Personal Experience of Pevgrow’s CEO (Alan)

When I first popped Blue OG in my personal tent, I was immediately struck by how sturdy and compact it stayed during the vegetative phase. I organize my cycle by keeping the feeding relatively light early on, as this strain doesn't need a heavy hand to thrive. One mistake I made initially was not defoliating enough in the lower canopy; once I cleared out the bottom third, the top colas swelled up beautifully and the resin production went through the roof. The smell of sweet berries and Kush in the final weeks is absolutely intoxicating, and the balanced high makes it one of my favorite afternoon smokes.
