How to grow Watermelon Zkittlez Auto for best results

Keep it simple: plant in a 20 L pot, use quality soil, and let it shine under 18–20 hours of light. Avoid topping — this auto doesn’t need it. Water when the top inch of soil is dry, and feed lightly. For a stronger start, Barneys Farm seeds pair perfectly with root boosters like BN-Roots to maximize early development. In mid-flower, support branches if needed and maintain humidity at 40–50%. A carbon filter is recommended — this one smells like a candy store.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of autos, but Watermelon Zkittlez Auto stood out immediately. I used to stick with basic strains that barely impressed — until I tried this one. Planted it in a 20 L Monkey Soil pot, gave it 18 hours of light, and barely touched it. No topping, no LST, no drama. By day 75, I had chunky, resin-dripping colas that smelled like a fruit stand. Dried slow, cured for three weeks — the flavor was unreal: sweet, tangy, with a hint of diesel. The high? Smooth, uplifting, perfect for chilling with friends or unwinding after work. I’ve recommended it to beginners and veterans alike. If you want a fast, flavorful, high-THC auto that actually delivers, this is it. My only tip: don’t skip the cure — it makes all the difference.
