Skywalker OG Runtz XL Auto is Sweet Seeds’ autoflowering version of Skywalker OG (OG Kush x Skywalker), a mainly indica, high-yielding favorite of the American West Coast. The autoflowering genes come from the breeder’s Runtz XL Auto (SWS88), and the result is a seventh-generation auto with very productive, resinous and aromatic plants.
Plants grow to 60–120 cm (24–47 in), finish about 8 weeks from germination and yield 450–600 g/m² (1.47–1.97 oz/ft²) indoors. Heavy resin makes it a natural fit for extraction.
With 18–21% THC, the effect combines creative stimulation with a relaxed body feel.
Lineage: Skywalker OG x Runtz XL Auto
Skywalker OG brings OG Kush character, indica structure and strong performance. Runtz XL Auto contributes the automatic trait and its own pedigree: Runtz (Z x Gelato) crossed with Sweet Gelato Auto (SWS76). Together they give an OG-style auto with a sweeter candy undertone.
The data sheet lists 63.5% indica, 36.3% sativa and only 0.2% ruderalis, one of the lowest ruderalis shares in the Sweet Seeds range.
Aroma, Flavor and Effect
The aroma is intense: sweet, fruity tones up front, then earthy, spicy layers with a distinctive blue cypress note. It recalls the Diesel and OG Kush families, but with a sweeter undertone that keeps it approachable. The flavor is rich and lingering, sweet on the inhale and earthy-spicy on the exhale.
The effect opens with a creative, stimulating lift and gradually brings in body relaxation, a balanced hybrid feel for afternoons or evenings.
Growing Skywalker OG Runtz XL Auto Indoors and Outdoors
Indoors, keep 18/6 or 20/4 light from germination to harvest; it flowers automatically, so there is no 12/12 phase. A 15 L (4 gal) final pot suits its XL size, and LST from week 2–3 helps spread the indica branches for more even buds. Use carbon filtration for the strong aroma.
Outdoors, choose full sun and a fertile, well-drained soil. Each plant can produce 65–200 g/plant (2.3–7.1 oz/plant) in about 8 weeks from germination, with room for repeat sowings in long seasons.
Dense indica buds need steady airflow late in flowering. Harvesting with plenty of cloudy trichomes preserves the creative side of the effect and maximizes resin quality for hash or rosin.
