The CGC XJ-13 is a sativa dominant strain and is a cross between G13 Haze and Jack Herer. It is one of the most clean and smooth strains you can possibly get your hands on. Not only is it a classic hybrid, but it has plenty to offer at the same time. With 18% THC and 1.95% CBD content, it is the perfect strain for individuals who are medicating with cannabis for the very first time.
