Why this one matters: hybrid genetics with a 18-24% THC ceiling and sweet/earthy-led terps. 10-11 weeks total flowering, indoor or outdoor.

Lineage: Miracle Alien Cookies × Auto Think Different, both Dutch Passion originals — Auto Mac #1 pulls the resin output from MAC and the fast autoflowering structure from Think Different, landing somewhere most beginners don't expect: a genuinely easy grow that doesn't punish minor mistakes.

THC tests typically land between 18–24%, and indoor runs regularly hit 400–500 g/m² without dialing in anything complicated. The 10–11 week total cycle (seed to harvest) makes it a realistic option for Canadian outdoor growers pushing against a shorter season, or anyone running back-to-back indoor rounds. Flavour leans sweet with a grounding earthy finish — nothing sharp or polarising, which suits a wide range of end users. Works in soil, coco, or hydro; handles both indoor tents and sheltered outdoor beds without much fuss.

Best suited to newer autoflower growers who want a reliable first run with above-average returns, or experienced growers looking to fill gaps in a perpetual harvest schedule.

Genetics & Lineage

Auto Mac #1 traces its genetics to Auto Mac #1 (Dutch Passion genetics). This hybrid-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 Dutch Passion, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily euphoric and relaxed 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 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Auto Mac #1 delivers THC levels of 18-24%, 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Auto Mac #1

Auto Mac #1 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 total with yields of 400-500g/m². Plants typically reach 60-120cm 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 45-55% 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

Auto Mac #1 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, Auto Mac #1 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.
