Whether you have a nostalgic yearning for the Amsterdam of the 90s or a loving cannabis student looking for rare gems, Jack Widow seeds is what you are looking for.

The famous Jack Widow is the union of the best clone of Jack Herer from Amsterdam and of the best clones of White Widow. Bred in the respective golden age of their genetics, these two celebrities united in one strain guarantee the authenticity of a breathtaking experience.

Much easier to grow, faster than Jack Herer and much more generous than White Widow, Jack Widow offers the best of both worlds.

Note: is this your very first time growing cannabis? Guarantee yourself a successful harvest by buying autoflowering Jack Widow seeds.

Why you should buy Jack Widow seeds:

  • Huge yield potential
  • High THC levels
  • Delicious taste and aroma

Growing Jack Widow (indoors and outdoors)

With the feminized Jack Widow seeds you have some excellent producers in your hands, but you need to have green fingers because she requires proper handling and is not happy with (nutritional) mistakes.

Jack Widow seeds are therefore classified as moderately difficult to grow. A challenge, but definitely doable, so don't be put off. In any case, the plant will reward you with a well-deserved and excellent tasting supply of weed.

Flowering time

Despite its Sativa dominance, the flowering time is only 63-77 days, making it a very interesting Sativa dominant strain.

Plant height

The plants become relatively tall, with a height of up to 120 cm indoors, but this of course depends on the growing method and pot size. Outdoors, she can grow up to 3 meters tall!

Jack Widow yield

Maximize yields by applying training methods like SCROG and FIM to Jack Widow. Her solid architecture and honorable cloning performance also make her a workhorse in SOG, where she can offer you her highest yields (650 gr/m² indoors) in record time. Outdoors it is even possible to harvest huge yields of 1000 gr/plant. Especially if you have experience and grow in a warm climate.

For a more therapeutic effect, we recommend harvesting after the 7th week. If you prefer a more relaxing effect, we recommend harvesting from the 8th week. Outdoors, you can harvest the first buds of this Jack Widow in the middle of October.


As you can expect from her parents, this strain produces a strong weed with a very high THC content that can reach up to 21% in the hands of a skilled grower. Therefore, this is not a weed to wake up to on a quiet Sunday morning. Due to the considerable Sativa influence, the high is still energetic despite the high THC percentage, and you don't have to worry about a possible couch lock.

Jack Widow is also known to lift the spirits and relieve you of pains throughout the body, starting at the base of the neck, working down the spine. It can also promote social relaxation, helping people to become more chatty and lively. Many reviewers have additionally noted that this strain is effective in relieving nausea and insomnia.

Side effects

Aside from the familiar dry mouth and eyes, Jack Widow can induce dizziness or anxiety when smoked in higher than normal doses.

Don't be surprised if the munchies strike either, as her THC content is over 20%. 

Smell and taste

The aroma is that of sweet citrus fruit, which is due to the Haze influence of the Jack Herer, with undertones of vanilla and eucalyptus. Exceptionally delicious! You will also find the hazy and fruity notes of Jack Herer as the sweet and voluptuous hashish flavor of White Widow.


Jack Widow is a cross that was chased for a long time in Amsterdam. A cross made between one of the best Jack Herer in Amsterdam and a White Widow from the best Dutch lines.

As the name suggests, Jack Widow is a hybrid cannabis strain and the product of the world-famous White Widow and the equally famous Jack Herer plant.

JW has become my default strain over the years and to be honest. The seeds from Weedseedsexpress.com are the best so far. Never heard of this company before, but from my experience I can say that there genetics are great. Received the seeds neatly packed in a discrete package and within just 8 business days. So if you are looking for good services I would definitely recommend to buy here.

I have grown Jack x White widow twice seeds, but this time I bought some more seeds. My garden looks amazing now. Can't wait to harvest that shit. Last time i smoked this weed played mario card for hours and hours. Never had a chance, but didn't give a shit

Bryant hernandez (Verified customer) 2018-03-20

Can't say it is my absolute favorite strain when you look at the effects and tastes, but the yields are very very good. A must if you are a Sativa fanatic

E. Kidder (Verified customer) 2017-12-07

After a few beginner strains it was time for me to choose something more challenging. I must say Jack Widow wasn't that hard to grow, but the plant does indeed need some more attention. Indoors my strains reached a height of 105 cm and yielded upto 500 grams per m2 so i'm really happy with that.
