Spec sheet first — strain: indica, seed type: autoflower, THC: 18%, yield band: low, environment: indoor or outdoor.

Smell-first, this one announces itself before the jar is fully open — a layered punch of ripe fruit cutting through diesel and skunk that sits in the room long after you've moved on. Blue Zombie Auto from Coastal Genetics finishes in 7–9 weeks from seed, which makes it a practical choice for Canadian growers trying to fit a full outdoor cycle into a compressed summer window, or indoor growers rotating tight schedules. At 18% THC it's not chasing record numbers, but the effect profile leans heavily sedating — the kind of end-of-day stone that earns its keep. Yields land around 250 g/m², which is modest but consistent given the autoflower format.

Moderate difficulty means first-time growers may fumble the feeding schedule; this one responds better to slightly conservative nutrient inputs and stable temperatures in the 22–26°C range. Best suited to growers who've run at least one autoflower cycle and want a reliable evening-use cultivar without a complicated light schedule.

Genetics & Lineage

Blue Zombie Auto traces its genetics to Proprietary cross (Coastal 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 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 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Blue Zombie Auto delivers THC levels of 18%, 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 Blue Zombie Auto

Blue Zombie 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 7-9 weeks with yields of 250g/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 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

Blue Zombie Auto features a fruity, diesel, skunky terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Blue Zombie 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.
