Meet G13: a legendary name with a rich, resin-coated finish and a deeply relaxing indica lean. Sweet berries, earthy depth, and a crisp pine edge create a bold sensory profile, while its cheerful, sociable lift keeps the experience engaging.

G13 Feminized Seeds pair G13 with a Secret Hybrid for a 70% indica and 30% sativa balance. Its mysterious history is wrapped in cannabis folklore, with tales of a U.S. government-lab origin. Today, this classic’s reputation rests on robust growth, dependable performance, and unmistakable character.

Crack open a G13 bud and discover a forest-fresh blend of earthy, skunky depth and sweet berry notes. Alpha-pinene brings a bright pine lift, while a touch of citrus-like freshness adds sparkle to the aroma. The smoke is smooth, rich, and memorable.

With THC levels ranging from 16% to 21%, G13 offers a potent, indica-leaning experience. Expect a relaxed body, a happier mood, and a talkative, clear-headed lift. It’s a satisfying pick for unwinding in the evening and sharing an easygoing moment with friends.

Myrcene anchors G13’s earthy, musky character and soothing feel. Linalool adds a soft floral note, alpha-pinene sharpens the profile with fresh pine, and valencene contributes a bright citrus accent. This layered terpene mix suits relaxed evenings and social sessions. The strain is also traditionally associated with arthritis, insomnia, and pain relief.

These feminized seeds are designed to produce female plants, and our germination guarantee gives every order added confidence. G13 is beginner-friendly and grows indoors or outdoors in warm conditions. Its compact, sturdy structure and 8–10-week flowering window make it a practical choice for a range of grow spaces.

Give seedlings a quality, well-draining medium such as coco, peat, or a soil blend amended with perlite. Provide steady light, gentle airflow, and appropriate nutrition as plants move from seedling to vegetative growth. Start with a balanced setup, then adjust care to the plant’s development.

G13 grows with a strong central stem and supportive side branches, reaching about 4.92 feet (1.5 m). Maintain clean airflow and keep an eye out for pests throughout the cycle. Indoors, a ScrOG setup can help create an even canopy; outdoors, choose a sunny site with warm, tropical-style conditions and well-draining soil.

Flowering takes around 8–10 weeks. Expect dense, resinous buds with a frosty trichome finish and strong aromatic appeal. Indoor yields can reach 1.47–1.8 oz/ft² (450–550 g/m²), while outdoor plants can produce up to 19.4 oz (550 g) per plant. In the Northern Hemisphere, harvest typically falls in October.
