Seb's take
Critical Mass, Skunk #1 and Hindu Kush combined into a compact, heavy-yielding Indica-dominant hybrid — barely 70cm tall indoors yet capable of 550g/m². Long, dense, resin-rocked buds on a vigorous frame, fragrant enough that ventilation stops being optional. Does not travel discreetly.
Where it comes from
Vision Seeds combined three heavyweight names — Critical Mass, Skunk #1 and Hindu Kush — into a compact, heavy-yielding indica-dominant hybrid. Each parent pulls its weight: the Critical Mass for volume, the Skunk #1 for pungency, the Hindu Kush for that low, sturdy frame. An 80% indica that carries a great deal of pedigree in a remarkably small package.
Nose & flavour
The record does not list her nose in detail, though it notes plainly that she is very fragrant — fragrant enough that ventilation stops being optional. With Skunk #1 in her makeup the character is unlikely to be shy, but I will keep to what the record confirms: she is loud, and she does not travel discreetly.
The high
Her effects go unrecorded here, so I will not invent them. What the lineage fairly suggests is the settled, weighty character an 80% indica of Kush and Critical Mass descent tends to carry — but that is inheritance, not a confirmed note, and I would rather say so than overstate her.
Growing it
A striking plant on the numbers: barely 70cm tall indoors, yet capable of 550 g/m², with a flowering period of eight to nine weeks — around 56 days. She has a vigorous structure with long, dense, rocky resinous buds, thin leaves and wide node spacing. She is fragrant enough that a carbon filter earns its place indoors, both to keep the peace and keep the secret. Small in stature, heavy in return, and loud throughout.
