The specs in one line: 18-24% THC, <1% CBD, 11-13 weeks total flowering, 450-600g/m² reported. Best indoor or outdoor. easy grow.

Smell-first: the citrus-diesel combination that made the original Amnesia famous is fully intact here, backed by a fruity top note that lingers longer than you'd expect from an autoflower. Sensi Amnesia XXL Automatic is a sativa-dominant line built from a back-crossed Amnesia crossed into Ruderalis, and the ruderalis influence does exactly what you want — tight internodal spacing, no light-schedule juggling, and a seed-to-harvest window of roughly 11 to 13 weeks regardless of your setup. Under a decent indoor light or a solid Canadian summer, growers are reporting 450–600 g/m², which is a real number for an auto. THC tests consistently between 18 and 24%, so the head effect has genuine weight to it — clear and uplifting rather than sedating, which fits the sativa lean.

The canopy can get dense, so run a light defoliation pass mid-flower to open up airflow and get light onto lower bud sites. Rated easy, grows indoors or out — a solid pick for first-season autoflower growers who don't want to compromise on yield or potency.
