Our take
Cannatonic is a feminized, indica-dominant strain from Resin Seeds, bred by crossing MK Ultra with G13 Haze. Its standout trait is an unusually balanced cannabinoid profile — roughly 10% THC alongside 10% CBD — which makes it a natural choice for growers who want something outside the high-THC mainstream. Beginner-friendly and adaptable, it suits first-time photoperiod growers without demanding much.

Target yields reach up to 510 g/m² indoors when given consistent light and basic care.
