The specs in one line: 17-23% THC, <1% CBD, 9-11 weeks total flowering, 450-600g/m² reported. Best indoor or outdoor. easy grow.

Lineage: Jack Herer × Shiva Skunk, shaped further with NL#5 x Haze x Skunk #1 in the mix — this F1 auto carries a family tree that explains a lot about how it grows. Plants stay compact and uniform, which matters if you're working with limited vertical space indoors or trying to keep things low-profile in a backyard or balcony setup. Flowering wraps up in 9–11 weeks from seed, and indoor growers regularly pull 450–600 g/m² despite the modest plant size. THC lands between 17–23%, so this isn't a light smoke, but the citrus and skunky nose gives you fair warning before harvest. The F1 structure means very little variation seed to seed — you're not sorting through phenotypes hoping one turns out decent.

Because it finishes quickly and handles cool, damp conditions without much fuss, this one suits Canadian growers in shorter-season regions like BC's coast, the Maritimes, or higher-elevation Prairie spots where a longer-flowering strain would be a gamble.

Indoor Growing: Expect a flowering time of 9-11 weeks total with yields of 450-600g/m². Plants typically reach 50-80cm indoors.

Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate.
