Origins, Genetics, History

G13 pot is a strain of mysterious origin and history. G13 is rumored to be a virtual Franken-weed, engineered by government scientists from the CIA and FBI working together to make the most powerful weed conceivable. Apparently, G13 was the product of this experimentation, an Indica dominant hybrid, engineered from an unknown Afghan. Legend has it that a lab technician thought this weed was too good to leave in the hands of government scientists who would likely abandon it should it prove useless as a weapon or for other nefarious purposes. So, he took a small sample from the lab, and released this powerful weed upon the earth. Growers quickly took to it as it proved to be a powerful Indica for medical or recreational purposes. G13 is known for its ability to produce a whole-body numbing effect without inducing fatigue. This results in a very clean high.

Appearance and Smell

G13 is light green with prominent orange pistils throughout. It is very dense and smells fruity, citrusy, and sweet, like mandarin oranges. G13 has a pungent, fruity smell which is earthy and sweet. One puff and you will taste the dank and fruity flavors which are yet clean and go straight to the brain.

How to Grow G13 Cannabis Seeds and Cuttings

Growing weed from G13 cannabis seeds and cuttings is of moderate difficulty.

Outdoors, G13 will grow in a warm and dry environment but is also tolerant of higher temperatures. Tying, staking, and trimming may be required if you grow these plants to a larger size. Harvest is around the end of October. G13 plants will yield 40 ounces per plant outside. This high yield with the intense potency of the plant makes it a favorite.

Indoors, you can expect a yield of 21 ounces per plant.               These plants provide abundant yield. Flowering takes 10 to 11 weeks. This long flowering period also adds to the rumors of scientific engineering gone into the creation of this Franken-weed strain, G13.

Medicinal Marijuana Review

G13 weed has high-moderate THC levels, from 22% to 24%. Although it is the consummate recreational strain, it has the strength and balance to hold its own as a medicinal strain.

G13 has a powerful ability to blanket the body in pain relief, warmth, and comfort, without at the same time making one tired and fatigued. This makes it perfect for chronic pain, pain associated with treatments like those for cancer, back pain, fibromyalgia, shingles, and other painful chronic conditions.

G13’s mood-boosting effects are also powerful, making it useful for mood disorders. While more stimulating strains may aggravate anxious symptoms, G13’s powerful Indica effects can soothe anxiety and depression.

G13’s numbing effects also numb the gag reflex, making it an excellent choice for nausea associated with various conditions.

G13 is also a powerful antidote for everyday stress. It may even give the immune system a boost.

Sorry but for a strain that has a majority of indica and a higher % of THC. This weed sucks. The buzz is real mellow, actually gives me an upper and it doesn't relieve any pain at all. I bought an Oz and now i have to mix it woth other strain to get through it. Takes about 5 joints to actually feel high. Althought it's perfect for anyone who's not a daioy smoker.

G13 strain is great, it definitely cures all the stress you have. The high is very intense and strong. It peaks for 45 minutes then settles down to a very wonderful very satisfied state of euphoria. Muscles just seemed to relax and brought about slight head high. Gave me much energy and I was very talkative and giddy. This strain has been essential in maintaining a healthier lifestyle for myself.

 by Sam

I am in love with this intense indica. Good taste, rich aroma contains heavy body high and uplifting effect. A great strain if you struggle to sleep at night, a joint before bed works like magic. However, when you smoke too much, it because quite overbearing. Outstanding in every way! Do yourself a favor and try this strain. Very powerful. Recommended by all means.

 by Penelope

This weed has given me a lot of happiness. Every time I smoke it, I want to hang out, talk with people, and just enjoy myself. The dispensary guy told me that I should expect to be in the state of total euphoria that leads to a relaxing head high, and this was exactly what happened. I was quite impressed with its potency because it made me extremely sleepy. A good time plus a heavenly sleep – what could be better?

 by Ethan

Oh man. This is some weed. I smoked it twice several days ago and thought it was going to be a nice relaxing night but never expected it to be that relaxing! I mean I couldn’t remember how I got to the bed or what I had for dinner. Long story short, the experience was unbelievable. If you’re a fan of heavy Indica just like I am, you should definitely try this stuff, man.

The reason why I’m writing this G13 review is that it’s the only strain that almost doesn’t give me any significant side effects. Seriously, I had a slightly dry mouth a couple of times and that’s it. No headaches, paranoia, dizziness, dry eyes or any other effects that my most of my friends have when smoking weed. Coupled with amazing relaxation effects, this makes G13 my favorite marijuana, period.

 by Hannah

Absolutely amazing! G13 marijuana helped me to discover the meaning of life or do many others serious things just after a few sessions 🙂 Although my memories of the smoking and vaping experience with this weed are fairly limited, I can tell you for sure: this stuff gives me an incredible high and good 8 hours of sleeping like a baby.

 by Joseph

I’ve been having problems with appetite recently due to my condition and drank mostly water throughout the day. When I couldn’t take it any more I went to the dispensary that opened near the local gas station and bought G13 strain. The effects were actually pretty interesting. I felt quite relaxed and indifferent to everything for a couple of hours and when the effects ended, I took my van and drove to KFC. I got 10-piece chicken and ate everything in like 5 minutes! Thanks G13

 by Addison

Love the wonderful smell of G13 cannabis. The head high is very smooth but a bit strong for me. I swear I could feel something tugging on my ears when I was smoking this with a friend of mine. Thankfully, the tugging lasted for like 20 minutes and then I was completely locked to the couch for two and a half hours. Great smoke.
