Jack F1: The First Generation Jack

Jack F1 is a first generation hybrid developed by hybridizing Skunk #1 with Northern Lights and Mexican Haze. This 75% sativa-dominant strain produces very imaginative and energetic sensations, while simultaneously relaxing those tense nerves. With high concentrations of THC, Jack F1 can definitely induce potent highs. After heating the buds, the spicy and sweet aromas are unleashed.

Jack F1 reaches anywhere between 150–300cm in height depending on the phenotype, expertise of the grower, and whether it grows indoors or outdoors. This variety grows like a classic sativa, however, its appearance resembles indica-dominant strains. After 9-10 weeks of flowering, Jack F1 produces a significant amount of resin and the yields amount to around 350–450g/m².
