) and big buds. She takes a few weeks more then other auto's but she is well worth it. One my favorites. The Old Legendary Northern Light!

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

Under data sheet it says: Flowering: 5-7 weeks Does this mean that the flowering stage starts after week 5-7, or does it mean that the flowering stage takes 5-7 weeks?

Royal Queen Seeds Team

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

Bonjour RQS Combien puis je récolter avec cette auto ? En Indoor placard de 1,70m.70.70 éclairage Led panneaux 1000W double spectre !? Merci.

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.
