G-13, supposed "King" of all marijuana strains. Story goes that in the 60's the government procured the best strains of MJ throughout the world, took 13 generations to finally produce the MJ strain. Other myth's follow a similar scheme, G(government)13-alphabet-M(marijuana) A slightly more believable story is G-13 was created at University of Washington's cannibis facility. Once again no proof to support any of these "Myths"
Fact: The G-13 strain has been reported to contain THC levels of 28% by mass. This is nearly double THC%/mass than other high grade sinsemillia grown plants. Purple Haze,Kush,Blueberry,Northern Lights, etc...
