XJ-13 is the legendary Sativa that helped define THC Design, a Jack Herer x G13 Haze cross known for its bright terpene profile and smooth, motivating lift. The flavor is clean and vibrant with notes of lemon zest, sweet tangerine, and fresh pine, while the aroma layers citrus peel, earthy herbs, and a touch of floral haze. Powered by Terpinolene, Caryophyllene, and Ocimene, the effects are soaring and cerebral with an energetic, euphoric focus that makes this cultivar a go-to for creativity, conversation, and daytime productivity.
