“Been listening to NPK for a while now and the content just keeps getting better. I used to follow the "Dude Grows Show" podcast religiously, but NPK has taken its place for me - NPK has more technical content, less product specific promotion and the NPK guys consistently demonstrate a TRUE understanding of the science behind what they say. Big fan.”
