Chem 91 is the first plant out of the bag. Of the thirteen seeds Chemdog got at Deer Creek in 1991, this was the one that announced what the whole line would be, and it has been held continuously ever since.

It is the parent most often named in the Sour Diesel accounts, and Swerve put it against SFV OG to make Deadhead OG, a name that points straight back at where the seeds came from.

Everything below carries Chem 91.
