Personal Experience of Pevgrow’s CEO (Alan)

When the guys at Pure Instinto dropped Auto MAC2, I knew I had to run it in my personal tent. I set up a quick 20/4 light cycle and honestly, the vigor out of the gate was insane. By week 5, the stretch was perfectly manageable, keeping it right around 1.00 m (3.28 ft), which is my sweet spot for indoor runs. The resin production is no joke—by late flowering, the sugar leaves looked like they were dipped in glass.

My biggest takeaway? Don't overfeed this beast early on. It thrives on a light nutrient schedule during veg, and then absolutely explodes when you hit it with a solid PK booster in weeks 6 and 7. The final smoke is that classic MAC experience: an immediate euphoric head rush that slowly melts into a super chill, functional body high. It’s easily one of my favorite quick-turnaround USA autos right now.
