Personal Experience of Pevgrow’s CEO (Alan)

I’ll admit—I used to think high-THC and autoflower were mutually exclusive. Then I grew Wham Boom Auto. In under 10 weeks, I had sticky, purple-tinged buds that tested at 31% THC. The flavor? Insane—like dessert with a citrus punch. I’ve since switched two of my indoor rooms to run back-to-back autos, and this strain is the star. No topping, no SCROG, just plant and watch it explode. If you want power, speed, and flavor without the hassle, this is your seed. Trust me, your next favorite grow starts here.
