Why this one matters: hybrid genetics with a 15% THC ceiling and fruity/sweet-led terps. 8-9 weeks flowering, indoor or outdoor.

Smell-first: crack a cured bud and the berry-sweet wave hits before anything else — that Amsterdam blueberry lineage doing exactly what it's supposed to. This 60% sativa-leaning autoflower carries a modest 15% THC, which makes it more functional than flooring, and the fruity sweetness holds through to the exhale without tipping into artificial territory.

On the growing side, expect 300 g/m² after an 8–9 week flower window — reasonable for an auto, though not a set-and-forget variety. Moderate difficulty means it responds well to basic LST and consistent feeding schedules, but it'll punish neglect more than a beginner-friendly auto would. It handles both indoor tents and sheltered outdoor runs, which gives Canadian growers some flexibility during the shorter warm season. Anyone stepping up from their first auto grow and looking to sharpen their technique without committing to a full photoperiod schedule will get a lot out of this one.

Genetics & Lineage

Blueberry Haze Auto traces its genetics to 40% Indica/60% Sativa (Amsterdam Seeds Company). 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 Amsterdam Seeds Company, 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 15%, this provides a mild, approachable experience great for beginners or those seeking gentle relief.

THC Level & Potency

Blueberry Haze Auto delivers THC levels of 15%, placing it in the milder range, making it approachable for newer users or those seeking functional effects. 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 Blueberry Haze Auto

Blueberry Haze 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 300g/m2. Plants typically reach 60-100cm 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

Blueberry Haze Auto features a fruity, sweet 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, Blueberry Haze 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.
