So I decided to not risk shooting myself in the foot and take the advice of someone I respect. And I can say I no longer struggle with bacterial disease in my grow bags. I know Pro Mix is expensive but my growing success is worth it. But to each his own.

It's my understanding that he no longer dumps and starts new.(I could be wrong, but I really think I read that) I never dump, rather I solarize, which sterilizes the soil. Then I just replace nutrients and top off with some new.
