Seb's take
A direct autoflowering descendant of Critical Mass, with a high-CBD parent and Ruderalis added for speed and stability. Pungent and fruity up front, woody on the exhale, earthy on the finish; the effect is snug and comfortably relaxed, popular among insomniacs and those nursing minor aches.
Where it comes from
A direct autoflowering descendant of the photoperiod Critical Mass, with two further branches on the family tree: a high-CBD variety, and a Ruderalis that lent the stability and the automatic habit. Herbies Seeds assembled the three into an indica-leaning plant — sixty-five percent — that keeps THC modest at six percent while pushing CBD to eleven. The Critical Mass character comes through clearly; the additions simply steady and soften it.
Nose & flavour
The terpene profile is pure Critical Mass, which is to say pungent and fruity the moment you grind the buds. Woodier notes arrive on the exhale, subtler than the fruit that precedes them, and an earthiness lingers on the palate afterward. A full, rounded nose that carries the parent's signature faithfully — loud up front, contemplative on the finish.
The high
A snug, comfortable sort of relaxation, settling over mind and body after a puff or two. Nothing sharp or demanding about it — the low THC and generous CBD see to that — just an even, easy calm. The kind of experience that asks nothing of you and leaves you content to be still.
Growing it
Flowering runs sixty-three to seventy days, a middling schedule that suits its standard pace. She reaches around a hundred and fifty centimetres, a fair height, so a little planning for space is wise. Yields sit between 336 and 397g per square metre — solid rather than spectacular, but consistent, and in keeping with a CBD-rich plant that prioritises balance over sheer bulk. A steady, unfussy grow that behaves much as its Critical Mass parent would lead you to expect.
