I just stumbled onto this on the Cali Connection website. I noticed he mentions dogweed from CB.
Chem4 OG (Chem#4 X SFV OGK F4) - The Chem 4 clone was found from seeds started in 2006 from the original seed stock chemdog sent joebrand. joebrand stated the seeds chem sent him and out of them there was chem 1,2,3,4. the Chem 4 is what joebrand dubbed the Reunion pheno as it reminded him most of the original dogweed from crested butte. i crossed this to my SFV OGK F4 amle in hope of bumping up the yeild on the og, and in hopes of bringing a little more citrus out of the chem4. expect large yeilds form this hybrid. Flower time will be 8 weeks
