Other than nivek saying it's hard to wash off (a chance I would gladly take until someone post a link to the dangers of inhaling burned leftover milk solids), I have only read that it's a preventative for PM.
I'll see what happens with the PM and the weather over the next couple days and do some research and go from there. if I don't find anything negative about it I will use it. I'm pretty confident that it kills and prevents.
Gosh shedder. That is a strong mix. Least according to jorge cervantez. He mixes one cup in five gals of water to wash buds. I have been following his guidelines more or less
One thing i do do when i wash mine in h202 is to arm swing the buds dry. Hard. Hold on tho. No ill affects but removes so much liquid
