GMO Seeds, also called Garlic Cookies, bring bold flavor, heavy resin, and deeply relaxing effects. This 90% indica-dominant hybrid pairs a soaring euphoric lift with a powerful body unwind. With THC listed at 26–28%, GMO is a standout choice for experienced fans of potent evening strains.

Our breeders created GMO from Chemdawg and Girl Scout Cookies, combining two renowned American lineages. The result is a distinctive, indica-led variety with sturdy growth, dense flowers, and a character all its own.

Expect an unmistakable savory aroma led by pungent garlic and fuel, layered with earthy depth. On the palate, coffee and earth meet fruity sweetness, with a diesel-like edge that lingers after each smooth, rich puff.

GMO delivers a cheerful euphoric lift before settling into deep physical calm. Its long-lasting effects make it well suited to unwinding at night and may appeal to those seeking relief from tension, pain, arthritis, or insomnia. Its intensity calls for a measured approach, especially for newer consumers. Effects vary from person to person.

Nine listed terpenes build GMO’s complex profile: caryophyllene and humulene add peppery, earthy depth; myrcene brings musky richness; and linalool and nerolidol contribute soft floral and woody notes. Alpha- and beta-pinene add a crisp pine accent, while terpinolene and geranyl acetate round out the aroma with herbal and sweet-fruity nuances. GMO’s dense, resin-coated flowers also make it a compelling option for concentrate production.

These feminized photoperiod seeds grow into female plants and flower for around 8–10 weeks. GMO suits indoor and outdoor gardens and is described as beginner-friendly, though its strong aroma and heavy resin production reward attentive care. Germination is guaranteed by Grassfarmer.

Start seeds in a quality, airy medium such as coco, peat, or a well-prepared substrate with perlite. Give seedlings steady warmth and gentle light, then increase nutrients gradually as growth picks up. Indoors, ScrOG training can help create an even canopy and improve light exposure across flowering sites.

Plants can reach about 4.92 ft (1.5 m), with a sturdy main stem and productive side branches. Provide ample light, good airflow, and balanced feeding through each stage. Keep temperatures warm and manage humidity carefully as flowering progresses. Outdoors, choose a sunny spot in a warm climate and protect plants from pests.

After 8–10 weeks of flowering, indoor growers can expect a high yield of around 1.31–1.64 oz/ft² (400–500 g/m²). Outdoors, harvest typically arrives in October, with reported yields of 28.22–42.33 oz per plant (800–1,200 g). The payoff is dense, frosty flower packed with GMO’s unmistakable savory-sweet character.
