"G13 is a legendary strain subject to much rumour and speculation".......
G-13 is an extremely strong (i.e. very mind altering) strain of cannabis that is the subject of many urban legends.
Fact: This strain (originally a single clone) was probably of Afghani origin, and provided a very potent smoke.
Fiction: According to one fanciful account, the CIA, FBI, and other agencies procured the best strains of marijuana
from breeders all over the world. At an installation at the University of Mississippi, they bred many new hybrids.
Putting these together, they created a strain that was more powerfully intoxicating than any of the original hybrids.
Fact: Although Cannabis researchers at "Ole Miss" assembled a world class Cannabis collection during the late 1960s and
early 1970s, there is no evidence that these researchers were ever involved in breeding high quality marijuana.[1]
The standard drug strain that is available to qualified researchers in the U.S.A. was originally from Mexico.
Fiction: Apocryphally, G-13 contains 28% THC by weight, about double the average percentage in most high-grade sinsemilla grown
commercially. It has been claimed that some strains of marijuana grown in Amsterdam have met or surpassed this percentage,
but accurate, verified results have not been produced. Also, no other species of the plant seems to have quite the consistancy
of such high THC content.
Fact: Cannabis researchers identify G-13 as an Afghani "indica" (or 'Afghanica') cultivar, high in THC (though not as high as
the 'apocryphal' estimate above).
Reports of THC/cannabinoid content exceeding 20% are invariably from sellers of Cannabis or Cannabis seeds, or from anti-Cannabis
crusaders.
Reliable testing has placed the most potent examples of Cannabis plant matter ever tested at around 18% or 19%
(based on Dutch government testing of medicinal grade Cannabis)
Unsubstantiated Rumors: Allegedly, a single cutting of this potent strain was "liberated" from the government facility in
Mississippi. Other rumors say G-13 was developed by the university of Washington Cannabis testing facility for medical testing
during the 1970s, but this too has not been verified.
In the early 90's, the name G-13 was said to have come from the number of [backcross] generations it took to produce an almost
perfect plant - however, this view has absolutely no basis in reality.
The name G-13 is was derived from the term Government Marijuana, the 13 used as M is the thirteenth letter of the alphabet.
The most common story about the naming of G-13 is that it was stolen from 'grow-room 13' and simply retained its lab ID code.
Another fantasy-based rumour is that the name 'G-13' derives from the 'genotype' having been created to express 'the 13 most
desirable qualities'. Again, this is just idle (and poorly thought out) rumour.
Some seed banks (which are very unlikely to have genetic material from the original clone) describe this strain as the highest
THC content ever. Other seed banks that are known to have actually worked with the clone since the mid-Eighties describe it as
one of the strongest "indicas" ever discovered.
good shyt.
