Why this one matters: sativa genetics with a 22% THC ceiling and citrus/sweet-led terps. 9-11 weeks flowering, indoor or outdoor.

Smell-first: crack a jar of Silver Haze and the room fills with bright citrus and a clean sweetness that doesn't linger into anything cloying. That scent carries right through to the smoke—light, sharp, no heavy resin funk. At 22% THC from Growers Lab Seeds' proprietary sativa cross, the effect lands energetic and clear-headed without the anxious edge that chases some people away from high-THC sativas. It's a useful distinction if you grow for daytime use or creative work.

Flowering runs 9–11 weeks, which is on the longer side for a feminized sativa, so indoor growers should plan canopy height carefully—this one stretches. Outdoor runs in Canada work in warmer regions if you're starting early under supplemental light. Yield sits around 400 g/m² indoors with consistent feeding and decent light management; nothing technically demanding, but it rewards attention. Best suited to growers who've completed a run or two and want a sativa that actually finishes on schedule.

Genetics & Lineage

Silver Haze traces its genetics to Proprietary cross (Growers Lab 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 Growers Lab 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Silver Haze delivers THC levels of 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 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 400g/m2. Plants typically reach 100-160cm 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 citrus, sweet 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.

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.
