Flushes are for use at the very final stage of flowering, they work especially well in hydroponic systems as they are designed to clean any nutrient or salt buildup before you harvest your plants. Flushing is important, and in soil it is usually done with just pure water. Because your plant, by the end of flower, is saturated with nutrients, it is always good to take time to allow the plant to use up its stores of nutreints before cutting it down. Flushing takes harsh, chemical flavors out of your final fruits and flowers, leaving you with the full flavor profile of the plant’s genetics and phenotype.
