J1, or Jack One, is a high-end hybrid strain that’s gaining widespread popularity. Although a hybrid, the effects categorize the strain more on the sativa end of this scale. J1 is a cross between two famous sativas, Skunk #1 and Jack Herer, and is famous for its powerful, uplifting buzz which allows for mobility. The flowers are emerald green and frosty with a sweet odor resembling the unmistakable Jack Herer pungency. The apparently only flaw of this strain is the top-shelf price that tends to come with its exceptional quality.
