The shortest version: Premium Cultivars's take on sativa genetics, 25-50% THC, 9-11 weeks flowering, moderate grow.

Lineage: Silver Haze carries the old-school sativa bloodline that shaped indoor growing through the 1990s, and this feminized cut keeps that heritage intact while trimming the finish down to a workable 9–11 weeks. Sweet and floral on the nose with a clean burn, it's a far cry from the fuel-heavy profiles that dominate current catalogs.

Yields land in the 400–500 g/m² range indoors, which is honest output for a sativa-dominant plant without pushing your setup to its limits. The reported THC range runs wide on paper, so expect variance depending on your light intensity, feed schedule, and how long you push the flush. Plants stretch, so growers running low-ceiling tents should top early or train hard. Rated moderate difficulty — manageable for someone past their first grow or two, but not the right starting point if you're still dialing in your environment. Best suited to indoor growers comfortable with canopy management who want a classic sativa profile without a 13-week wait.

Genetics & Lineage

Silver Haze traces its genetics to Silver Haze (Premium Cultivars). 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 Premium Cultivars, 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 50%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Silver Haze delivers THC levels of 25-50%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 Silver Haze

Silver 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 9-11 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

Silver Haze features a sweet, floral terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Silver 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 Silver 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.
