Seb's take
Jack Herer joins the Cinderella 99 line here, backed by Magnum Auto genetics, for an 80% sativa autoflower that still reaches a genuine 150cm. Sweet, tropical fruit on the nose; the high rises clear and uplifting before a relaxed hybrid finish. Give her the headroom despite the autoflower badge.
Where it comes from
World Wide Cultivars folded Jack Herer into the Cinderella 99 line and backed the whole thing with Magnum Auto genetics, giving an 80% sativa that flowers automatically without giving up its character. The lineage is a strong one, Jack Herer and Cindy 99 being two of the more decorated names in the book, and the Magnum Auto simply makes the schedule its own. A pedigreed autoflower rather than a convenient shortcut.
Nose & flavour
Fruity and tropical, with a sweetness shaping the finish, the sort of nose that leans toward the fruit bowl rather than anything sharp or fuel-like. It is bright and inviting, and it carries cleanly through to the smoke. A pleasant, uncomplicated profile that suits the daytime disposition of the plant.
The high
It opens clear and uplifting, a proper mental rise, before settling into a smoother hybrid rhythm and a relaxed finish. Strong yet active, in the record's phrasing, which is a fair description of an 80% sativa carrying 24 to 26% THC. Good company for a busy head, with just enough of a settle at the back to keep it civil.
Growing it
An autoflowering feminized plant at 24 to 26% THC, with a listed 1.0% CBD alongside. Flowering runs 70 to 84 days from the record, on the longer side for an auto, so patience is the price of the potency. Height reaches around 150cm, a genuinely tall sativa structure that the autoflower badge does not tame, so give her the headroom despite it. Yields land at 488 to 610 g/m². A strong, upright plant that behaves more like a photoperiod sativa than its format suggests.
