Personal Experience of Pevgrow’s CEO (Alan)

I grew Mr. Nice G13 X Hash Plant® in my outdoor garden last summer, and it was a game-changer. The plants stayed compact but exploded in flowering, producing dense, rock-hard buds covered in trichomes. The smell was incredible—earthy, spicy, with a sweet hashy depth that filled the garden. I used Bactomatik Rex from week two, and the root development was insane. No pests, no mold, just pure resilience. The high? Instant. Full-body relaxation, perfect for unwinding after a long day. I saved a male to experiment with crosses this season. If you want a strain with legacy, power, and breeder potential, this is it.
