This unique hybrid strain is bred by Spanish seed bank Resin Seeds specifically for its low THC content and high CBD content. A cross between a female MK Ultra and a famous G13 Haze male, it produces a relatively short-lived, mellow high that is also uplifting and powerfully relaxing, thanks to the high CBD content. As one of the premier medical strains, Cannatonic is often used to treat pain, muscle spasms, anxiety, migraines, and a wide variety of other physiological and psychological symptoms. Most phenotypes present with a slight earthy odor and a mild, sweet, vaguely citrusy flavor.
