JACK THE RIPPER F3 | SUBCOOL SEEDS | PHOTOPERIOD CANNABIS SEEDS REGULAR

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.
