Why this one matters: indica genetics with a 17-22% THC ceiling and sweet/earthy-led terps. 8-10 weeks from seed flowering, indoor or outdoor.

Smell-first: crack a jar of Jack Cookies and you get warm, earthy sweetness that sits somewhere between a baked good and fresh soil — not flashy, just honest and clean. This autoflower runs 8–10 weeks from seed to harvest, which means you can turn a tent around in under three months without touching a light timer. Yields land in the 400–550 g/m² range indoors, and the plant handles beginner mistakes reasonably well — it's been grown successfully in both soil setups and coco without much fuss. THC tests between 17–22%, so the potency is real but not a novelty act. It stays manageable in height, which helps if you're working with a short grow space or running multiple strains in the same room.

Good pick for newer growers who want a solid first autoflower run without chasing something finicky.

Genetics & Lineage

Jack Cookies traces its genetics to Jack Cookies Autoflower (Seed Supreme genetics). 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 Seed Supreme, 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Jack Cookies delivers THC levels of 17-22%, 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 Jack Cookies

Jack Cookies 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 8-10 weeks from seed with yields of 400-550 g/m². Plants typically reach 80-150 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

Jack Cookies 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, Jack Cookies 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 Jack Cookies?

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.
