Lineage: the Sensi Seeds classic rebuilt around a ruderalis backbone, so the auto version keeps that sharp pine-and-earth nose without needing a light-schedule change to trigger flower. What you actually get in the tent or garden is a sativa-leaning plant that finishes in roughly 8–10 weeks from seed and can push 450–600 g/m² under decent light — numbers that hold up even when conditions aren't perfect. THC tests have come back in the 23–28% range, which sits well above the title's conservative 15–20% claim, so don't underestimate it on the first pull. The dominant taste is resinous pine over dry earth — nothing tropical, nothing candy — and the effect leans clear-headed rather than couch-lock. Difficulty is rated easy, and that tracks: the auto genetics handle minor watering inconsistencies without much complaint, indoors or out.

Best suited to newer growers who want a proven sativa-style buzz without the hassle of a 12/12 flip.
