Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of autos, but Auto Cinderella Jack stands out. I ran it in a small 60x60x160 cm tent under a 200W LED — just three plants in 20L pots. I used Bio Vega in veg and switched to Canna Boost in flowering. No fancy techniques — just consistent care. At week 10, the trichomes were milky with a hint of amber. I dried slowly over 8 days and cured for three weeks. The result? Dense, frosty buds with a sharp pine-citrus punch. The high hits fast — uplifting, creative, then deeply relaxing. Not for beginners in consumption, but a dream for growers who want power, speed, and quality in one package.
