Canadian Sour is an amazing cross between a BC Skunk and Sumo Seeds cup winning Amnesia Ganja Haze. A great tasteful strain. BC Skunk has his heritage in Canada and combined with the Amnesia Ganja Haze makes it a strain with genetics from different parts of the world. Named Canadian Sour because of her Canadian heritage and her slightly sour aroma what she received from the Amnesia Ganja Haze. It's a very stable and uniform strain. Easy to grow and very mold resistant.
