Type: Sativa/Indica (depends on whom you ask)
Genetics: Unknown (most likely Afghani)
The G-13 cannabis strain could be either an indica or a sativa depending on who you talk to, and that is just the tip of the iceberg as far as could-be's and what-if's concerning this legendary strain. What we can gather is that either way this strain is extremely potent and has become the main character in many forms of cannabis and urban legends.
There are lots of stories out there, but my personal favorite is that the CIA and FBI gathered some of the best possible strains from around the world available to them at the time and housed them at a secret installation at the University of Mississippi. These clones (reportedly mostly Afghani cuts) were then supposedly labeled as G-1 to G-23. Each clone had slightly different characteristics and performed differently as you would expect, and the G-13 cut turned out to be the best of the G 1-23 batch. A female clone was then liberated by one of the facility's research assistants (as the story goes) and it soon spread throughout underground marijuana gardens in the U.S. as well as Europe. At the time during the late '60s and '70s, the G-13 strain was competing with such potent strains as Acapulco Gold, Northern Lights, and Thai Stick, but the reported 20%+ THC content made it stand out amongst these other heavy hitters.
Looks and Smell
This particular batch of G-13 has a color that is a slightly lighter tone of green than most strains I've come across. The nugs' appearance is somewhere between a typical indica and typical sativa structure. Go figure, right? The size is slightly larger than kernals of popcorn, and they were all covered in distinct orange hairs and a generous dusting of trichrome powder. G-13 has a crisp pine smell meshed with a chemical and citrus apple scent. However, once busted open, these fairly frosty buds released a uniquely heavenly smell. The beautiful aroma jumps out at you and is not subtle in the least.
The G-13 high was amazing and energetic, yet possessed a mellow head buzz in unison. The effects were unreal as the potent, thick smoke produced a high that came on almost immediately after smoking and lasted a good 2-3 hours. The taste was hashy, spicy, and suprisingly a bit bland compared to the smell. I'm not saying the taste experience was unpleasant, but I just expected a little more of something to stand out--but nothing to report. Overall, the effects from G-13 are hybrid in nature, I guess you would say, with the energetic body high combined with an almost mind-numbing sensation. These facts lead me to believe that I cannot help end the great G-13 indica/sativa debate. Sorry, guys.
The G-13 strain is reportedly a low-yielding plant, which is why you often see a hybrid cross of the strain but hardly ever the original. In fact some say that a pure G-13 strain is long gone and no longer exists today. However, many popular crosses can be found; one in particular, Mr. Nice (G-13 x Hash Plant), is frequently available these days and is considered by many to be the closest descendant of the original G-13.
G-13 will not lock you hopelessly on your couch, bed, or bean bag chair. The strain has excellent stress and pain-relieving qualities, providing users with a strong body high while simultaneously giving them an uplifting, joyful state. Whether the stories about this strain's origin are true are not, it really does not matter beyond the fact that everyone loves a good marijuana tale. What matters is whether or not you like it. So take the challenge, get your hands on some G-13, and decide for youself: is it an indica or sativa, is it dank or stank?
