This is something I found from a quick Google search, it might help answer your question about how PM survives/thrives:
Powdery mildews are severe in warm, dry weather because, unlike most fungi, powdery mildew require a wet leaf surface for infection to occur. However, the relative humidity of the air does need to be high for spore germination. Therefore, the disease is common in crowded plantings where air circulation is poor and in damp, shaded areas. Incidence of infection increases as relative humidity rises to 90 percent, but it does not occur when leaf surfaces are wet (e.g., in a rain shower).

Nice. You could do better if you'd listen instead of argue though. Some strains do better in low rh than others.i run 78f & 30% rh lights on and 65f & 35%rh at night and im pretty sure my plants r getting plenty of co2.i think it comes down to what they get used to,what they were germed and vegged in as well.heres a pic just to show co2 intake lol

You make a valid point. I was just speaking what I know to be true. A high rh can be tricky in a high desert environment. Not always the path for a newbie. I was just stating the facts that plants perform waaaaaay better (STRAIN DEPENDENT OF COURSE) in an environment where the vpd is dialed in. No offense. Your picture looked good.I didnt think I was arguing, just giving my personal experiences.you tell new growers to run @ 70% they are bound to have multiple problems. Can I do better? Sure I can but running 15 to 20 strains at any given time I prefer to not take chances with molds and budgrot. especially on stuff I have never run and have no idea if its mold resistant. All im saying is you better have everything else in check if you run65 to 70% rh.imo of course.guess ill look around for some of these high rh grows and see whos killin it.peace
I actually use the Young Living Thieves Oil. I use an ultrasonic diffuser to get the oils into the air, and I also use the Thieves household cleaner to clean the grow. I keep a bottle of the oil blend and the household cleaner on me when I remodel also. If there is mold behind a wall or something I use it immediately. Also, fungus gnats detest the cinnamon in the blend. Mites hate the clove and rosemary, too, but I never spray it on my plants.@ attitudefarmer got a recipe for those essential oils?per gallon?

Why is that brother in regards to 65-70 RH in the high desert? I live in the high desert and have yet to come across info in that regard. I just want to play it safe.
I think there are tons of spores, etc around that never manifest because the humidity isn't here. They get blown in on the wind, etc. Create a humid environment and add a little dust>>>> bam, you have all kinds of jungle fungus. In CO, we blame winds from Cali, lol.Why is that brother in regards to 65-70 RH in the high desert? I live in the high desert and have yet to come across info in that regard.

I see it on my squashes almost annually, late season. Have had one instance of PM during a root aphid battle and those girls couldn't have fought off Tyrion Lannister with a stick. Have received MANY cuts with PM, RH is not the problem, plant health is. Get them healthy (that usually means not pushing them artificially) and its relevance in the garden is reduced.have you had it?if so,what caused it?
