Beyond the Percentage: Why Terpenes Matter

While THC is the primary engine of potency, terpenes are the steering wheel. Aromatic compounds like Myrcene, Caryophyllene, and Limonene don’t just provide aroma—they shape the high. When these terpenes are paired with high THCa percentages, they create the "Entourage Effect," delivering a more powerful and well-rounded experience than isolated cannabinoids ever could.
