Critical 47 is hybrid in genetics and by name. A sweet, skunky cross between Critical Mass and AK-47 Critical 47 has a reputation for its pungent aroma and happy, relaxing effects. The rapid finishing time and flavors of mango, peach, and vanilla make Critical 47 a treat for growers and consumers alike. It is a great strain for cloning due to its small internodal distance and thick branches. However, its strong odor encourages the use of carbon filters when grown indoors.
