Petro Chem is straight fuel. Heavy diesel, chemical funk and sharp gas dominate the nose, backed by a subtle earthy sweetness that rounds everything out. Crack the buds open and the aroma gets even louder, with that unmistakable garage-and-gas-station funk serious gas lovers look for. This is not a candy strain pretending to be gassy - Petro Chem is unapologetically fuel-forward.
