Where does Jack Ripper come from?

Jack Ripper was bred by Subcool of TGA Genetics, the breeder behind several well-known Space Queen crosses. He made it by crossing a Jack's Cleaner clone with a Space Queen male, mainly to get Jack's Cleaner into seed form so more growers could grow it.

The name is a nod to its Jack's Cleaner heritage. It went on to parent other TGA strains, including Pandora's Box, a later cross back to Space Queen.

What does Jack Ripper smell and taste like?

Lemon is the headline. Most descriptions call it sharp and sour, like lemon peel, with pine and a spicy, earthy note underneath. The breeder's own description adds mango and a hashy finish.

One strain database lists terpinolene as its top terpene, followed by myrcene and pinene. Terpinolene often turns up in bright, energetic sativas, and pinene adds the fresh pine. The flavour follows the smell: tangy citrus on the inhale and pine on the finish.

Jack Ripper effects: what people report

People most often describe Jack Ripper as energetic, creative and focused, with a fast, cerebral feel that suits the daytime. Some call it gentle and mellow, while others find it intense and very visual.

These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth is a common complaint, and paranoia and anxious feelings come up more often than with calmer strains, especially for people new to it.

How strong is Jack Ripper?

Jack Ripper is usually listed in the moderate range. One strain database shows about 17% THC and another database gives 15% to 20%, with little CBD. Some listings report batches above 20%.

Because its effects are known to run fast and heady, start with a small amount and give it time before having more. The THC and CBD for your batch are on the label, and they matter more than the strain name.

Buying Jack Ripper in Canada

On labels it's more often written Jack the Ripper or JTR than Jack Ripper, so search for all three. It's also easy to mix up with Jack Herer or Jack Frost, which are different strains.

Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of that lemon smell.

Jack Ripper vs Space Queen

Space Queen is Jack Ripper's parent on the father's side. Both are uplifted, heady hybrids with similar THC ranges, but they smell different. Space Queen leans sweet and fruity, with pear and floral notes, while Jack Ripper is all sharp lemon and pine from its Jack's Cleaner side. Jack Ripper is also more often described as racy. If you like softer fruit, start with Space Queen. If you want a bright citrus sativa, try Jack Ripper.

  • Space Queen: a parent, sweeter and fruitier, with a similar uplifted feel.
  • Jillybean: another TGA strain with Space Queen behind it, smelling of candied orange.
  • Cinderella 99: Space Queen's parent, bright and citrusy with an energetic reputation.
  • Super Lemon Haze: no family link, but the same sharp lemon smell and daytime energy.

Kief and trichomes: what they are and what to do with kiefTrichomes are the tiny resin glands on cannabis flower that hold most of its cannabinoids and terpenes, and kief is the powder of trichomes that falls off the flower, often collecting at the bottom of a grinder.

An eighth is 3.5 g, a quarter is 7 g and a half is 14 g. In Canada, an adult can carry up to 30 g of dried cannabis in public, and other forms count against that limit by an equivalency schedule in the Cannabis Act.
