Lineage: Frosted Zinn crossed with 3 Bears OG, both carrying Seedsman's auto-selected traits, produces a plant that finishes seed-to-harvest in 9–11 weeks without any light-schedule fiddling. That convenience doesn't come at the cost of potency — the lab panel on this cross regularly reads 18–25% THC, and indoor growers pulling 400–550 g/m² are getting serious weight for an autoflower run.

The nose leans diesel with a grounding earthy base, nothing fruity or floral about it. Difficulty is rated easy, so first-timers won't be fighting the plant to hit those numbers, and it performs well indoors or out. If you've been skeptical about autos producing worthwhile yields, this cross makes a reasonable case against that hesitation.

Best suited for newer growers who want a no-fuss, high-THC auto, or experienced cultivators looking to squeeze a quick extra cycle into their grow calendar.
