The High Garden Cannabis co. cultivates all natural, organic, pesticide free, greenhouse grown cannabis. While Lemon Jack has yet to earn the reputation of its father, Jack Herer, this sativa deserves some respect. A potent strain featuring a distinct, chemical-like lemon smell, Lemon Jack has strong psychoactive effects. Focused and energizing, this strain’s effects draw from both its Jack Herer and Lemon Kush heritage. Like a strong cup of coffee, Lemon Jack is a daytime strain. Patients who suffer from headaches and fatigue tend to find relief with this strain, though it may not be the best choice for those who suffer from anxiety.
