Frequently Asked Questions

Does Auto Sour Diesel smell a lot during flowering?

Yes, this strain is notorious for its extremely pungent gasoline aroma. If you are growing indoors, a high-quality carbon filter is absolutely mandatory to maintain discretion.

Can I top or prune this autoflower?

It is not recommended. Because of its fast life cycle, aggressive pruning like topping can stunt its growth. Instead, use gentle Low Stress Training (LST) to open up the canopy and increase light penetration.

What is the best light cycle for this strain?

For optimal yields and resin production, keep your indoor lights on an 18/6 or 20/4 schedule from germination all the way to harvest.

Personal Experience of Pevgrow’s CEO (Alan)

Whenever I want that classic, eye-watering gas aroma but don't have the patience for a long photoperiod run, Auto Sour Diesel is my go-to. It is incredibly straightforward to grow; you just plant it in a large pot, give it plenty of light, and watch it explode. The Super Skunk genetics really beef up the structure, so the branches can handle the weight of those dense, sticky buds.

What I love most is the effect. It is my absolute favorite for weekend mornings or when I need a creative spark for a project. It doesn't drag you down or make you sluggish. Just pure, uplifting energy with a flavor that coats your mouth in diesel and citrus. It is a must-have in any serious grower's stash.
