Monster Cookies is an indica-dominant hybrid that builds on some strong and flavorful genetics. This strain is a cross between the omnipresent Girl Scout Cookies and the flavorful and eye-catching Granddaddy Purple. This background gives the flowers a relaxing high and a complex, fruity taste. Although it’s known to be a potent variety, cannabis testing lab Analytical 360 has found Monster Cookies to have a modest range of 10% to 15% THC composition.
