What Makes a Focus Strain?
What makes a strain focus is the interaction of cannabinoids and terpenes, not THC alone. Focus strains deliver a clear-headed, task-oriented effect, an effect shaped as much by terpenes like myrcene, limonene, and pinene as by raw potency. Dose matters: most focus effects are strongest at low-to-moderate amounts and shift character as you increase the dose. Start low, especially with unfamiliar genetics, and harvest timing (more amber trichomes = more sedating) lets you tune the final effect.
