Mendocino Farms runs this as a indica feminized line — 20% THC lab range, earthy/sweet-dominant terps, 8-9 weeks from flip.

Lineage: Mendo Breath × Headband × Trainwreck, sourced from Mendocino Farms' NorCal mountain program. That cross leans heavily indica (75%) and shows it — plants stay compact, finish in 8 to 9 weeks, and don't ask much from the grower, whether you're running them under lights or putting them outside in a Canadian summer with unpredictable September weather.

At 20% THC the effects lean toward evening use: relaxed, gradually heavy, with earthy and sweet notes that sit clean on the palate without sharp chemical edges. Indoor growers running optimized canopy technique are reporting returns near 600 g/m², which is a strong number for a strain rated easy difficulty. The feminized format means no time wasted culling males. Good fit for first-time outdoor growers in shorter-season regions like the Prairies or interior BC, where an 8-week flower window gives you a comfortable buffer before the first hard frost.

Genetics & Lineage

Ace of Spades traces its genetics to 25% Sativa/75% Indica (Mendocino Farms). 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 Mendocino Farms, 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 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Ace of Spades delivers THC levels of 20%, 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 Ace of Spades

Ace of Spades 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 600g/m2. Plants typically reach 100-160cm 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 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Ace of Spades 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, Ace of Spades 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 Ace of Spades?

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.
