The feminized Jack Widow genetics will generally provide excellent results. Whether it's grown indoors or outdoors. Jack Widow plants are stable and very robust under most conditions. The flowering time is about 9 to 11 weeks and with the total cycle the plant will reach a maximum height of about 120 cm. During the flowering stage thick buds will develop and yields can reach up to 650 grams per m2. The female Jack Widow strain is suitable for methods like SOG (sea of green) and SCROG (screen of green). Outdoors the plant is generally ready to be harvested around mid October. Besides the plant can grow up to 3 meters tall and yield as much as 1000 grams per m2 under the most optimal circumstances.

Advantages and points of interest

When opting for feminized seeds growers won't have to remove their male plants which makes growing feminized seeds much easier compared to the cultivation of regular seeds. However, the plant is susceptible to failures in the diet. In addition, the level of fungal resistance of this strain is "average". 

For what use is Jack Widow weed suitable and what is the effect of the strain?

Jack Widow is great for recreational use. Aromas are delicious citrus-like and very fruity. The narcotic high of this dominant Sativa (80%) is strong, but very pleasant. Because of the high THC content the weed has a pleasant effect on both the mind and body.

    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

  4. Bryant hernandez (verified owner)

    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

  5. E. Kidder (verified owner)

    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.
