Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Tropicana Cookies Purple Auto stands out. I ran three in my 1.2x1.2m tent under a 600W LED, 20/4 light cycle. They stayed compact, around 90 cm, but packed on dense colas by week 8. The smell was unreal — like pineapple and orange zest — so I had to roll with a carbon filter.

Harvested at 11 weeks, I got 470 g/m² after a 10-day flush and slow cure. The high is clean and motivating — perfect for daytime without anxiety. I’ve shared clones with friends, and they all agree: this one’s a keeper. If you want flavor, color, and ease, this auto delivers.

One tip: don’t top it. I tried LST only, and it responded perfectly. Push the PK slightly in week 6, and you’ll see resin build fast. Definitely one of my top 3 autos this year.
