G13: A Scientific Mystery

G13 seeds grow into medium green plants with long leaves and thick, dense buds. When you harvest this strain you’ll find that the nuggets are orange and green with dusty resin covering them. The buds are sticky, skunky and when broken apart fill your grow room with an inviting cannbis aroma. The medium height plants produce massive yields mixed with a high THC content. While the original G13 strain doesn’t have any big awards to brag about, its offspring have won awards all over the world. If you are interested in growing G13 for yourself you should have some prior experience in the cannabis cultivating world. The plants require lots of attention and a specific environment to produce the kinds of yields the strain is famous for. Following a few simple rules will get you one step closer to harvesting this delicious bud.

Growing Tips for Our Seeds

G13 plants perform best in indoor grow setups but if you live in an area with ample sun, hotter temperatures and lower humidity leading to a dry climate you should be able to grow this strain outdoors to completion. G13 prefers the outdoors because of the fresh air and natural sunlight but if temps drop below 70 degrees routinely you’ll have a hard time bringing this strain to harvest. The plants require enough room to grow laterally because the leaves, branches and roots like to spread out. All of this effort is definitely worth it when you see the monster yields this specific strain can produce.

Dial in Your Growing Conditions

  • Indoor or Outdoor: G13 plants grow well indoors and have the ability to grow well outdoors. The ideal temperature for these plants is a between 70-85 degrees fahrenheit. When it comes to lighting you will want to start with 18-20 hours of light to promote vigorous growth. To induce flowering you will want to dial the light back to mimic natural sunlight and run 12 hours on and 12 hours off.
  •  Moisture control: The G13 strain requires ample humidity levels of around 70% for vegetative stage. Maintain a humidity level of 40% while in the flowering stage. G13 prefers a drier climate to really reach its peak flowering.
  • Training Techniques: Topping and low-stress training can really help with the success of this particular strain. LST and topping encourage a bushier canopy to allow light to reach lower branches and buds.

The Germination Game Plan

Before you even plant your G13 female cannabis plants, you will first need to germinate these seeds. To do so, refer to our free germination guide, knowing that they are backed by our impressive 90% germination guarantee.

Yields, Flowering Time and Harvest

  • Flowering Time: With indoor grows you can expect the G13 strain to harvest after a flowering stage of 70-80 days. Outdoor growers should anticipate harvesting around the end of October to mid-November.
  • Yields: While Indoor yields are around 600 grams per square meter, outdoor grows typically produce up to 1300 grams per plant. These yields make every ounce of blood, sweat and tears you put into this grow worth it.

Dominant Terpenes in G13: What Makes the Myth

The G13 terpene profile is directly responsible for how the plant smells, tastes and the strong effects it has on its users. The most dominant terpene in this strain is caryophyllene, while myrcene and limonene are the secondary terpenes.

  • Caryophyllene: Most Dominant – Tenacious, spicy, and woody, this terpene is also found in clove, black pepper, and rosemary.
  • Myrcene: Secondary Terpene – Features an earthy quality. Present in basil, mangoes, hops and lemongrass.
  • Limonene: Entourage Effect – Sweet, yet has a refreshing citrus bite. Depicting essences of lemon, lime, and grapefruit.

Dominant Cannabinoids in G13:

Cannabinoids play an important role in G13 seeds and are generally a huge part of most cannabis strains. That euphoric, happy and relaxed feeling you get when using the G13 strain is due to its dominant cannabinoids. Each cannabinoid does something different to the user.

  • THC: The Main Character – THC is the most dominant cannabinoid on the molecular level of this strain. The crystalline compound tetrahydrocannabinol is the main ingredient of cannabis. Topping out at a healthy 24%, the THC in the Indica-dominant strain is responsible for the chill and gleeful feeling you get with G13.
  • CBD: Very Minimal Amounts – While the CBD levels in G13 are less than 1% the cannabinoid is still present. CBD plays a smaller role in what the strain does to the user. CBD is non-psychoactive and can produce effects that help with anxiety, sleep and even stress. The CBD in the G13 strain, even in its low amounts definitely has a positive effect on the user.
