Runtz Automatic 3 Seeds by + 1 for free

Runtz Automatic is a 70% indica hybrid that merges the beloved Runtz genetics with indica ruderalis to create an autoflowering version of this iconic strain. Its lineage reads like an all-star lineup: Zkittlez (Skunk × Afghani × Jack Herer) crossed with Gelato (Sunset Sherbet × Girl Scout Cookies).

The result is an extremely compact plant with a distinctive yet manageable aroma and high yields, making it perfect for indoor growers who don’t need maximum discretion. Although autoflowering strains are not ideal for advanced training techniques, their simplicity and reliability make them ideal for beginners or busy growers.

Growth pattern of Runtz Automatic
Runtz Automatic seeds grow into very short plants with tight internodes and robust growth. This compact strain forms a sturdy, bushy structure with a dominant central cola and dense, resinous side buds. As a true autoflower, it begins flowering automatically after a few weeks, with no need to adjust the lighting schedule.

Indoors, Runtz Automatic typically grows 25–80 cm tall and yields 250–325 g/m² over its 60–65 day flowering cycle. Outdoors, plants can reach up to 100 cm and produce around 250 g each.

The buds are chunky, frosty and display lime green and purple hues, accented by bright orange pistils. The large main cola dominates the canopy, while the side branches carry smaller but equally dense buds. Low leaf volume and manageable resin levels make trimming easy.

Because this strain is automatic, growers have limited control over the vegetative phase. Techniques like mainlining or SCROG, which require extended veg, are not suitable. Its delicate branches also make supercropping or lollipopping impractical. SOG is possible, but the unpredictable flowering timing can make it challenging.

Effects, taste, and smell of Runtz Automatic
Near the end of flowering, Runtz Automatic emits an intensely sweet, fruity aroma with tropical candy notes and a touch of earthiness. The smell increases as the plant matures. Growers who need discretion may require odour control.

After curing, the buds develop a smoother, sweet aroma blending tropical fruits, sugary candy and citrus zest. The flavour mirrors this with tropical fruit candy on the inhale, followed by creamy undertones and a slightly herbal exhale — sweet and dessert-like.

Effects begin with an uplifting burst of euphoria and creativity, then gradually settle into a deep, relaxing body stone. This makes Runtz Automatic an excellent choice for unwinding after productivity, eventually melting into the couch.
