The specs in one line: 18-25% THC, <1% CBD, 9-11 weeks total flowering, 300-450g/m² reported. Best indoor or outdoor. easy grow.

Smell-first, this one leans into ripe berry with a grounding layer of damp earth — not the sharp citrus profile you see on half the autos in this price range. Fastberry Auto runs 9 to 11 weeks seed to harvest, which makes it a practical choice for Canadian outdoor growers trying to squeeze a late-season run before October temperatures drop. Indoors, expect somewhere in the 300–450 g/m² window; that upper range is realistic under a dialled 600W setup with decent VPD control, not a given for a first-time grow. THC comes in between 18 and 25%, so the spread is wide enough that curing time and environment genuinely affect your end result — rush the dry and you'll land at the low end.

Seedsman rates this as an easy grow, and the autoflower format means no light-schedule management, which removes one variable for newer cultivators. A solid pick if you're working a short outdoor season or a small tent with limited space.
