The shortest version: Blimburn Seeds's take on sativa genetics, 20-25% THC, 10-12 weeks flowering, moderate grow.

Lineage: Jack Herer x Cinderella 99, run through an autoflowering structure by Blimburn Seeds, gives you a sativa-leaning plant that wraps up in 10–12 weeks without waiting on a light schedule. That speed matters if you're in a shorter Canadian season and want an outdoor pull before September turns cold. THC lands in the 20–25% range, which is meaningful for a strain this fast, and the flavour profile leans citrus-forward with a dry earthy finish that keeps it from being one-note sweet.

Indoors, growers are reporting 400–500 g/m², which is a solid return for an auto. Plants stay manageable in size, but they do respond well to low-stress training if you have the patience for it — that's where moderate difficulty comes in. This one suits growers who've already run an auto or two and want to push yield without committing to a photoperiod cycle.
