The Northern Lights was developed in the 70's. This makes the Northern Lights one of the world's oldest and most well-known cannabis varieties. In the 80’s, Northern Lights came via the USA to the Netherlands where the strain is further optimized. Here the plant was crossed with a ruderalis to add automatic flowering genes to the plant. With an amazing result. Together with Big Bud x Northern Lights and the Big Amnesia autoflower, our Northern Lights autoflowering feminized seeds are now one of the most productive autoflowers available.

Northern Lights autoflower seeds

Our Northern Lights automatic is both an autoflowering and feminized variety. Which means the plant will bloom automatically and produce flowers without the change of a light regime. The strains love indoor- as well as outdoor environments. The perfect choice for the experienced ones and beginners. 

Northern lights autoflower flowering time

During the cycle this plant with an average mold resistance develops an abundance of robust thick, dense and beautiful buds. The Northern Lights autoflower seeds need a flowering period of 9-10 weeks to grow into an adult cannabis plant which means that the total cycle is about 11-13 weeks. 


Of course the pot size is important when it comes to the plant height but on average the plant will reach a height of 70 cm - 120 cm when grown indoors. Outdoors in the open ground the plant can even reach a height of 170 cm. With these plant sizes it isn't strange that the yields can be very rewarding. Growers reported that they yielded up to 200 grams per plant and with methods like Sea of ​​Green (the SOG method) yields even rose up to 600 grams per m2. For an autoflower variety, these returns are truly amazing.

Taste, smell and effect

Northern Lights autoflower weed has exactly the same taste, smell and effect as the non-autoflowering variation. A wonderful pleasant, sweet taste combined with a comfortable, physical effect and a happy, relaxed feeling in both the body and mind. Due to it's mainly Indica properties to strain is amazing to relax with.

Bought some of these seeds as well as some granddaddy purple and godfather OG. Planted 2 seeds of each and everything has came up nicely! and about four weeks after planting the seeds they all have nice 5 to 7 prong leaves. A couple more weeks in veg and I’ll move all these ladies to flower for about 8 weeks. Total Cicle about 14 weeks from putting the seed in soil to harvest.

Just want to say thank you muchly for the amazing service and delivery, which was just amazing. Out of the 5 I ordered( plus the extra one for free, Thanks again) I had 4 come up strong and impressive early growth. The other 2 failed but many things could’ve caused this with this far a journey. I have no problem with the remaining 4 which are now all flowering nicely and happy recommend you to freinds.

Just a classic one! Great yields, easy growing, love this strain man and the great genetics from weedseedsexpress. Thank you for everything!

I have had bad weather outside and unfortunately lost 1 plant, but I have been able to harvest the other 4 plants with great success so if you are looking for a reliable strain that is capable of achieving good harvests under all circumstances, I can certainly recommend this strain.

J. Vasquez (verified customer) 2018-11-22

There's nothing like a well-kept Northern Light bud and it was an honor to grow this strain. The shape of the buds is great. Rich with THC crystals, dense and thick. Moreover, the plant was easy to grow. As soon as your weed is dry and you smoke this lady, the adventure really starts. The full taste is characterized by the fruity aspect. The effects may have a different effect on everyone, but I became quite active.

Kelley (verified customer) 2018-09-04

Northern light has been one of my favorite cannabis varieties for years. Not only because of the fine taste, but also because of the ease to grow and the yields. Maybe I think this autoflower is a better variant than the non-auto

Marez (verified customer) 2018-04-23

I found this plant very easy to grow. Besides it did exactly what the description says.

M. Hunter (verified customer) 2017-08-05

After a few scams I am glad I bought seeds from weed seeds express. Everything went smoothly. From payment to delivery and germination. Thank you very much. I recommend you guys to everyone

Nathan Perez (verified customer) 2017-01-14

Normally im not an Indica fan. However, this strain made me think about by opinion again. Really easy to grow strain and big big biiiggg yields. The effect is just as amazing as the strain itself. Sweet taste and the high thc content blow my mind. My body felt happy and relaxed.
