Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10 weeks. Great for new growers, small spaces, or multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

G13 Strain Origin

G13 is the stuff of legends. According to marijuana folklore, this potent cannabis was an experimental blend of everything the United States Government could get their hands on in the 1960s. Working in complete secrecy, government researchers tested the boundaries of marijuana's potential. They created multiple cannabis plants with various THC content as a way of testing the popular drug.

As the legend goes, samples from the study eventually made it to the public thanks to a rogue government employee. After sneaking some cuttings of the cannabis plants out of a university laboratory, an expert grower nursed the cuttings, selecting the sample with the best results.  Eventually, they produced 'government 13'.

For years, g13 was only available as a clone. However, the demand for g13 strain seeds never slowed down, until someone eventually bred feminized seeds. Finally, everyone can grow this historic strain. We are proud to offer g13 seeds for sale.

What is the G13 Strain?  

G13 is a surprisingly happy indica with a strong body high. In terms of effects, it behaves somewhat like a sativa, but it is genetically indica or indica dominant. For years, g13 marijuana seeds were nearly impossible to find. The cannabis strain started as a clone, and continued as a clone for many decades.

G13 cannabis grows well in cooler environments and boasts a high yield. THC content levels tend to be moderately high (averaging around 19%), but the effects are stronger than the numbers suggest. Some of the best genetics contain a g13 THC level of 24%. This will certainly slow anyone down.

Because G13 began as a clone, plenty of research has gone into developing G13 cannabis seeds. Growing this strain tends to be moderately difficult. However, most people have better results when growing from seed, and G13 is highly resistant to most diseases.  

Growing G13 Feminized Seeds  

G13 marijuana plants are moderately difficult to grow. Many people choose hydroponic growing for G13 because it tends to prefer lots of nutrients. Hydroponic growing makes it easy to precisely control nutrient uptake.

Regardless of your growing method, you should prune G13 plants. They are very bushy plant that may develop mold or rot if not given enough airflow. A sea of green method can improve airflow and yield, although it already tends to produce plenty of buds. It's best to train your plant during the vegetative stage.

In general, a marijuana plant grown from G13 seeds will behave like a clone plant, except that growing from cannabis seeds takes a few weeks longer. The longer lifecycle produces more stable plants that can handle the challenges of the flowering stage. In other words, seed plants tend to produce better weed. Plus,  our cannabis seeds, G13 seeds feminized to prevent fertilization, making potent buds more likely.

Female cannabis plants, contrary to male plants, are the ones that actually produce weed. They follow a strict light cycle and start flowering when they receive less light per day, i.e., in the Fall or when you manipulate the light cycle indoors.

We advise also reading our germination instructions for guaranteed results.

Preferred Climate

The most important consideration when growing this cannabis strain is moisture. Keep G13 in a dry and sunny climate if growing outdoors. Ideal growing temperatures are between 65- and 85-degrees Fahrenheit.

Feeding G13 Plants

G13 plants respond well to extra nutrients. Visit our nutrient section for the right plant food for every grow stage.

We recommend giving your plants:

Flowering & Yield

G13 plants flower in 9-11weeks or late Fall if growing outdoors. Grow from cannabis seeds indoors in less than 12 weeks. Your harvest will be large, both indoors and outdoors. Indoor growers can expect yields of up to 21 oz /m2, while a single plant can reach 40oz.

Experiencing the G13 Strain

G13 is the indica that behaves like a hybrid. You'll feel relaxed and sleepy like most indica strains, but you'll also feel happy and perhaps euphoric at the same time. It's what you'd expect from a pure hybrid, except the effect is definitely indica. You're perfectly fine taking this strain before bed or while socializing with friends. Just remember to have some caffeine nearby if you intend to stay awake. G13 is a nighttime strain that helps people relax or deeply settle into calming activities, such as painting. For some, the effect is clearly psychedelic, while others experience a sense of relief. It's a complex marijuana strain that doesn't quite fit in a box.

While sleepy and happy are your most likely feelings, there's a good chance you'll also develop a dry mouth and eyes. If this happens, keep some water around. Unlike typical indica strains, most people do not experience hunger. There may, however, be some dizziness or paranoia, and that's possibly a sign it's time to sleep.

G13 Smell and Taste

This strain could be described as loud. The pungent, skunky notes make it clear that G13 is a potent indica. The smell begins during the flowering phase, which is one reason some people choose to grow it outdoors. However, it also has sweet aromas that reveal its surprising effects.

The taste further adds to the mysteriousness of this strain. The skunky scent becomes a savory mixture of pine and earth that is (strangely) delightful.  

Uses for G13

If you suffer from chronic sadness and an inability to sleep, G13 is the perfect strain. It excels at improving moods and relaxing the mind. Whether it's a few puffs as a stress reliever or regular use to calm chronic tension, G13 is a powerful weed for a better state of mind.

This strain is also a potent, high THC strain with an intense body high. It may be one of the best strains for feeling free, having a great time, and promptly falling asleep. It's popular for every one of these reasons. Therapeutically, people use it to reduce pain, fall asleep, and ease anxious thoughts.
