Personal Experience of Pevgrow’s CEO (Alan)

I grew North Thunderfuck last season in my 1.20x1.20 m tent with a 600W LED. I topped at five nodes and used SCROG to maximize yield. The stretch was moderate, and the plant filled the net perfectly. At 58 days, the trichomes were milky with a hint of amber—harvested and dried slowly. The high is unreal: euphoric at first, then a deep, relaxing body stone. It’s not lazy—just perfectly balanced. I’d rank it among the top 5 strains for flavor and effect. One thing: the smell is strong, so don’t skip the carbon filter. I’ll definitely grow it again.
