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

Smell-first: the dry cure on Blue Haze sits somewhere between damp forest floor and brown sugar—earthy base, sweet finish, nothing sharp or chemical about it. Advanced Genetics built this feminized line around that same approachable character in the grow room: 8–9 weeks to finish, pulling around 500 g/m² indoors when fed and trained properly. At 20% THC with minimal CBD, the effect is noticeable without being disorienting—a workable ceiling for most sessions.

Moderate growers should expect normal Haze stretch in the first few weeks of flower, so top or LST early if canopy space is limited. The strain handles both indoor and outdoor environments, which makes it a reasonable option for Canadian growers who want flexibility across a short outdoor season or a stable tent run year-round. Best suited to someone moving past beginner grows who wants a reliable yield target without chasing a finicky cultivar.

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.
