Cultivation Details

Old Growth OG grows with a medium structure, producing sturdy, resin-drenched colas in just 8 to 9 weeks of flowering.

Old Growth OG is well-suited for evening use or when you’re ready to unwind with a strong but steady high.

Flavor & Aroma

Old Growth OG is defined by its earthy, woody base paired with a sharp diesel-fuel punch and hints of lemon zest. The inhale is smooth yet bold, coating the palate with piney spice, while the exhale leaves behind a lingering fuel-heavy finish. Its aroma is pungent and unmistakably OG—earth, pine, citrus, and gas woven together into a deep and timeless bouquet.
