About Jack the Ripper F3 R
This F3 generation from Subcool Seeds comes from crossing preserved breeding stock back into a Jack the Ripper F2 selection, part of an ongoing effort to stabilize and refine one of the seed bank's signature lines. Genetically it sits at 60 percent sativa to 40 percent indica, finishing flowering in 8 to 9 weeks with indoor plants reaching 100 to 150 centimeters for 400 to 500 grams per square meter, all rated a moderate difficulty. THC is comparatively restrained, capping at 15.5 percent, considerably lower than many contemporary sativas, which fits with Jack the Ripper's reputation as a strain valued more for its lineage and stability than raw potency. Regular seeds mean growers will need to sex their own plants, standard practice for a stabilization project like an F3 generation still being refined for consistency.
