Lineage: Pure Haze traces directly back to the old-school Haze family, kept intact by Blimburn Seeds and released in feminized form for growers who want that cerebral sativa character without hunting through a pack of regular seeds. THC sits in the 20–25% range — high enough that inexperienced users should pace themselves — and the flowering window runs 10 to 12 weeks, which is actually tighter than most pure Haze expressions and makes the timeline manageable for a full-season indoor run.

Expect the canopy to stretch, so train early if your ceiling is low. Dried flower carries a citrus-skunk scent with a dry, earthy finish that sharpens on the exhale. Yield potential tops out around 400–500 g/m² under good light, which is solid for a strain this sativa-leaning. Rated moderate difficulty — beginners can manage it, but growers who've handled tall, light-hungry plants before will get more out of it.

Best suited to growers who want a clear-headed, long-lasting effect and don't mind the extra weeks in flower.

Genetics & Lineage

Pure Haze traces its genetics to Pure Haze (Blimburn Seeds). This sativa-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 Blimburn Seeds, 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Pure Haze delivers THC levels of 20-25%, 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, starting as a cerebral buzz that gradually expands.

Growing Pure Haze

Pure 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 10-12 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm 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

Pure Haze features a citrus, skunky, earthy, pine terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. 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, Pure 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 Pure 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.
