Crystal Coma is a sativa dominant strain with a 30:70 indica/sativa ratio. What is really interesting about the strain is that it creates a spectacular 27% THC content, which is quite unusual considering its heritage. Crystal Coma is a cross between Skunk and Cheese and is incredibly potent. Keeping this in mind, it is not for the faint of heart. The strain is known for giving experienced users a run for their money at the same time.
