Growing Northern Lights Auto (indoors and outdoors)

Our Northern Light automatic is both an autoflowering and feminized strain and a perfect choice for both discrete indoor and outdoor growers. The total life cycle of the seeds takes 11 to 13 weeks to grow into a mature weed plant with medium resistance to fungus.

Indoor vs. outdoor

The Northern Lights Autoflower lends itself best to indoor growing. This is because the strain is somewhat sensitive to fungi, but also because the plant grows in height and gives a lot of yield per plant. So you do not need a lot of indoor space.

Do you want to grow indoors or outdoors? You can do both. Northern Lights Autoflower is suitable for growing indoors, but has also proven to be able to grow outside in a sunny Mediterranean climate and even a temperate climate. Do you want to increase the success of outdoor growing? Take a look at our blog 'growing weed outdoors'.

Flowering time

During the relatively short flowering period, the plant develops an abundance of robust full buds. This is also one of the properties for which the Northern Lights is known: a high yield without taking up a lot of space. And in a short time. Of course, it does matter whether you grow indoors or outdoors. Under ideal weather conditions, the plant will give a higher yield outdoors.

Plant height

Inside the plant reaches a height of 70 cm - 120 cm, while outside the plant can even reach a height of 170 cm.

Northern Lights autoflower yield 

You can expect a generous harvest of up to 200 grams per plant. If you grow according to the Sea of Green method, the plants can even yield up to 600 grams per m². For an autoflower this is an amazing yield


Thanks to its CBD and THC content, the Northern Lights is very suitable for those who experience pain or stress. It gives the ultimate relaxing feeling and relieves (muscle) pain. Moreover, it makes you happy and euphoric, without the tendency to become hyperactive. In fact, it makes you feel more dreamy and calm, so that every muscle in your body relaxes. Positive thoughts and feelings then get the upper hand. In short, Northern Lights Autoflower has a calming effect and is the ideal weed to come to yourself for a while.

Side effects

Actually, the Northern Lights weed has no real negative side effects. Still, some people experience dry mouth and eyes. So make sure you have some water at hand. In some rare cases, smokers can get dizzy and experience a slight headache.

Smell and taste of Northern Lights Auto

The smell of Northern Lights is very recognizable. Sweet and spicy with a light citrus scent. The taste of Northern Lights is the typical taste of Skunk, without being too powerful. Lemon is often seen in the taste and remains in the mouth for a while after taking a puff. You can also taste the earthy and pine-like undertones.


Northern Lights Auto is a mix of Afghan Indica, Thai Sativa and Ruderalis (70% Indica / 10% Sativa / 20% Ruderalis). The Ruderalis genetics give these cannabis seeds the designation Autoflower.

This feminized autoflower was developed in the 70s and belongs to the world's oldest and most famous weed varieties. The strain came from America to the Netherlands, where cultivation techniques have resulted in various varieties. By now, the Northern Lights Autoflower seeds are very popular among beginning and advanced (indoor) growers.

Follow up to harvest. I. Read everything about ph, temp, humidity, nuts, etc. I am sure all are very important. I ignored most of what I read. I really just watered regularly, used half level of recommended Fox Farm trio and kept them in the sun for 6-8 hours per day and got a dry yield of 1.5 to 3 ounces per plant. For recreational growing it was as easy as growing my herbs, also on my porch. Friends sampled for me and said the quality was very good. Good couch lock effect. The only thing I would tell anyone is that the actual grow time was 10-13 wks. I don’t know what caused the range to be so different but results were excellent. Very easy to grow. Next time I will experiment a bit more w nuts and training. Thanks I will be back.

Hi Mario, That's great to hear, it's indeed an amazing strain and fairly easy to grow. We'd love to see some pictures! Cheers, Marc

Spear (Verified customer) 2021-07-16

Great service as everyone described. I have never grown any weed before and don’t use. Last time I smoked was ‘72. Wanted some for barter so decided to give NL a try. 6 of 7 germinated and 5 have made it to week 7. Growing outside. All are 2’ with 10-12 buds starting on each. Really easy to grow. I put them into 5 gal w happy frog, water twice a week. At week 4 started watering once a week with 1/2 the recommended mix of the fox farm trio. I will definitely order from WSE again. I am enjoying learning about the growing process and different strains.

Hi Spear, Thanks for the review. I'm glad to hear your expectations have been met! Good luck with your grow and keep us posted! Cheers, Marc

Rick Wiseman (Verified customer) 2021-06-25

Got 2 of these guys for free with my order, let me say, they don’t disappoint. Both have popped and are in the late germination/early seedling stage, like my Bruce Banner, Zkittlez and Critical Purple, I am really excited to see how we do!!! If you are curious as to whether to buy seeds here or not, I say most definitely! You won’t regret it!!!

Lloyd (Verified customer) 2020-07-23

This was the first time with NL, But I was surprised with the current results. I put little effort into these girls. inexpensive soil just added worm casting. I put them into the one pot, no transplanting. Never water them until two weeks and added granular organic fert 6-3-9 into soil. Water every three days with 250 ml. Mist with water and epsom salts once every 4 days days. 35 days into 80 cm high major vegetation. Today the first flower started. The perfect match for any one that what something to grow without all the care and attention compared to some other strains. Can wait to see how she buds out now..

Jeremy (Verified customer) 2020-06-18

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.

Matthew Reischl (Verified customer) 2020-02-15

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.

This strain is amazing, germinating the seeds was very easy after some advise from the weedseedsexpress blog! My first grow is a big success thanks to you guys. Special thanks to David from customer support!

Martijn (Verified customer) 2019-02-21

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

Delorez (Verified customer) 2019-01-22

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.
