Emerald Jack was born in California when breeder Emerald Triangle Seeds crossed Jack Herer with Emerald OG. The combination created this high-THC, low-cannabidiol (CBD) plant, according to Amsterdam Seed Center. Emerald Triangle says the buds grow thick and resin-covered with a sour, fruity flavor. The breeder says Emerald Jack produces energetic, uplifting effects.

Grow Information

The mostly sativa Emerald Jack grows tall and gangly, and performs well with supplemental nitrogen, calcium, and magnesium. It is resistant to bud rot and flowers in nine to 10 weeks indoors or in mid-October outdoors in the Northern Hemisphere, according to Emerald Triangle.
