Sour Diesel x Dirty Taxi is a cannabis strain cross, often known as "Northeast Taxi" or "Sour Taxi," blending the classic uplifting, diesel-pungent Sour Diesel with the complex, earthy, and gassy notes of Dirty Taxi (a GMO x Chem D I95 cross), resulting in a powerful, sativa-leaning hybrid known for its strong aroma and euphoric, relaxing effects.
