Another reason I like hydro. I don't start flushing until the bud growth has stopped. Pretty much the last 5-7 days while they finish maturing.I think most people have a hard time hearing that all the time they've spent flushing there buds only made their herb less potent along with a smaller yield.
When I do this, the buds are clean and tasty, even quick dried. A cure brings out the full flavor of course but, that flush with little to no nutes is the bomb.
