What are the therapeutic benefits of Jack the Ripper as a medical strain?

Unlike its elusive and fearsome namesake, Jack the Ripper is a fantastic strain that does not inspire dread or anxiety in medical users. In fact, one of this high-quality strain’s biggest selling points as a medical marijuana strain is its anecdotal ability to alleviate chronic stress.

Along with being a stress reliever, has a reputation in the medical cannabis community for also providing long-term relief from other mental health issues and disorders such as anxiety.

How do I grow Jack the Ripper cannabis seeds?

Jack the Ripper, which can be grown indoors and out, is a relatively easy strain to cultivate, which makes it an option for cultivators of all skill levels from first-time growers to expert commercial breeders. Furthermore, since Pacific Seed Bank is committed to only offering feminized marijuana seeds to its customers, there’s a 90% or so chance of ending up with all female plants.

When grown outside, which is its somewhat preferred environment, Jack the Ripper will thrive in a warm, sunny, and dry setting that also gets plenty of shade. This sativa-dominant hybrid is relatively hardy, so while it won’t endure the frost, it should be ok in cooler-than-usual temperatures.

Grown indoors, Jack the Ripper responds well to the Sea of Green training method, and regardless of where you grow it, you will need to top it early on in its vegetative growth stage and trim and prune as needed.

What do Jack the Ripper cannabis plants look like?

Jack the Ripper plants can reach heights of 6 feet tall, and produce forest green buds that are almost pyramid-like in shape.

While its plants aren’t particularly memorable in terms of appearances, the distinct-looking nuggets that they render are. In fact, one of the things that Jack the Ripper is known for is its impressive quantity of highly-resinous trichomes that thickly blanket its buds from the inside out. As such, you will need to use a good grinder to break your sticky nugs up as attempting to do so by hand will be a massive challenge.

When to harvest your Jack the Ripper marijuana plants

When it comes to harvesting Jack the Ripper, the fact that it’s a pretty low-maintenance strain to grow makes its yields seem even bigger than they are.

Grown indoors, this sativa hybrid usually begins to flower after about 8-9 weeks providing you with an approximate yield of 250 grams per square meter.

If you’re able to grow Jack the Ripper outdoors, you’ll definitely want to as it has the potential to render about 400 grams per plant sometime around late September to the early part of October.

    All of my seeds germinated successfully, and the plants have been thriving. The Jack Skellington strain has provided a happy and uplifting high, perfect for combating mood-related disorders. I would highly recommend these seeds to any marijuana enthusiast.

  2. R. Simmons (verified owner)

    These seeds were extremely easy to grow. All of them germinated without a problem, so there were no dud seeds to contend with. They germinated within a few days, and they were ready to be planted. Mine flowered in about 9 weeks, so I was so thrilled they were ready quicker than I expected. The yield wasn’t the largest, but this MJ is so potent that it didn’t matter.

  3. Charlize Rose (verified owner)

    Jack the Ripper has been an absolute thrill to grow! From its killer name to its killer yield, this strain has exceeded all my expectations. The high is like a creative frenzy, filling me with energy and happiness. The taste is a delightful combination of citrus, pine, and sweet flavors.

  4. Oscar Fields (verified owner)

    Haha don’t worry you are safe! Jack the ripper might sound intimidating, but it’s nothing more than a sativa powered hybrid that’s great for energy levels and taking HUUuuuuge RIPS from the bong. Doesn’t that make you feel better?

    Thanks for the fast shipping Pacific. Love that you all are based here in Northern California!

  5. Daren Moody (verified owner)

    Jack the Ripper has a very nice head rush to it that is not too overpowering and brings out some positive vibes, it is also complimented with a nice light body buzz. The amazing sweet citrus taste really ties the package together making this strain incredibly worth growing.

  6. Arjun Patel (verified owner)

    Hits pretty hard and fast….provides that dope sativa high that I CRAVE!
    Ten plants yielded me over 1000 G of pot. I HIT THE JACKPOT!
    I am curing my weed to retain freshness. Very much excited for the next growing season.
    Excellent growing advice on the blogs.

  7. Abbie Carr (verified owner)

    Don’t be hating on Jack the ripper. This weed is probably one of the better sativa joints out there. I bought 10 seeds and grew all of them over the summer. One of them didn’t germ, but Pacific replaced for free!! My other seeds looked GREAT, and absolutely stunning in the yard. Can’t be a grower without product, and now I am climbing mountains of BUD!

  8. Elowen Nyx (verified owner)

    Sounds a bit violent, but it is not! Jack the ripper is merely a standard indica with a fancy name. Makes me feel tired and sleepy, usually makes me hungry too. That is why I grow it outside, and why I grow veggies and herbs to use with it! MY freshest and biggest yield yet was this past summer. I was able to secure over 500 G of pot from just 3 plants. I’ve got a few tricks up my sleeve now, mostly cause of these handy dandy blogs that have great growing advice, heck yes!

  9. Thiago B (verified owner)

    Jack the ripper is much like a super charged jack herer. This nug sends me soaring! A very light and uplifting buzz, gives me a lot of focus and creative energy!

  10. Hollie Lee (verified owner)

    Wow this weed really knows how to get me blazed. I took 2 hits of the stuff the other night and….wow I was stoned for literally hours, rambling with my partner about anything and everything…she was very sweet letting me just be a total wierdo….but yeah, all thanks to Jack the ripper lol.
    5 seeds delivered in the mail, all of them sprouted, so that’s cool. It was easy to care for them, and I recommend it to any new growers out there.

  11. Jax Bell (verified owner)

    How profound! I love jack the ripper for its incredible smokeability. This is the BEST weed to smoke out of a bong, hands down. The sour and sweet flavors, and the smooth creamy smoke make for an unforgettable high! I am just so happy I was able to grow this myself. It’s saved me so much $$!

  12. Keyaan Foreman (verified owner)

    The name of this strain actually fits quite nicely cause my name is Jack and I RIP the bong every time I smoke this weed. A very smokeable variety if that makes sense….the flavor is a cross between skunk and pine forest, and the flower is beautiful!!! Never seen anything so full of color and life. It’s put hope back in my soul!

  13. Connah Boyer (verified owner)

    Pretty tasty weed. It’s like everything I ever wanted but never had the courage to seek. Now it is my time to shine. I bought 15 seeds online. They were in my mailbox in just a matter of days wow! They planted like little marbles and grew taller than me. WOW!

  14. Rowena Watkins (verified owner)

    Jack the ripper might sound scary, but it’s actually a very chill grow. I like that it helps me manage my pain and anxiety. Doesn’t usually give me a headache or anything. Best when smoked on it’s own or with some coffee to balance the high.

  15. Elize Wilkinson (verified owner)

    This sativa dominant strain is gonna get you “Jacked” up and it kills your stress just like the famous serial killer haha. Bought my seeds online, 5 of them to be exact, they came in a lovely little package and I followed all the growing advice I could find online. 6 months later I was swimming in fresh bud! The smell is something unique, spricy and earthy, and the taste is nice and harsh. Give it a try.
