A member of the Girl Scout Cookies (GSC) family, the Monster Cookies strain is considered an Indica-dominant hybrid. It is often recognized for it’s soothing, relaxing effects, combined with shades of the classic GSC taste. Monster Cookies Strain: Girl Scout Cookies X Grand Daddy Purple It’s no secret that the Girl Scout Cookies (GSC) strain has gained a great deal of popularity in recent years. Much like OG Kush, it can be difficult to know the exact lineage of each member of the GSC family. Sure enough, the Monster Cookies strain has a somewhat murky genetic lineage. I’ve heard suggestions that it is simply a phenotype of the original Girl Scout Cookies strain. Of course, this is a distinct possibility considering that there are plenty of GSC phenotypes floating around (the Thin Mints cut, the Forum cut, etc.) However, I’ve also been told that the Monster Cookies strain was the result if crossing the Girl Scout Cookies and Grand DaddyPurple strains. Judging from the characteristics of this batch of Monster Cookies, I would have to agree.
