Seb's take
Critical Mass crossed onto an automatic line for a compact, reliable version of the original, well suited to small grow spaces. Earthy and pungent on the nose, skunk and citrus threading through the sweetness; the high is mellow and cerebral, relaxed and happy with a pleasant body buzz beneath. Forgiving of enthusiasm, as autoflowers tend to be.
Where it comes from
Herbies crossed an automatic line onto Critical Mass for a compact, reliable version of the original, sized comfortably for small grow spaces. She expresses her indica-dominant nature both in the growth pattern and in the qualities of the smoke — fast, beginner-friendly, and dependable throughout. A tidy self-timing redraft of a foundation strain, and none of its character lost in the shrinking.
Nose & flavour
Earthy and pungent up front, with a skunk edge and a note of citrus threading through the sweetness beneath. A spicy, woody, piney character to the smoke itself, layered and full. A proper old-school nose — loud, grounded and unmistakably of the Skunk lineage she descends from.
The high
A mellow, cerebral stimulation paired with a pleasant body buzz — the balance indica lovers tend to look for. Relaxed and happy, uplifted at the top and easing toward sleepy at the far end. A gentle, well-rounded high that neither races nor sinks too hard. Comfortable, sociable company.
Growing it
She flowers across 70 to 77 days and stays compact — roughly 70 to 90cm — which makes her a very comfortable size for small setups. The yield runs to roughly 400 g/m². Fast, beginner-friendly and reliable, she is forgiving of enthusiasm in the way good autoflowers tend to be. A dependable, small-footprint version of a classic — the character of the original in a plant that fits the corner of a modest tent.
