Cannatonic is unique in that it is the first strain to reach a 1:1 ratio of thc-cbd. Some users prefer it for daytime use or to chill out with at day’s end. This unique hybrid strain was bred by Spanish seed bank Resin Seeds specifically for its low THC content and high CBD content. This was done by crossing a female MK Ultra with a famous G13 Haze male to create one of the premier strains. It has a slightly earthy aroma and a sweet, citrusy flavor.
