Lineage: Haze × Sensi Amnesia × Trainwreck, all three parents visible in the finished flower. California Haze Feminized runs 10–14 weeks — long even by sativa standards — but growers who stick with the schedule regularly pull 500–700g/m² under good light. THC tests between 18–24%, with the upper range showing up most often in warm, Mediterranean-style conditions where the plant gets the heat and sun it wants. The structure is open and tall, with internodal spacing that makes canopy management easier than most full sativas; LST and a single topping are usually enough.

Flavor sits at a citrus-and-diesel crossroads with a sweet back note that softens the gas. The head effect is alert and stimulating rather than sedating — functional daytime territory. Works indoors or out, but outdoor runs in warm climates give it the most room to reach its ceiling.

Best suited to patient growers comfortable with longer flowering windows who want a true sativa character without fighting a difficult plant.

Genetics & Lineage

California Haze traces its genetics to California Haze (Sensi Seeds 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 Sensi Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily energetic 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 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

California Haze delivers THC levels of 18-24%, 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 California Haze

California 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 10-14 weeks with yields of 500-700g/m². Plants typically reach 100-180cm 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

California Haze features a citrus, diesel, sweet, earthy terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. 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, California 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 California 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.
