For crops grown in hydroponics, flushing should start a week before the harvest. All the grower needs to do is to replace the hydroponics solution with distilled water. Changing the water 2 to 3 times before the harvest will thoroughly remove any remnants of the hydroponics from the plant. If your plants were grown in soil with commercial fertilizer, flushing should be done 2 weeks prior to harvest. To speed up the whole process, dont water it 2 days before harvest. Provide continuous water flow for plants in hydroponics condition. The moment that the water supply is stopped, the plant will die.
