Thought I'd share my own problems with pm too.
I get lots of pm outdoors where I am. It's a cold, wet climate.
By late summer, or early autumn, it's a lot cooler during the night. We have warm, humid days. Then cold, damp nights.
Pm spores are around all the time. As a grower, we need to minimize the risk of pm infecting our grows.
Imo the biggest factor is environment. You need to break the pm's life cycle. Powdery mildew needs moister and high humidity to grow. Also it needs to dry so it can spread spores.
It's about keeping humidity and temps in range. Especially during lights out. Lots of air exchange, and circulation is key as well.
Prevention is the most effective thing.
Some things to check over, and keep in mind if you didn't know already.
Humidity.
Especially at night / lights out.
Airflow.
Good circulation, and exchange.
Temperature.
Especially at night / lights out.
Good pruning.
No clutter in the center of the plant.
