The specs in one line: 18-25% THC, <1% CBD, 8-10 weeks flowering, 400-550g/m² reported. Best indoor or outdoor. moderate grow.

Smell-first: crack a dried bud and you get damp forest floor cut with a thread of sweetness — nothing flashy, just honest earthy-sweet that carries into the smoke. Spanish Moon S1 Feminized is a self-cross of Seedsman's own Spanish Moon line, pushing THC into the 18–25% window while keeping CBD negligible. Indoors, expect 400–550g/m² after an 8–10 week flower cycle — a solid return without demanding expert-level dialing. Difficulty sits at moderate, meaning you'll want some environmental control but you don't need a seasoned hand to finish her clean; she runs well both indoors and out.

Two things stand out here: consistency and straightforward flavor. The self-cross (S1) format means trait expression is tighter than an open cross, so you're less likely to get wildcard phenotypes in a pack. Good pick for intermediate growers who want predictable results and aren't chasing novelty terpene profiles.

THC Level & Potency

Spanish Moon S1 delivers THC levels of 18-25%, 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 with a balanced head-and-body experience that evolves over time.

Growing Spanish Moon S1

Spanish Moon S1 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 400-550g/m². Plants typically reach 100-170cm 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

Spanish Moon S1 features a earthy, 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, Spanish Moon S1 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.
