The shortest version: Coastal Genetics's take on hybrid genetics, 21% THC, 8-9 weeks flowering, moderate grow.

Smell-first impressions from this one lean citrus-forward with a clean sweetness that rounds out into something earthy on the dry. Coastal Genetics built it around cookie, cake, and Runtz lineages — kept proprietary, but the terpene fingerprint is recognizable to anyone who's grown that family tree before. At 21% THC and an 8–9 week flower cycle, it moves fast for a strain with this much going on aromatically.

Yields land around 450g/m² indoors under reasonable conditions, and the mold resistance makes outdoor and greenhouse runs genuinely viable — not just technically possible. Difficulty sits at moderate, so first-time auto growers may hit a learning curve dialing in feeding, but anyone with a couple of runs behind them should feel comfortable. Best suited for growers in humid coastal climates who've lost harvests to mold before and want a fast-finishing auto that won't fold under that pressure.

Genetics & Lineage

Frosty Auto traces its genetics to Proprietary cross (Coastal 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 Coastal Genetics, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric 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 21%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Frosty Auto delivers THC levels of 21%, 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 Frosty Auto

Frosty Auto is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 450g/m2. Plants typically reach 100-160cm 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

Frosty Auto features a citrus, earthy, sweet 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, Frosty 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.
