Overwhelmed by weak autos that don’t deliver?

Let’s be real: most autoflowering strains promise big but end up underwhelming—low potency, small yields, or bland flavor. You follow the steps, but the high is meh, the buds are airy, and the whole experience feels like a waste of time and space.

Imagine opening your tent and seeing compact, bushy plants covered in glistening trichomes—buds so dense they bend the branches. The air is sharp with a zesty lemon-pine punch. You harvest in under 11 weeks, vaporize a crumble, and feel a clean, euphoric rush that lifts your mood without locking you to the couch. That’s not a dream. That’s Calamity Jane Auto.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Calamity Jane Auto in my 1.20 m² (12.92 ft²) tent with a 600W LED and 20 L pots—no topping, just light LST. The smell hit hard by week 4, so I cranked up my Seedfinder filter. By week 10, the buds were rock-hard and dripping with resin. I flushed for 7 days, dried slow, and cured for 3 weeks. The high? Clean, euphoric, and long-lasting—like a Haze but smoother. For an auto, it’s next-level. I’ve since recommended it to friends who want quality without the wait. If you’re tired of weak autos, this one’s a must-try.
