Product Summary

Jack Skellington F2 is a vigorous, high-yielding sativa-dominant hybrid born from the legendary Killer Queen and Subcool’s Jack the Ripper.

This open-pollination project preserves everything that made the original drop special — soaring effects, massive resin production, and citrus-drenched pine aromas that punch through even in veg.

Selected from a 100-seed population and narrowed down to the top 25 plants, this F2 line offers slight pheno variation with consistently heavy yields and trichome-coated spear-shaped colas.

Ideal for fans of classic Jack terps and creative, high-energy effects.
