Are you tired of weak strains that don’t deliver the knockout punch you’re after?

You’ve tried the trendy new genetics, but they lack that old-school muscle. You want something pungent, potent, and predictable—especially if you're growing in tight spaces or need discretion.

That lingering disappointment when your harvest smells more like hay than gasoline?

It’s frustrating when your plant stretches out of control, demands constant attention, or collapses under minor stress. You don’t have time for finicky genetics that fail when temperatures dip or pests appear. You need a strain that’s built tough and delivers every time.

Original Auto Chemdawg is the no-nonsense, fuel-injected autoflower that grows like a tank and hits like a freight train.

This indica-dominant hybrid combines the legendary Chemdawg lineage with rock-solid autoflower resilience. It stays short and sturdy—ideal for stealth setups—while packing THC levels up to 20%. With minimal maintenance and high resistance to cold and pests, it’s ready to harvest in just 8–9 weeks, producing dense, trichome-bombed buds that reek of diesel and earth.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Original Auto Chemdawg stands out for its raw power and reliability. I first tried it in a small 60x60 cm tent with a 250W LED—just three plants in 20L pots. I used a simple soil mix with some bat guano and went light on nutrients. By week 8, the smell was insane—like a gas station with a hint of fruit punch. I didn’t train them much, just a little LST to spread the tops. Harvest was around 380 g/m², and the buds were rock-hard with a frosty coat of trichomes. After drying and curing, the high was exactly what I needed: heavy, full-body relaxation without knocking me out. I’ve recommended it to friends who are just starting, and even my more experienced buddies come back for its old-school vibe. If you want a no-BS strain that delivers every time, this is it.
