While Lemon Jack has to make the reputation of its father, Jack Herer, this sativa deserves some respect. A potent strain featuring a chemical-like smell that is lemon, Lemon Jack has psychoactive effects that are powerful. Energizing and focused, the effects of this strain draw from both its Jack Herer and Lemon Kush heritage. Just like a cup of java, Lemon Jack is a strain that is daytime. Patients who suffer from fatigue and migraines tend to find relief with this strain, even though it might not be the ideal choice for people who suffer with anxiety.
