GG#4 is well known to have a high THC content due to its complex backcrossing of Sour Diesel, Sour Dubb, Chocolate Diesel, and Chem’s Sister. A truly great breed, this slightly sativa dominant strain has recently won awards at Cannabis Cup around the country. The aroma is a powerful diesel with hints of chocolate while also enjoyably earthy. Its most common effects are best suited at night when it’s time to relax and cool off.
