Chem 91

Chem 91, also known as “Chem #91,” “Chemdog 91,” and “Chemdawg 91,” is a hybrid marijuana strain. Much like many other members of the Chemdog line, the origins of Chem #91 are shrouded in mystery. Rumor has it that the lineage was first cultivated by the illustrious East Coast breeder who also goes by the name of Chemdog, and some speculate it descends from a Thai landrace strain. Chem #91 is thought to be an offshoot of the original Chemdog strain, and the numerical addition of “91” is believed to reference the year the strain first came into existence.
