Runtz Auto is a feminised autoflowering cultivar that blends the famous Runtz profile with ruderalis genetics, so it moves into flower by itself rather than on a changing light schedule. Its parentage is Zkittlez crossed with Gelato, and the mix is around seventy per cent indica. Plants stay short and sturdy, building a rounded frame with one dominant top cola and denser flowers lower down. Indoors they typically finish between 25 and 80 centimetres tall, with yields quoted at 250 to 325 grams per square metre, and outdoor plants reach a similar, slightly larger scale. The blooms display lime and violet shades with orange hairs, and as they mature the aroma turns sweet and fruity with candy notes. On the palate expect tropical fruit and sugary sweetness, a creamy backdrop and a gentle herbal finish. The high starts bright and uplifting before settling into a calm, body-focused feeling. It is a popular pick for those new to growing, though the scent is pronounced toward the end of flowering.
