Cartridge: 510 Thread // Strain: Watermelon Zkittlez, also known as "Watermelon Z," is an indica-dominant hybrid marijuana strain made by a cross of the hugely popular Zkittlez and Watermelon. It offers a wonderful fruity aroma and flavor profile that is mouthwateringly scrumptious. Its high may set in quick, delivering a powerful, head-rushing euphoria. With its heavy effects, Watermelon Zkittlez is best reserved for the end of the day.
