g13 

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.

G13-Haze 

It's a type of marijauna, that has been crossed with G13 (govenmentally grown marijuana), and Haze.

Last night I smoked that G13-Haze, and I was high 3 months later. That's some good shizz!

G-13 

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.
