Thats not flushing. To flush, its just like it sounds. I personally take the water hose and just let it run on it for about 30 minutes. You be the judge on how high to turn the water on. I have 3 gallon pots, I turn the water on about 1/4 of the way and just let it run for 30 minutes while it is washing everything out the bottom. But then again, I quit using chemicals. I use all organic and I dont see the need to flush now.I am looking for a way to flush out the chemicals (fertilizer etc.) from my plants before harvest. I am using molasses 1tsp gal water.This is my first real harvest, I'm not sure if this is the best way or what..
