Jack F1 Strain Overview
Jack F1 is a Dutch crossbreed between Northern Lights, a Skunk F1 and a Mexican Haze developed by Spliff Seeds. She is the result of a long and arduous selection process to obtain suitable phenos as parents. We took several generations of thorough back-crossing to her original parents to stabilize the strain, making it a first-generation (F1) hybrid that consistently produces stable genetics. This 75% sativa-dominant strain produces very imaginative and energetic sensations, while simultaneously relaxing those tense nerves. Despite its sativa dominance, Jack F1 has an Indica appearance, but is definitely a Sativa, displaying the unique characteristic of looking like an indica plant while providing classic sativa effects.
Spliff Seeds Jack F1 is a cupwinning variety and won the 2 Place at the Highlife Cup 2010 in the category Bio, demonstrating its quality and recognition in the cannabis community. Huge resin production. Jack F1 is covered in snowy crystals of resin from top to bottom, making it particularly attractive to both recreational users and those seeking medicinal benefits. The strain is notable for its distinctive aromatic profile, featuring cinnamon aroma and sweet and spicy flavor, with the sweet and spicy flavor, with a touch of haze, is very pleasant and enjoyable.
