Blimburn Seeds runs this as a sativa feminized line — 20-25% THC lab range, fruity/citrus-dominant terps, 8-10 weeks from flip.

Blimburn Seeds lists this at $25.98 — the lowest base price in the comparison ($30.01 floor). Pack options: 3-seed at $25.98, 5-seed at $36.20, plus larger sizes.

Smell-first: crack a jar of this Blimburn feminized and the citrus hits before anything else—bright orange peel layered under something earthier, almost forest-floor damp. That profile carries straight through to the smoke. Blue Haze sits at 20–25% THC, which is high enough to matter but not so aggressive that it punishes a moderate-skill grower trying to dial in their first serious sativa run. Indoors, expect 400–500g/m² after an 8–10 week flower cycle; outdoors it's equally at home as long as you give it vertical room—this is not a compact plant. The head effect leans cerebral and active rather than couch-heavy, which makes timing your harvest window important: pull too late and that clarity softens into something slower.

Best suited for growers who've already handled a photoperiod feminized strain and want to step up to a longer-flowering sativa without the finicky temperament some pure sativas carry.

Genetics & Lineage

Blue Haze traces its genetics to Blue 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

Blue 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 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 8-10 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

Blue Haze features a fruity, citrus, earthy, pine 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 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.
