KanMan Reviewed by KanMan on . flushing To flush or not to flush, that is the question. My last 2 harvests i flushed with clearex one week before harvest. During that last week, just ran pHed water thru the system. This harvest i am considering not using clearex but rather gradually reducing the nutrient mix during the final weeks and then just water for a couple of days. Any opinions would be appreciated.
