If you think you have the ability to make a plant rid itself of what you want, why isn't flushing done in 1 day? 9/10 times when you taste "harsh" weed it's because you didn't CURE right. I grow coco and feed full nutes to the last day before chop. If been told some of my smoke was the smoothest ever. I feel I've got my CURE down. You believe it's flushing but have no facts about flushing except what you read. I know my cure helps my outcome. You don't know what makes the weed you smoke taste bad. Bad genetics, bad cure, bad growing(most likley from novice house growers). Is what it is. Flushing was made to sell products. Nothing more, nothing less.
