Genetics & Origin of Jack the Ripper
Jack the Ripper comes from Subcool, the breeder behind TGA Subcool Seeds. He relates that after six years of breeding work he started over again with two new lines. JTR is the first of these outcrosses and combines his JC line with a Space Queen male; according to Subcool, the phenotypes show strong Jack's Cleaner traits. As he describes it, the JC side dominates with a heavy structure and potency, while Space Queen contributes a sweet mango aroma and softens the harsh smoke. He lists the lineage as Pluton × Purple Haze × Lambsbread × NL × Jack Herer × Romulan × Cindy99. He gives the ratio as 80% Sativa and 20% Indica and calls the phenotypes moderately stable. This product contains feminised, photoperiod seeds. You will also find Space Queen by Brothers Grimm Seeds in our range.
Who Is Jack the Ripper For?
Jack the Ripper is a distinctive Sativa with a powerful citrus profile. It suits:
- Sativa fans looking for an intense, trippy high
- Growers with enough room height for strongly stretching plants
- Lovers of lemon, mango and hashish aromas
- Collectors of American genetics
- Growers for whom resin and potency matter more than yield
It is less suitable for low rooms and for consumers who react sensitively to strong Sativas – the breeder himself names an increased heart rate and paranoia as possible side effects. You can find more strains of this origin under US genetics.
Growing Jack the Ripper: Indoor & Outdoor
Indoor Growing
Subcool describes Jack the Ripper as a large plant with a long stretch whose colas only swell late. His recommendation: top the plants and send them into flower early so that the height stays manageable. Flowering takes around 63 days; the breeder gives the harvest window as 8 to 10 weeks. He rates the yield as medium and the trimming effort as moderate; he gives no figures in g/m² or a height in centimetres. Because the phenotypes are only moderately stable, individual plants can differ in growth and ripening. So judge ripeness by the trichomes rather than the calendar. You will find the basics on training and managing the flowering phase in the Growpedia.
Outdoor Growing
The breeder also lists the strain for growing outdoors but states neither a harvest date nor a yield per plant. Expect tall plants that need plenty of space and a sunny spot sheltered from the wind. As the flower clusters only gain mass late, a spot with a long, dry autumn is an advantage. You can find more strains for outdoors under feminised outdoor seeds. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Jack the Ripper
Subcool sums up the aroma as lemon, mango, pine and hashish; the flavour reminds him of lemon hashish. He attributes the citrus note to the JC side and the sweet mango aroma to Space Queen. The manufacturer does not give a lab terpene profile. He describes the effect unusually openly: intense, trippy and visual, with increased appetite – but also with an increased heart rate, possible paranoia and a heavy crash at the end. This fits his assessment of "extreme potency"; there is no THC value as a percentage, and the strain is merely listed as THC-dominant. If you consume only rarely, you should approach it with caution. How strong the effect is depends on dose and individual tolerance.
