Personal Experience of Pevgrow’s CEO (Alan)

I grew Dos Si Dos Auto in my 1.2 x 1.2 m tent with a 600W LED and 20 L pots. From day one, it stood out—vibrant green leaves, strong stem, and a smell that filled the room by week 6. I used LST gently to spread the canopy and applied Piranha at transplant and Overdrive from week 3 of flower. No pests, no deficiencies. Harvested at 75 days with 612 g/m² of frosty, dense buds. The flavor is unreal—like lemon pie with a gassy kick. It’s now one of my go-to autos for quality and consistency. My pro tip? Don’t top it—let the main cola dominate. You’ll get better vertical growth and easier management.
