Oh yeah it's good to spray your plants down and get rid of any dust that your fans may have blown on them, i do that every chance i get, only with plain old h2o.. And I'm sure your methods are sound,I simply don't have the time.. I visit my site once a week, and stay too busy to care for my babies as they should be. I'm just about taking care of the problem ASAP. So I had to take care of it my way because not doing so could've screwed my crop over any one of the days I'm gone.. But mites are old news, for me they were the easiest thing in the world to take care of.. 5 years is a long time ago and
Avid was the best thing shop owners recommended themselves. Mites, mildew,mold, just about anything can and more than likely will build a resistance to whatever were spraying.. It's only a matter of time.
Oh and scrubbing my rooms up really good is just something I do all the time. I spray down walls, clean out pots, lights, floors, the works. Not because I must, just like keeping clean and keeping busy. After every flower cycle
