Personal Experience of Pevgrow’s CEO (Alan)

I grew Royal Bluematic Auto in my balcony garden last summer, and honestly, it was the most stress-free grow I’ve had in years. I planted three seeds in 20 L pots with Canna Bio Terra Plus, watered them every other day, and didn’t touch a nutrient until week three. No pruning, no training—just set it and forget it. By week eight, I had three dense, frosty colas that smelled like fresh blueberry pie. I vaped it first—smooth, sweet, and perfectly calming. No anxiety, no paranoia, just a gentle body buzz that helped me unwind after long days. I’ve shared it with friends who suffer from stress, and they all asked for seeds. If you want quality, speed, and simplicity, this one’s a no-brainer.
