About Jack F1

Spliff Seeds built this F1 by crossing Jack Herer with a Reclining Buddha and Northern Lights #5 pairing, a three-name pedigree that leans the plant hard toward its sativa side, eighty percent by their own breakdown, while still finishing in a comparatively quick 7 to 8 weeks. Indoors it grows to a manageable 80 to 120cm and returns 450 to 550 grams per square meter under a moderate grow difficulty rating, while outdoor plants stretch taller, 150 to 200cm, and can produce 500 to 600 grams per plant given the space to do it. THC tops out at 22 percent, a strong ceiling for a sativa-leaning cross with this much lineage transparency behind it. No effects, flavors, or terpene data have been published yet, so what's currently on offer is a fully documented growing profile paired with an unusually specific parentage, rather than a finished sensory writeup.
