Epsilon F1 Auto is Royal Queen Seeds’ fastest F1 hybrid autoflower. Bred from inbred lines descending from Blue Dream, Blueberry, Amnesia Lemon Haze and Black Domina, it grows with notable uniformity into compact, columnar plants. Indoors it typically reaches 50–70 cm, produces little aroma during bloom, and transitions to flower about 30 days after germination, finishing roughly 60 days from seed. The breeder data sheet lists 30–40 days of flowering. Aromas lean citrus and herbal with earthy, blueberry and lavender notes, while effects are predominantly calming and physically relaxing with a light uplifting edge. RQS classifies potency as very high; reputable retailers place THC in the mid‑teens up to mid‑20s. A good option for discreet grows, small spaces, and short-summer climates.
