Chem Dawg vs Sour Diesel: Pick One First

First Pick: Sour Diesel

Buy Sour Diesel if you want a daytime smoke. Buy Chem Dawg if you want a shorter flower cycle or a heavier body effect. Both are sativa-dominant hybrids. Both trace back to the same 1991 seed line. The split comes down to terpenes, flower time, and how each one lands.
