Product Summary
Jack the Ripper F3 represents the next stabilized generation of Subcool’s legendary lemon sativa.
Resin-heavy, structurally consistent, and intensely terpene-driven, this preservation release delivers the classic Jack the Ripper experience with improved uniformity and canopy-wide performance.
Genetics & Origins
Jack the Ripper F3 was rebuilt as a preservation project following Subcool’s passing.
Original Jack the Ripper F1 stock had been entrusted to Irie Genetics, who later returned preserved F2 keepers. From these F2s, uniform, resin-heavy Xmas tree phenotypes were selected and used for a careful seed increase.
The result is a faithful continuation of Subcool’s original vision, maintaining potency, terpene intensity, and structural consistency while reinforcing genetic stability.

The high is classic Jack the Ripper, fast-hitting, uplifting, and cerebral with a long-lasting, grin-inducing ride.
Mental stimulation comes on quickly and remains energetic and expansive, making this cultivar best suited for experienced consumers and daytime or creative use.
Flavor & Aroma
Top notes: Loud lemon cleaner
Heart: Hashy citrus funk
Finish: Sharp, lingering citrus
The terpene expression is unmistakable, delivering the aggressive lemon profile Jack the Ripper is famous for, paired with depth and pungency that fills the room in late flower.
Growing Information
Jack the Ripper F3 produces medium-to-tall plants with strong lateral branching and a dominant Xmas tree structure. Phenotypes are consistent, with glassy resin coverage and heavy-stacking colas that require support late in flower.
This cultivar responds exceptionally well to early topping and training and thrives indoors under strong lighting with controlled canopy spread.
Medical & Recreational Benefits
Commonly reported uses include mood elevation, mental stimulation, creativity, and daytime motivation.
