Flowering 63 - 77 days 
Yield 450 g/m² Taste
Seb's take
Diesel and skunk over a sweet base on the nose, from a Jack Herer and pre-98 Bubba Kush cross bred to medicinal-grade standard. The effect is a decades-honed one — creative, happy, energetic, euphoric and giggly in a single 70% indica package.
Where it comes from
Medicann set Jack Herer against a pre-'98 cut of Bubba Kush, a famously energetic sativa-leaning classic on one side, a heavy indica of some pedigree on the other, and struck the balance at seventy percent indica. The house has been breeding and growing for several decades, and that unhurried experience shows in the finish. Two well-known names, then, brought together by people who plainly know their trade.
Nose & flavour
Diesel and skunk lead, pungent and unshy, over a sweeter base that softens the edges, this does not travel discreetly. The Jack Herer lends brightness, the Bubba a rounder depth. A proper old-school nose, fuel-forward and characterful.
The high
A busy, cheerful effect for something seventy percent indica, creative, happy, energetic, euphoric and giggly all at once, more lively than the genetics might suggest. The Jack Herer clearly has a hand on the wheel. Good company rather than a quiet night in, at a sensible 15 to 20 percent THC.
Growing it
A longer bloom than some, 63 to 77 days, so patience is asked for, with a yield around 450 g/m² and a listed 4 percent CBD alongside the 15 to 20 percent THC. No height figure is recorded, so watch her stretch and train as needed. The reward for the wait is a clean, well-made flower from a house that has had plenty of practice. Suited to a grower content to let a plant take its time.
