Chem3 OG by the The Cali Connection Marijuana Seedbank.
This strain is a cross between the infamous Chemdawg hybrids and the ultimate OG in the cali connections gene pool. The guys explain the cross like this: "Chem #3 is one of the last 4 chemdawg seeds that were planted. Out of the last four, they were all great but Chem #4 was pronounced the keeper. This will be interesting, but the Chem #4 might have a more potent smoke with nuances in the high in comparison to Chem #3. i took the Chem 3 clone only and hit it with my SFV OG f4 male. The offspring are showing great boost in yeild and a more sour note to the lemon pine."
