The key is early detection. Overcrowding is said to create an environment for it to take hold. I think overcrowding is also a way for it to go undetected for longer. In the world of 'regular' agriculture, new fungicides are constantly being developed. It's almost impossible to stay ahead of the new variants that keep coming out. Apparently, powdery mildew evolves faster than any other organism. I've fought with it for years (ever since I moved here), yet some folks say they sprayed once with baking soda and soapy water and it was gone. Why the disparity? I think it's because ALMOST getting rid of it in a perpetual grow situation helps the PM adapt and become stronger. My 'folly' is to keep holding onto mother plants of strains I like. Growing from seed is the way I'm going now. I don't see any of it anywhere in my house but I know if I turn my back it will return.
An owner of a local grow facility told me he uses UVC and HEPA filters on incoming air, and keeps his building under a positive pressure. His workers have specific work areas to avoid cross contamination. Also, he says he uses Kangen water to spray the leaves. The high pH water and low pH water are used to change the pH of the leave surface to discourage PM. That's how baking soda works, but it leaves residue. The Kangen water is much cleaner to use- but EXPENSIVE to produce. The low pH water has hypochlorous acid in it, which quickly degrades after production. The water must be used fairly fresh. The time to learn about powdery mildew is before you get it, not after.
Generally spread through the air is a far more accurate statement. It can be spread by clones but also just walking in the garden center at home depot or your back yard. PM is just something that exists almost everywhere where the humidity and temperatures allow. That’s why cleanliness is key to keep indoor gardens healthy and happy. Will this post ? Or remain hidden like the others.
I bought an Air-o-Clean air cleaner that uses UVC and 'photocatalytic oxidation' to destroy spores in the air. I guess the problem with that is that some of the spores land on a neighboring plant and take hold before they can get to the air cleaner. It cost me 1700 dollars and needs 200 bucks in filters and bulbs/year. The mildew didn't seem to notice. Thinking of viruses recently, I thought maybe it would be a good idea for climate control systems to have air travelling in an upward direction. If somebody breathed out a virus or bacteria, it would rise and be neutralized, rather than travelling sideways to the next person. Exchange people and viruses with plants and spores, and it seems (to me) that it could be effective.
I have to say it’s works for me. Though I don’t just wash , I’ll plunge it in and out of 3 bucks 1st hot water 1/3 cup of lemon juice and baking soda , 2nd 1/2 peroxide warm water , 3rd ice water for rinsing, hang in front of a fan until no longer dripping hang for drying. I separate the effective areas to a different drying location and monitor the dry session. I’ve had great success.
I asked this question in a forum if i can use baking soda against powdery mildew, they told me to add some flower bring the light closer so you can bake a cake instead of growing@@robertpaprocki2582
It IS that pervasive where I live. It's the most common cannabis problem here at home and at the grow store where I work. It also ruins gardens here. I live a stone's throw from Lake Erie. BIG problem here! A guy I spoke to that owns a grow facility told me he spent 400,000 dollars on UVC lighting alone to combat PM. The lights are in the air intakes, so they don't kill the plants and the people, just the PM spores that try to come in. As a home grower for 4 decades, I can honestly say that this is a relatively new crisis. And it IS a crisis for many of us. I grew for over 25 years without ever seeing PM. A lot of folks don't know that PM is not just one thing. There are as many strains as there are marijuana strains. OK, maybe not NOW ;) I have read thousands of pages about this, and used many products and practices to combat it, with varying levels of success. I respect Jorge Cervantes, but hydrogen peroxide does not work to kill it, or to wash it off. What's being washed off is only the loose fruiting bodies that help it spread.

If you know mildew and mold, the answer is NO
check ph & spray with baking soda
Read my post.
@@robertpaprocki2582deluded rubbing alcohol in a spray bottle works for protection as well.

If PM was really this pervasive half the weed grown in the world would end up in the trash.
