Nevar! Nor have I heard that before, definitely seems counter intuitive, I agree. The fan thing I learned the hard way, and I don't want anyone else to repeat my mistake.
Sulpher vaporizer users help

That wetting down or misting was in the instructions of a 'store bought' burner. Mine is a DIY, so I didn't have instructions..
Then, it was mentioned again. Still, wetting leaves with PM doesn't make sense. Burn still worked as advertised. LOL
BTW, there were 4 people who responded and none wet the leaves. 2 with store bought and 2 with DIY burners.

That's strange. After thinking it through, I can understand the logic behind wetting the leaves, as it would make the sulpher vapor stick to the leaves as a very thin coating which would (possibly?) allow it create a somewhat systemic effect by transport through the stomata which wouldn't happen without the water. The reason I thought it was counter intuitive was for that specific reason; that it would make the sulpher stick to the leaves, rather than just a surface treatment. I'm totally guessing at all of this though, in no way is this verified.
It probably is much more effective that way, but I'm not doing it. After my condensation issue I had half of my garden literally crop dusted with the stuff, they looked like a bag of yellow flour had been blown through my fans all over everything. I still don't clearly understand why that happens though.

Seems like there is a lot of confusion on here about PM and sulfur vapes. Here is some great info about PM, everything you need to know about it is on this site: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7494.html (search around on there too)
As for the vape, I've found that for most PM problems short 2-3 hour burns are sufficient and will keep your plants from picking up the sulfur smell if you're in bloom. 6-8 hour burns seem to stress the plants out and your buds will end up smelling and tasting like egg farts. Too much sulfur is toxic for humans too so you don't want to be consuming it... I've done short burns (2 hours) up to weeks 5-6 on 9 week runs with no problems.
PM doesn't need moisture to form, it will pull what it needs from your plant. Some strains of PM actually don't like water on the leaf surface at all.. I live in Colorado and it's dry as hell here and PM is a serious problem even with grows with rH at like 30-40%. I've found that big swings in temp will set it off more often than anything. Even if your garden never hits a dew point you'll see it if the temp swings. It's a big problem indoors here in the winter. You see it pop up with temp variances around 20 degrees or more. In addition to vaping you might want to try spraying your plants with some water with a surfactant added, (dish detergent or sm-90). It will help wash away some of the spores and can actually drown them. That UC Davis site I linked to has great info for every major pest / disease out there. We use that site as a resource at our commercial grow. When in doubt go there.
