Emerald Jack is a cross between: Jack Herer and Emerald OG. The new Sativa dominant hybrid grows fast and tall, and doubles its size after moving into the flowering cycle. In order to get full plant potency, healthy doses of nitrogen, calcium and magnesium is required. The reward is thick harvest of resin-encrusted colas. Flowering time takes 9 to 10 weeks. Emerald Jack has tropical fruit salad taste that combines with intense sourness and creates exceptional tangy flavour. The effect is uplifting, spirited and stimulates creativity.
