Sisters are doing it for themselves! Chemdawg’s sativa-dominant sister is known as Chem’s Sister, or Chem Sis. The phenotype appeared in the late ’90’s and has matured into the long-lasting sativa seen today. Light green buds sprout white hairs that get darker and bolder over time. Uplifting and euphoric, Chem’s Sister boasts citrusy chemical flavors with a recognizable skunky fuel smell.
