Growing Jack Widow autoflower (indoors and outdoors)

Jack Widow autoflower seeds offer many advantages that are trusted by hundreds of our regular customers. First, the seeds are feminized, which means that the strain is female and will not develop male plants. In addition, the autoflower genes ensure that the plant will flower automatically which greatly facilitates the growing process. 

The previous generation of autoflowers often started to flower (too) quickly. This caused a problem because the plant was not able to reach a decent height. However, this problem has been solved with this new generation of "Big autoflowers" of which the Jack Widow autoflower is a part. We all know what "Big" means, and so does the size of this autoflower. These autoflowers, on the other hand, are programmed to start flowering only after a thorough growth phase. As a result, this new generation of autoflowers will be larger and therefore also yield an extra large harvest.

The Auto Jack Widow is a stocky plant with some thick green leaves covered with a brilliant layer of whitish resin and buds with lots of orange trichomes. During flowering the smells can be pungent, so we recommend using a good quality filter if you are growing indoors.

Flowering time

The flowering period lasts on average between 11 and 13 weeks.

Plant height

As the name suggests, Jack Widow Autoflower seeds have the potential to grow into large female plants of up to 1.8 meters tall outdoors in a period of 105 to 121 days.

Grown indoors, the strain will grow between 80 and 150 cm tall.

Jack Widow Autoflower yield

This stable hybrid produces excellent harvests of large buds - up to 150 grams per square meter indoors and 250 grams per square meter outdoors. This makes her a very effective plant for indoor and outdoor growers in the Northern and Southern Hemispheres.


Auto Jack offers pleasant highs and leaves you with a wonderful feeling of time. The smoke leaves a pleasant taste in your mouth, and with a few small bites on hand, Auto Jack Widow is absolutely perfect for enjoying a movie.

With the measured strength of it's high, this cannabis strain will appeal to old-school users and new smokers alike. 

Side Effects

Although unusual, you may experience dry mouth, dry eyes and some dizziness as side effects.

Smell and taste

The aroma of Jack Widow Auto is subtle and infused with sweet undertones with scents of pine and cedar at the same time. There is also an underlying dank earthiness that comes through when you crumble it between your fingers. 


The Jack Widow Autoflower strain was created from a cross between Jack Herer and White Widow, two legendary cannabis names, to which some Ruderalis was added to create an autoflowering hybrid. The combination of these classic cannabis strains, from which this plant emerged, produces an amazing high that never fails to take your worries and concerns away.

As you would expect, Jack Widow Auto inherited the best of both strains. The autoflowering element comes from Ruderalis, a truly stunning cannabis strain capable of establishing itself beyond the Arctic Circle, thanks to the automatic flowering cycle that has evolved naturally over millions of years of evolution. These genes give Big Jack Widow Auto short, consistent growth and fast flowering.

As for White Widow, which is also a legendary strain, is famous for her exotic power. She offers a sugary crystal layer with intense trichomes that will cover the buds.

This strain was chosen primarily for its power, as White Widow flowers quickly and produces equally abundant yields.

Harry (Verified customer) 2019-10-14

I'm very curious how this strain works out. White Widow and Jack Widow are both really nice separately, so cant wait to smoke their baby! Shipping had a little delay but all cam in well and was super stealth. So far I had no issues germinating them. So far so good 😄😄

Derrick Erving (Verified customer) 2019-08-22

Would have given 6 stars if I could because 6 out of 6 germinated and thanks David for all your kind support. It's just a blessing to see that there actually do exist customer care teams that actually care about their customers so I reward you with a new customer for life and i will definitly share your website with anyone. Take care and talk soon

Mark (Verified customer) 2019-07-22

Just finished an outdoor batch of these. WOW is what I say. Fruity aroma during flowering, but touch these beauties with your hands and out comes a big time sour/ sweet smell. The only time I’ve ever asked another man to smell my fingers was during trimming these LOL. Thanks for a great grow weedseedexpress!

Hamiltongeorge (Verified customer) 2019-06-08

My seeds arrived today after the first package was intercept (F*stupid government) but you guys have made up for it so i'm very satisfied now and will return for more

Edgar Winchester (Verified customer) 2019-05-06

Although i'm a first timer i have a very successful grow with these seeds so i'm really really satisfied. Growing was easy especially because you don't need much knowledge about growing so if you are beginner this is a great choice. Thats for sure

E. Moore (Verified customer) 2019-03-07

Perhaps not so exciting for advanced growers but a VERY GREAT strain for first time growers. Reliable and good yields. No issues with mold or whatsoever.

Bolanos (Verified customer) 2019-02-18

Growing a cannabis plant seemed very difficult to me. Yet that wasn't the case. On David's recommendation I have chosen big jack widow and I am very happy with the final result. The weed tastes fantastic and that I have been able to grow my own weed myself is just amazing. Will definitely order some more seeds soon.

Shed Vega (Verified customer) 2019-01-24

As a beginner and from my personal experience I can say that this is a very suitable choice for those who are looking for ease. The plant requires little maintenance and grows steadily. During flowering, beautiful buds emerge with a lot of THC crystals. I was therefore tempted to harvest earlier, but fortunately I gave the plant its time to ripen. Got some pretty good yields now and the weed taste lovely!!

Colin Stephenson (Verified customer) 2018-12-01

BJW is a great and easy to grow strain for beginners. Didn't had any hard times growing this one. Yields are oke.

N. Lisk (Verified customer) 2018-08-19

I will never choose normal autoflowers anymore. These big auto's are muchhhh better.

Delossantos (Verified customer) 2018-03-24

Very easy to grow and the weed provided a good sativa high which in my opinion is not too powerful. I can not say that this is my favorite, but its a nice weed. Price quality ratio is good

Sergio Sturdivant (Verified customer) 2018-02-27

As a novice grower this species is recommended to me by friends. I do not regret it. Although the flowering time is a bit long, Big Jack is an easy to grow strain and produces good harvests. Therefore I recommend this strain to novice growers.

Vape420 (Verified customer) 2018-01-08

A great cross between Jack Herer x White Widow. A dispensary nearby calls it Apple Jack, I think it is there own branding or something like that. It is a great daytime sativa dominant strain without the sativa negs, like anxiety or paranoia. The flowers are largish but with closely packed sativa buds. A light-dark mottled green bud with light brown hairs. I would classify this as a niche strain, similar in effect to strains like Agent Orange. Growing is pretty easy, and when it comes to the quality of this seed, you can be sure you will get the best genetics at the Weedseedsexpress if you ask me. Thanks fellows!

Harold Hernandez (Verified customer) 2017-10-05

I have grown many autoflowers now, but the Big Jack Widow from Weedseedsexpress is definitly one of my favorites. It's a really tough mold resistant strain with good yields. What i really like about this strain is the high THC content. I made my mind go wild. Definitely recommended.

Mildred Briggs (Verified customer) 2017-02-26

Big Jack is one of those good yielding autoflowers without to much maintenance I was looking for..
