Lineage: Frosted Zinn x 3 Bears OG, a Seedsman cross pulling from two resin-heavy parents to produce an autoflowering plant that finishes the full cycle in 9–11 weeks without any light-schedule management. THC tests have come in across a wide band—18% on the low end, up to 25% when conditions are dialled in—so your environment and feed program will influence where yours lands. Expect a dense, fuel-forward nose with an earthy base; not a fruit-forward smoke, more workshop-floor than fruit stand.

Yields run 400–550 g/m² under ideal indoor lighting, which is a realistic ceiling for the easy difficulty rating this strain carries. Because it handles both indoor and outdoor setups, it's a practical option for Canadian growers who want to run a balcony or greenhouse crop through the shorter warm season without committing to photoperiod timing. Good pick for newer growers who want a high-THC auto without a steep learning curve.
