G13 Marijuana Strain



G13 Marijuana Strain

G13 Marijuana Strain is a very strong strain of cannabis Indica that is the subject of many urban legends. According to some accounts, the CIA, FBI, and other agencies gathered the best strains of marijuana from breeders all over the world. At a super-secret installation at the University of Mississippi, they bred many new super hybrids in the late 1960s. Allegedly, a single cutting of this plant was liberated by an unnamed technician and bred for the masses.

What Is the G13 Strain?

As a best guess, G13 weed is an indica-dominant (70%) hybrid strain. As for its history, it is almost impossible to tell the difference between legitimate story and urban myth. The story of G13 arguably begins at a rural Mississippi research facility sometime between the late 60s and early 70s. According to one account, at least one U.S. Government agency was allegedly developing weed with assistance from the University of Mississippi, which is where government-approved cannabis grows.

The suggestion is that the G-men grew pure Afghani clones labeled from G1 to G23. While every clone had slightly different traits, G13 was allegedly the most stable. Then, a breeder named Neville Schoenmaker contacted an unnamed rebel lab technician who was keen to liberate G13 and received a single sample of this new strain which he spread throughout the United States.

G13 made its way into the mainstream via the smash hit movie, American Beauty, where it was featured as a form of marijuana that doesn’t make you paranoid. In truth, the origins of this strain remain unknown (unless you believe the myth), but we definitely know that it is an exceptionally good smoke.

G13 Aroma

is NOT a strain suited for clandestine users. You can put it in a sealed bag and STILL get a slight skunky whiff! It has a slightly sweet smell with more than a hint of savory cheesiness. Add in a wild berry scent, and you have a pretty unique smelling marijuana strain.

G13 Flavor

Most users enjoy the sweet pine flavor, which helps set it apart from the majority of strains you’ll use in your lifetime. There are also mossy and woody flavors mingled in. When you add in a hint of creaminess, you have yourself a strain worth savoring.

G13 Appearance

When you gather a good sample of G13, you will notice a thick coat of trichomes. Check beneath a high-quality nug, and you will marvel at the layers of trichomes located beneath the calyxes. Conclusion: G13 is a strain designed to help you get VERY high!

Strain Grow Info

strain that excels indoors or outdoors. Consider using the Sea of Green (SOG) training technique if you are intent on growing enormous buds via an indoor weed installation. We recommend leaving lots of space between branches to provide room for these buds to grow, and also to keep good airflow. Consider pruning your G13 crop, but make sure you cut a little at a time or risk sending your plants into shock.

Strain is capable of handling daytime temperatures as low as 65 degrees Fahrenheit, and also thrives when your grow room’s temperature is as high as 85 degrees. When growing outdoors, you’ll benefit from the fact that this strain handles lower daytime temperatures better than most marijuana strains.

Outdoor growers will enjoy higher yields than their indoor counterparts because it flourishes when it has room to branch out. In fact, it grows so tall that you need to support it during the flowering stage. It is a heavy feeder, so make sure it gets lots of Nitrogen, Potassium, and Phosphorus.

Outdoors, G13 marijuana strain is ready for harvest late in the season, at the end of October or even early November. G13 could yield an incredible 40 ounces of bud per plant outdoors which makes it possible to mass-produce it. Indoor growers don’t exactly miss out on yield. Its flowering time is 9-10 weeks, and indoor cultivators could see a yield of up to 21 ounces per square meter planted.

THC Content – Highest Test

Advances in growing technology, coupled with genetic selection, means it is almost becoming ‘normal’ for marijuana strains to contain 25% THC or higher. In the golden age of marijuana, the THC content of weed was around 4% on average, mainly due to the low-quality of weed which normally consisted of stalks and stems.

There has been an increase in strains with an alleged THC content of over 30%. In reality, it is likely that labs are artificially inflating the THC content of strains. We know this because the chemical ceiling is around 30% by dry weight.

In any case, there are lab tests which suggest that G13 has a THC content of up to 24%. Unlike many other strains which have a large THC range, G13 is fairly consistent. The majority of samples will have a THC content of at least 22%.

CBD Content – Highest Test

We now live in an era where there are marijuana plants specifically designed to have a high CBD content. Cannabidiol is known for its potential healing benefits, and unlike THC, you will not experience a psychoactive high. This is why high-CBD, low-THC strains such as Charlotte’s Web are legally available to children with epilepsy.

G13’s CBD content is around 0.25% on average, although you may find samples with 1% CBD. This is not high enough to counter the strain’s psychoactive effects.


It won’t take you long to discover why G13 is considered a ‘super strain.’ You will feel a head high that begins right behind the face. It also relaxes you in quick time and could help relieve you of any stress you’re currently feeling. Users often claim that a few tokes of G13 immediately puts them in a better mood.

G13 is exceedingly potent, so a little goes a long way, especially when you’re a novice. Initially, you should feel energized, but soon, the Indica element kicks in and you feel infinitely more relaxed. Fortunately, G13 does not induce couch lock, but the balanced high could lead to euphoria.

Medical Benefits

G13 is a popular medicinal strain and is often used to treat chronic stress. As it helps to elevate your mood, consider using G13 if you are suffering from depression, anxiety, or any other mood disorder. The potency of this strain also ensures it acts as an analgesic, so if you have an issue such as migraine headaches, joint pains, or muscle spasms, G13 could be the ideal strain for you.

Possible Side Effects

The main issue lies in  potency. If you are a novice user, consuming too much G13 could cause a spike in any anxious or paranoid feelings you already have. In rare cases, this strain has been known to cause mild headaches once the high has worn off. You may also experience cottonmouth, dry eyes and dizziness. This is often due to dehydration, which means drinking water before, during and after using G13 could reduce the risk.
