Feminized and photoperiod-dependent version with an ultra-fast flowering of one of the first and most appreciated strains of our catalogue, our Black Jack®. This F1 hybrid is the result from the cross between a selected genetic line of S.A.D. Sweet Afghani Delicious Auto® and the Jack Herer elite clone used in the original Black Jack®.

Just like the original version this strain produces very potent and productive plants, with strong side branches that are very long and fully loaded with aromatic flowers. The aroma is very sweet, featuring hints of incense complemented by lemony citrus tones. This version shortens the flowering time by one week compared to the original version.
