Frequently Asked Questions

Is this strain really strong enough for experienced growers?

Absolutely. With up to 24% THC and a complex terpene profile, it delivers a potent, balanced high that satisfies even seasoned users. It’s not just beginner-friendly—it’s connoisseur-approved.

Can I grow it with other strains or should it stand alone?

It works great in mixed grows. Its compact size and stable cycle make it easy to fit into any setup. Just keep lighting at 18–20h and avoid sharing nutrients with photoperiods on 12/12.

What’s the best way to maximize yield without overcomplicating things?

Use low-stress training (LST) early, maintain consistent light and feeding, and add a bloom booster like Massive Bloom in the second half of flowering. That’s all you need for top results.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of autos, but this one changed how I grow. I used to rotate five different strains, always chasing flavor or yield. Then I tried Auto Frosted Zinn x 3 Bears OG—and stopped. It hits everything: fast, frosty, flavorful, and foolproof. I run it in a 60x60x160 cm tent with a 250W LED, 18/20h light, and Maria Green’s starter pack. I do light LST on day 10, then leave it alone. By day 75, I’m trimming dense, trichome-covered buds that smell like sweet pine and OG. The high is clear, uplifting, then gently relaxing—perfect after work. I don’t need anything else.
