The record · 3 sections

Embark on a sensory journey with Grateful Chem, born from the potent union of CBD Chem Dawg's pungent diesel fuel notes and Grape Stomper OG's luscious wine grape sweetness.

This balanced hybrid inherits the Chem Dawg's tart, fruity undertones, beautifully complemented by the Grape Stomper's deep, rich wine grape flavors.

Caryophyllene, myrcene, and limonene terpenes converge to create a captivating aroma.

Buds are densely packed with a generous resin coating, reflecting the strain's robust yield.
