Purple Jack is a sativa-dominant cross between well known strains Jack Herer and Purple Kush. These medium green buds have dark leaves and a generous supply of crystals coating them. A lovely flavor of grapes and berries with hints of floral tones enhance the creative sense of euphoria and focus Purple Jack brings. Purple Jack treats chronic pain and stress well, while being a great choice for insomniacs. Purple Jack works well against depression also.
