Personal Experience of Pevgrow’s CEO (Alan)

I grew Red Strawberry Banana Auto® side by side with a standard autoflower, and the difference was night and day. From week five, the colors started popping — deep reds and purples that made my grow tent look like a candy store. The smell? Like walking into a bakery full of fruit tarts. I ran a 20/4 light cycle with moderate feeding, and by week eight, I had dense, frosty buds that sparkled under the LED. I didn’t top it — just a little LST to open up the canopy. The high was smooth, relaxing, and surprisingly uplifting. Perfect for unwinding after work or sparking a creative session. If you want fast, flavorful, and beautiful — this one’s a no-brainer.
