Effects & Usage



G13 (also known as G-13, for Government Indica Strain 13) is a potent indica-dominant strain, with THC levels ranging from 20 to 27%. This old-school cultivar rose to fame thanks to its interesting origin story, allegedly involving the U.S. Government. In addition, its fans appreciate the powerful feeling of euphoria and deep bodily relaxation this strain induces.


The onset of G-13’s effects is swift, embracing users with a warm, tranquil embrace. Initially, gentle cerebral wave courses through the mind, inspiring a sense of clarity and well-being. Expect a soothing, buzzing head high that will initially make you creative and focused. However, soon after, the indica properties take centre stage. With all the tension and stress blurring away, your body will become profoundly relaxed. You will not be couch-locked, but don’t expect too much energy to work on things. Instead, you will land in a blissful state of deep relaxation and a great mood, focusing on the present moment and savouring it as it is.

Smoked right before bed, this soothing indica can facilitate a great night of restorative sleep. Use it during peaceful evenings or weekends when you want to chill with your favourite book or during movie nights.

If you enjoy the calming, euphoric effects of G13, you may also appreciate the soothing properties of strains like Granddaddy Purple or L.A. Confidential. You may also explore more cannabis varieties to find more strains with similar properties.


G13 is a popular medicinal marijuana strain thanks to the plethora of benefits it provides. This potent anti-inflammatory and pain-killing agent, aided by CBG (at 1%) and pinene, can help in various pain-related conditions. Users report feeling significant relief in migraines, joint pains, arthritis, muscle spasms etc. With the help of uplifting limonene, G-13 is also a feel-good strain that can ease the symptoms of depression and anxiety. Lastly, its calming properties, facilitated by myrcene, will be appreciated by anyone struggling with chronic stress or insomnia.

Side effects

Common side effects of G-13 include dry mouth, dry eyes, and a general sense of dehydration. Paranoia, dizziness and anxiety have been rare, although they can still occur in sensitive users. Remember to be mindful of your limits and start slowly, especially if you are a beginner in the cannabis world.

Due to its sedative properties, G13 should not be smoked early in the day.

Taste & Smell


G13’s sensory profile is nothing short of captivating. Its pungent aroma is a complex blend of cheesy skunkiness mixed with the scent of berries – a scent so potent it will fill any room you are in.

When it comes to the flavour, you will immediately notice a distinct pine taste, setting this strain apart from most you have ever tried. It also has woody and mossy undertones, bringing your mind straight to a forest. This results in a sweet, creamy, pleasurable smoke.

The earthy-green thick buds have an extraordinary amount of calyxes, all completely coated in a thick layer of trichomes, a testament to this powerhouse’s potency.



The exact origins of G13 are shrouded in mystery. However, the most famous urban legend has it that a U.S. government agency developed the strain with the help of the University of Mississippi in the 1960s-70s. The researchers reportedly used pure Afghani indica clones to obtain a super indica strain.

The strain then became mainstream with the help of the American Beauty movie, where it was featured.

Growing conditions

Untypical for most indica-dominant strains, G-13 blooms into very tall plants that require a lot of space. You may need to do some pruning and support the branches to prevent them from breaking under the weight of the heavy buds.

G13 is also one of these rare varieties that will do better when grown outdoors due to needing so much room to flourish. They are also resistant to most diseases and can handle temperature changes very well, which makes outdoor cultivation a breeze.

You will need to wait a little longer to harvest, around 11 weeks, but it will be compensated by astounding yields of 1100 grams per plant outdoors and around 600 grams per square metre indoors.
