The Blueberry Jack strain, which you can also know as the Blue Jack, is a child of the prominent Jack Herer (sativa) and Blue Dream (sativahybrid). This hybrid has a sweet berry flavor with some piny savor. The buds are compact and densely covered with brown trichomes. As it is a sativa-dominant strain, its effects are very typical for its parent Jack Herer: it provides you with physical relaxation and gets rid of bad mood, stress, and anxiety. If you consume it in the morning, it can keep you motivated and energetic throughout the whole day.
