Advanced Genetics runs this as a hybrid feminized line — 20% THC lab range, earthy/sweet-dominant terps, 8-9 weeks from flip.

Advanced Genetics lists this at $30.59 — above the median of $30.01 across 4 listings. Pack options: 3-seed at $30.59, 5-seed at $44.99, plus larger sizes.

Smell-first: crack a jar of Blue Haze and you get that familiar damp-earth note under a layer of soft sweetness — nothing loud, nothing synthetic, just clean and grounded. Advanced Genetics built this feminized strain to pull 500g/m² in an 8–9 week flower cycle, and the numbers hold up whether you're running it indoors under LEDs or finishing it outside in a long warm fall. At 20% THC, the effect lands firmly without punishing newer users, which lines up with the moderate difficulty rating — this isn't a beginner's first grow, but it's not a nightmare either.

The structure stays manageable, canopy control is straightforward, and the earthy-sweet profile comes through cleanly at cure without demanding any special drying tricks. If you've got one or two successful runs behind you and want a reliable producer with decent potency and a flavor profile that doesn't need embellishment, this one earns its tent space.

Genetics & Lineage

Blue Haze traces its genetics to Proprietary cross (Advanced Genetics). This hybrid-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Advanced 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 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Blue Haze delivers THC levels of 20%, 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 Blue Haze

Blue Haze 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 500g/m2. Plants typically reach 100-160cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Blue Haze features a 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, Blue Haze 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 Blue Haze?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
