Jack F1 reg

Average rating: 2.9 (203× ratings)

Sativa-dominant. Skunk #1 x NL x Mexican Haze. Huge resin production. Massive budding beast.

Jack F1 is a cross between Northern Lights, a Skunk F1 and a Mexican Haze. Spliff Seeds needed several generations of thorough backcrossing to its original parents to stabilize the strain, allowing further generations to give virtually identical offspring. The final result is their Jack F1: a crystal-covered sativa dominant plant.

Jack F1 has an indica appearance and flowering period, but it is definitely a sativa. Despite its potency, this strain produces very little odor while growing.

Stick to advised nutrients and don’t overfeed, especially during the vegetative period. Spliff Seeds advise a shorter veg period if space is an issue. Preferably grown in soil or coco with plenty of space. It will form one giant main cola, so don’t prune her. Bud structure is clearly influenced by its Mexican Haze roots, chunky, large and compact.

Jack F1 has a sweet, spicy smell with a hint of cinnamon. The taste is sweet and spicy with a touch of haze. Highly medicinal strain that can be used to combat stress, depression, muscle-/joint- and neuropathic pain.
