JackMatic is an autoflowering feminised seed from Black Skull, created by crossing SkullRyder with a quicker-finishing take on Jack Herer. Its make-up leans towards sativa, with indica and ruderalis influences alongside, so it suits growers who enjoy a plant with character. Plants grow to a noticeable height and begin to show flowers roughly three weeks in, after which the buds form in dense clusters. The aroma is bright and citrusy, with warm spicy edges and a pine-like backdrop. Because of its Jack Herer heritage it may take a touch longer to finish than some other autos, yet the reward is a smoke that feels more cerebral than many fast-flowering alternatives. THC is stated at between 15% and 20%, placing it among the more potent options within the autoflower range.
