How to grow Gorilla Girl XL Auto successfully

Personal Experience of Pevgrow’s CEO (Alan)

I was skeptical at first—another 'high-THC auto' claim. But Gorilla Girl XL Auto proved me wrong. I grew four in 20L pots indoors under full-spectrum LEDs, and by week 8, they were towering, sticky beasts. The smell alone was worth it: sweet pine with a diesel kick. I harvested 512 g/m², and the high? Clean, uplifting, and long-lasting—perfect for creative sessions or chilling with friends. No nutrient burns, no mold issues. My only tip: don’t crowd them. Give space, use LST early, and let this beast shine. It’s now my go-to recommendation for anyone wanting power, speed, and flavor in one package.
