if I were you, I would use the sulfur burner and canopy method. My master gardener friend had PM two years ago, infested half of his plants in like two days, and he said that it worked like a charm (though it does stunt growth, and he doesn't recommend doing it once they are deep into the flower cycle).
Money=Greed..... and greed is the most destructive power that I know to come out of fear... I must admit the I am susceptible just like everyone else to this weakness. My Cinderella is Female!
cheers....
