Spec sheet first — strain: sativa, seed type: feminized, THC: 17-22%, yield band: medium, environment: indoor or outdoor.

Smell-first: crack a cured jar and the room shifts — bright citrus up front, then a slow drift of damp earth underneath. That combination comes from a sativa-leaning line that Seed Supreme has kept consistent across runs, and it shows in the numbers. Indoor growers working a controlled tent can reasonably expect 400–550 g/m² after an 8–10 week flower, which sits comfortably within reach for someone past their first grow but not yet dialling in a commercial setup. THC typically tests between 17–22%, so the effect has real weight without being a one-hit novelty. The plant handles both indoor and outdoor environments, which makes it a workable option for Canadian growers who want flexibility between a summer patio run and a year-round indoor cycle. Moderate difficulty means you'll want some experience managing stretch on a sativa structure, but nothing that requires advanced training techniques.

Best suited to intermediate growers who want a straightforward sativa-leaning plant with reliable yields and a clean citrus-earth flavour profile.

Genetics & Lineage

Blue Haze traces its genetics to Blue Haze Feminized (Seed Supreme genetics). 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 Seed Supreme, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily energetic and creative effects, making this strain perfect for daytime use, creative projects, and staying productive. The cerebral lift arrives quickly, sharpening focus and inspiring motivation. With THC levels reaching 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Blue Haze delivers THC levels of 17-22%, 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 400-550 g/m². Plants typically reach 80-150 cm 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 citrus, earthy 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, Blue Haze is commonly reported to help with depression, fatigue, lack of motivation, and ADHD symptoms. The uplifting, focusing effects make it popular among medical users seeking daytime functionality. 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?
