Smell-first impression on Blue Haze: a sharp citrus peel brightness that settles into damp soil and cedar as the cure progresses. This sativa-leaning feminized variety sits at 17–22% THC, which puts it in a range where effects are noticeable without being disorienting for most experienced users. Indoors, growers working a full 8–10 week flower cycle regularly pull 400–550 g/m² when light penetration is managed well — topping or LST early pays off here given the sativa stretch. Difficulty is moderate, meaning phenotype stability is solid but she'll punish neglect in the watering schedule faster than a forgiving indica would. She adapts to both indoor and outdoor setups, though outdoor runs in warm climates tend to push toward the higher end of that yield window.

Best suited for growers with at least one or two harvests under their belt who want a daytime-oriented strain without chasing extreme THC numbers.

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?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you need a daytime boost for creativity and sustained focus, look no further.
