Amsterdam Seeds Company runs this as a indica feminized line — 18% THC lab range, earthy/pine-dominant terps, 8-9 weeks from flip.

Smell-first: crack the jar and you get a quiet mix of forest floor, fresh pine, and just enough sweetness to round it off — nothing loud, nothing synthetic, exactly what you'd expect from a well-kept Amsterdam indica lineage. WSU is a feminized strain from Amsterdam Seeds Company sitting at 18% THC, so the effect lands with solid weight without tipping into overwhelming territory.

The grow stats make this an easy recommendation for newer Canadian cultivators: 8–9 weeks to finish, 200 g/m² indoors or out, and a compact frame that won't fight you for vertical space. Works in a tent, a spare room, or a sheltered outdoor spot during a typical Ontario or BC summer. CBD stays under 2%, so the profile skews heavily toward that slower, body-focused indica feel.

Best suited to first-time growers who want a predictable, low-maintenance run with a classic result rather than chasing novelty.

Genetics & Lineage

WSU traces its genetics to Proprietary cross (Amsterdam Seeds Company). This indica-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 Amsterdam Seeds Company, 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 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

WSU delivers THC levels of 18%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing WSU

WSU is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 200g/m2. Plants typically reach 60-100cm 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 40-50% 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

WSU features a earthy, pine, 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, WSU 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 WSU?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
