Personal Experience of Pevgrow’s CEO (Alan)

Amnesia Haze is one of those strains that reminds me why I got into this world. I grew it in my first serious indoor tent, and the moment I flipped it to flower, I knew I was in for something special. That stretch was insane — I had to LST like crazy to keep it under the light. But the effort paid off. The buds were dense, covered in trichomes, and the smell when I opened the jar after curing? Pure citrus and spice. The high is unlike anything else — it doesn’t just relax you, it expands your mind. I keep a small plant in my greenhouse every summer, and it’s become a ritual. I top it early, let it go wild, and by late October, I’ve got enough for months of clear, creative sessions. It’s not the easiest, but for a true sativa experience, it’s unmatched.
