Personal Experience of Pevgrow’s CEO (Alan)

I have a massive soft spot for the genetics that built the foundation of modern cannabis, and NHS is absolute royalty. I remember popping a pack of these a few years back, looking for a mother plant that had that unmistakable 90s Amsterdam coffee shop vibe. The vigor on these plants is insane—you can literally see the Skunk and Haze fighting for dominance in the structure. I highly recommend topping them early and throwing a net over them, because once you flip to 12/12, they take off.

What I love most is the smell during late flowering; it’s this aggressive, eye-watering Skunk mixed with a sharp, spicy Haze that takes me right back in time. If I didn't have a top-tier carbon filter, my whole neighborhood would have known what I was up to. The high is exactly what you want from a classic: it hits you right behind the eyes with a rush of pure joy, and then melts down into your body. A little trick I learned: let it go a few days past the 70-day mark if you want a heavier, more narcotic physical effect. It’s a true keeper.
