What are the effects of Jack the Ripper cannabis?

  • Uplifted
  • Happy
  • Euphoric
  • Energetic

Low-maintenance Jack the Ripper and its relatively rapid grow time will provide growers with incredible plants that contain a sativa-to-indica ratio of 70:30, and a solid THC content that tends to be right around 15%.

Cannabis child of Space Dude, which happens to be a phenotype of the highly-venerated Space Queen, and Jack’s Cleaner, Jack the Ripper is a lemony-citrus sativa-dominant hybrid that many a recreational has in their roster of wake-and-bake strains.

While this fearsome namesake of a strain could make you think you will need to run to the hills to get away from it, in reality, Jack the Ripper is instead more likely to have you happily running in the hills after combusting or ingesting it.

This fabulous strain is known for being energizing and uplifting both mentally and physically–keeping users in high spirits as they giggle and go about their day with a greater sense of purpose and determination.

As a deeply euphoric strain, Jack the Ripper’s positive vibes will have you feeling at one with the world around you as you marvel at the beauty of your life and the world around you.

This refreshing and motivating sativa is renowned not just for its long-lasting upbeat effects, but also for its creative cerebral effects that may end up helping users think outside the box and apply their new ideas to whatever project(s) that they are needing or wanting to accomplish that day.

Or, if work isn’t on your list for the day, then Jack the Ripper makes for a great guest to bring to a party that will have you and your mates laughing and giggling the day or night away.

All in all, this fabulous sativa hybrid is the total opposite of being a terrifying terror, and instead is all about spreading love and good cheer, and providing users with renewed vivacity and mirth.

What are the therapeutic benefits of Jack the Ripper for medicinal users?

Who knew that with a name that once, rightly, struck fear into the hearts of many a woman in London over a century ago, the strain named after the serial killer is actually considered to be a highly beneficial medical strain for medical users!

Thanks to its buoyant and blissful effects that are a result of its sativa genetics, Jack the Ripper is alleged by medical users to help ease, and, even at times, temporarily eliminate chronic stress, negative thoughts and feelings, overly-paranoid thinking, and other mood-related disorders.

Even though Jack the Ripper doesn’t contain a massive amount of indica, it is still reported by many to have some useful pain-relieving effects for patients suffering from physical health ailments such as chronic pain, joint aches, cramps, muscle spasms, migraines, and inflammation.

Finally, because Jack the Ripper has the potential to increase one’s appetite, it may be quite useful to those who are undergoing chemotherapy and/or radiation.

What does Jack the Ripper smell and taste like?

Jack the Ripper boasts a uniquely lovely aroma and delicious flavor profile.

Smelling so strongly of lemon that the hairs of your nostrils just might curl (figuratively that is), Jack the Ripper’s sweet and pungent lemon fragrance won’t just fill your nose and the room you’re in, but it will “stick” to your clothes, the air, walls, furniture, etc. long after you’ve stopped smoking it.

In terms of its flavor, many describe Jack the Ripper’s wonderful taste as being that of fresh, crisp pine; sweet and sour lemon, with some earthy undertones. Those who like to combust their buds tend to notice its sharp and almost buttery flavors before all of the ones described in the previous sentence.

How do I grow Jack the Ripper cannabis seeds?

Don’t let the fact that Jack the Rippers requires being topped early on, consistent pruning and trimming, and some careful climate control fool you into thinking that this sativa can only be successfully cultivated by someone who is at an expert grower level, as it’s actually considered to be a suitable choice for first-time growers too. In addition, since Growers Choice only sells feminized cannabis seeds, cultivators are almost 100% guaranteed that they’ll end up with female plants that will provide them with the buds they want and need.

As a feminized strain that can be grown indoors or out, Jack the Ripper will require a mix of consistent exposure to sunlight and access to the shade. Although this is a relatively strong strain in that it can endure some cooler temperatures, know that it will not be able to handle frost exposure.

Lastly, for those opting to grow this sativa indoors, know that it actually doesn’t do well if you try to apply the Sea of Green method to it.

What do Jack the Ripper plants look like?

As is typical for a sativa, Jack the Ripper plants aren’t short. Instead, they tend to reach 6 feet in height when fully mature, which is why it’s so strongly advised that you top it early on–especially if you have limited indoor growing space.

Its buds, which are shaped like pyramids or triangles, are forest green in color and are covered in a massive amount of resinous trichomes. In fact, when it comes time to break them apart, you’re going to need to use a high-quality grinder as its nuggets are near-impossible to break apart by hand.

When to harvest your Jack the Ripper cannabis plant

While Jack the Ripper is beloved and notorious for its effects, fragrance, flavor, and ease of growth, it’s probably not going to win any awards for the size of its indoor yields.

When cultivated inside, this sativa-dominant hybrid’s approximate yield of 250 grams per square meter should be ready for the picking after 8-9 weeks of flowering.

If you’re able to grow Jack the Ripper outside, you’ll probably want to, as its harvest sizes are significantly larger compared to its indoor yields. Usually, sometime between the end of September and early October, this sativa should bless its growers with a much bigger yield of 400 grams per plant.

    So I’m not a heavy-hitting kind of smoker, I like more mellow THC levels. If you are anything like me in that case you will love this seed. Growing this went by moderately easily, I did a lot less work than I do with other plants and that was pretty great. Growers’ choice seems pretty reliable from what I’ve bought from them.
