Jack the Ripper

Jack the Ripper Marijuana Strain Overview

History & Lineage: Jack the Ripper is a Sativa-dominant hybrid created by legendary breeder Subcool, founder of TGA Genetics (The Green Avengers). The strain was bred by crossing Jack’s Cleaner, a renowned sativa strain with lemony attributes, and Space Queen, which is known for its unique blend of resinous traits and high THC content. This combination has given Jack the Ripper its vigorous and potent effects, along with a distinctive citrusy, earthy aroma.

Subcool originally aimed to create a strain that would produce copious resin and deliver a clear, euphoric high—traits that would appeal to both recreational users and medical patients.

Lineage:

  • Jack’s Cleaner x Space Queen
    This lineage blends the legendary sativa genetics of Jack Herer with Space Queen’s powerful resin production and potency, making it a standout in both breeding and consumption communities.

Terpenes: Jack the Ripper’s dominant terpenes give it a sweet lemon and pine aroma with earthy undertones. The top terpenes include:

  • Limonene: Provides the signature citrus/lemon scent and offers uplifting and mood-boosting effects.
  • Pinene: Adds to the pine and earthy notes while promoting focus and alertness.
  • Caryophyllene: This peppery terpene adds a hint of spice and contributes anti-inflammatory properties.

These terpenes not only contribute to Jack the Ripper’s refreshing flavor but also offer therapeutic benefits, such as stress relief and anti-anxiety properties.

Potency: Jack the Ripper is known for its high THC content, generally testing between 17% and 24%. Its strong sativa effects produce an energetic, cerebral high with uplifting and euphoric sensations. Users often describe feelings of creativity and clear-headedness, making it an ideal strain for daytime use. Despite its potency, it has relatively low CBD content, so those seeking heavy body relaxation or pain relief might opt for a different strain.

Effects:

  • Energetic
  • Euphoric
  • Creative
  • Uplifting

Because of these effects, Jack the Ripper is often recommended for those dealing with stress, depression, or fatigue, and for those seeking motivation and creativity.

Yield Statistics: Jack the Ripper is a medium to high-yielding strain, making it popular among both home growers and commercial cultivators. It performs best in outdoor environments or large indoor setups, as it has a sprawling structure with tall, lanky branches that benefit from training and support. Growers should expect:

  • Indoor Yield: Around 12-16 ounces per square meter.
  • Outdoor Yield: Can reach 16 ounces or more per plant, depending on conditions.

The strain typically flowers in about 8-9 weeks, which is considered a fairly quick cycle for a sativa-dominant hybrid. Its resin production is impressive, making it a favorite for those interested in creating hash or concentrates.


Summary: Jack the Ripper is a well-balanced sativa-dominant hybrid known for its powerful effects, uplifting and energetic high, and rich resin production. With a lineage rooted in sativa classics like Jack’s Cleaner and Space Queen, this strain is ideal for growers and users who enjoy potent, citrus-flavored cannabis with a fast-growing cycle and good yields.
