An urban legend that has been going around for at least 15-20 years. g13 is supposed to be a super-pot the government created for research. Renewed interest was brought in because of the movie American Beauty and how g13 is used in it.
In American Beauty, Lester (Kevin Spacey) buys g13 from his neighbor's son.

According to the legend, "G" stands for "Government" and the 13th letter of the alphabet is "M"( for marijuana). This strain was purpotedly pinched from the US government's Marijuana Research Facility in Mississippi. I've researched high and low and found no credible source to substantiate this story, other than High Times magazine. A very strong, pure indica, G-13 is most often crossed with other varieties to augment its low yield and fair taste. The taste is hashy, spicy-to-bland flavor. The smell has little fragrance, and its high is a trance-like body stone. It is very potent, sometimes more than 25% THC. Its easy to grow, has a fair yield, and is easy to manicure. Flowering time indoors is 55-60 days, outdoors is mid- october to early November. A legendary strain.
G-13 is extremely dank and can kill a noob in 2 hits.

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...
