How to Grow Acapulco Gold Strain (2026 Grow Diary)
Acapulco Gold is a legendary sativa strain that put Mexican landrace genetics on the global map. With 80% sativa / 20% indica lineage, this classic cultivar offers an energetic, euphoric, and uplifting experience. At up to 18% THC, it’s more about clarity and creativity than overpowering couchlock. Flavor-wise, expect rich coffee, earthy, and fresh wood notes. Tall (70–80 inches), long-flowering (10–11 weeks), and resilient, Acapulco Gold rewards patient growers with sticky, golden-hued buds.
