The shortest version: Zamnesia Seeds's take on indica genetics, 18-23% THC, 10-11 weeks flowering, easy grow.

Lineage: GSC × Chemdawg × ruderalis — that cross brings together two heavy-hitting photoperiod parents and wraps them in an autoflowering frame that most beginners can manage without babysitting. The result tests between 18–23% THC, which sits toward the serious end for an auto, and the terpene profile leans into sweet, damp earth — think mushroom funk with a faint cookie sweetness underneath.

Indoors, growers are pulling around 400 g/m² in roughly 10–11 weeks from seed, which makes this a practical pick for a quick Canadian winter grow under artificial light when outdoor season is done. Difficulty is rated easy, so it fits a first or second grow without demanding dialled-in conditions. Best suited to Canadian growers who want a high-THC auto that doesn't require a complicated feeding schedule or a long commitment before harvest.

Genetics & Lineage

GMO Cookies Auto traces its genetics to strains: GSC, Chemdawg, and ruderalis. This indica-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Zamnesia Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

GMO Cookies Auto delivers THC levels of 18-23%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing GMO Cookies Auto

GMO Cookies Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 10-11 weeks with yields of 400 g/m². Plants typically reach 100 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

GMO Cookies Auto features a sweet, earthy terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, GMO Cookies Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow GMO Cookies Auto?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
