The G13 Auto is a marvel of cannabis genetics, the result of a cross between the legendary Afghan G13 and a Ruderalis. This magical blend has produced a mostly indica autoflowering strain that stands out for both its flavor and its potent effects. G13, known for its mysterious origin, conspiracy stories, and links to the FBI and CIA, becomes an even more accessible gem in its autoflowering version.

This is a compact and robust plant that grows with a solid structure, reaching heights between 80 and 120 cm. Its buds are very dense and covered in a shiny resin that gives them an almost lunar appearance, as if sprinkled with crystals. The buds of G13 Auto are a visual symphony of deep greens and some purple hues, standing out among a sea of sparkling trichomes.

Opening a jar of G13 Auto unleashes an explosion of fruity, herbal, and sweet aromas that invade the senses. It’s like a garden of delights with a touch of fresh mint and wildflowers. Smoking this strain is a smooth and pleasant experience, with a smoke that caresses the palate with fruity sweetness and an herbal undertone that lingers in the memory.

With a THC content of 22% to 24%, G13 Auto promises a very potent and long-lasting journey. The initial high is cheerful and talkative, ideal for socializing or just enjoying a good conversation. As the effects settle in, a wave of deep relaxation envelops the body, perfect for unwinding after a long day. It is a strain that invites happiness and tranquility, transforming any moment into a relaxing and pleasant experience.

G13 Auto is not only an option for flavor lovers but also for those seeking therapeutic effects. Terpenes like Borneol and Terpineol add additional properties, helping with insomnia, pain, and arthritis.

Production and Flowering Time

G13 Auto is also a champion in production. Growers, both indoors and outdoors, can expect generous and very high-quality harvests.

Indoors, this autoflowering strain blooms in a record time of 8 to 10 weeks. Under optimal conditions, such as adequate lighting and a controlled environment, G13 Auto can produce between 450 and 500 grams of buds per square meter. By using proper cultivation techniques, such as using quality substrates and maintaining ideal relative humidity, yields can be maximized.

Outdoors, G13 Auto also shows its impressive productive capacity. Planted during the spring and summer months and under optimal conditions, each plant can produce around 100 grams.

How to Grow G13 Auto

G13 Auto strain is a relatively easy strain to grow, perfect for both novice and experienced growers. It is quite resilient and does not require too much specialized attention, although like any other plant, it responds best to proper care.

To achieve the best results, it is important to grow it in a temperate and sunny climate. If growing indoors, we must ensure adequate lighting, preferably with an 18/6 or 20/4 light cycle to maximize production. Outdoors, the plant blooms best when it receives the maximum amount of sunlight possible. It is also crucial to maintain a relative humidity of 55%-60% during the vegetative phase, reducing it to around 40% during flowering, and lowering it further to 30% at harvest time.

G13 Auto is known for its good resistance to pests and diseases, making it an ideal choice for those looking for a robust and easy-to-handle plant. However, we always recommend being attentive to any signs of problems and treating preventively to ensure a healthy and abundant harvest.
