Anyone with vast knowledge of powder mildew please?

1 teaspoon 3% Hydrogen Peroxide + 1 cup water. Apply as a foliar spray or water the soil with this solution. Completely safe for the plant and will kill PM.

Hello everyone. I’m posting here in hopes of acquiring the attention and knowledge of an advanced grower with experience with PM (powder mildew)
Is it something that can’t be gotten rid of ? Is eagle20 get rid of it ? Or do all the remedy’s people share just keep it from flaring up ? I’ve read of people who have had pm and then gotten rid of it. My friend is having some problems with it and has done all the obvious changes to help his situation. Anyhow if people could just share how they got rid of it that would be awesome. Thank you for your time !!

You probably won’t believe me but this shit works great and can be used while flowering(though I prefer not to). Same type of stuff they spray food with, says can be used up to 4 days before harvest.
Although not advertised for PM it always works

I fought with this stuff for a couple o years. I grow in a crawl space with too many sensitive electronics and mechanicals to burn sulfur, and foliars just added to the humidity. Had a bit of a seesaw effect!

After essentially just staving it off with foliars, and then having to wash that stuff off, I finally broke down and got one of these: https://www.cleanlightdirect.com/en/cleanlight-pro.html

I will see a spot or two if the humidity gets around 60%, but other than that, there has been nothing on the plants for over 4 months (and this is when I used to get it worst).

It's just a matter of sweeping over the plants daily, for now.

No more foliars, no more washing, save 2 oz's and it's paid for itself

Never had PM but run a strict IPM program but from what I understand is sulfur is the way to go. We don't burn it though, we buy the wettable sulfur from Lowes. Cost like $7 for a large supply. We also use Greencure as preventative. We spray down our mothers bi weekly alternating between the greencure and sulfur and anything right before we flip to flower we hit with a coat of the sulfur. It provides a protective barrier. Also good for killing off mites and anything trying to attach to your plant leaves.
The other issue is the source of the PM. If it is not on your leaves itself then you need to find it. It is somewhere in or near the garden being brought in through air spores. We run a UVC light with Ozone in all of our tents once a month to eliminate any spores and to sanitize. Of course we remove our plants when we do this. It is a process but the UVC and Ozone will disinfect stronger than bleach and kill any bugs or bug eggs. Just need to vent it out for about a half an hour before re-introducing plants
