Flushing is the act of trying to remove all the extra salts, nutrients, and other impurities that build up in your plants just before you harvest. Most growers flush their plants by providing them with plain water devoid of nutrients for a certain amount of time. By watering like usual but with no nutrients, it serves to wash off the excess accumulation.
You might want to think twice before flushing your plants with plain water because there is a drawback to this method of flushing. It is recommended to use FLUSHING agents.
Why You Should Flush Before Harvest
Flushing is a simple and cost-free approach to improve the eventual harvest's quality. Why? Plants accumulate too many salts and other harsh compounds because they grow by absorbing compounds from nutrients, water, and the environment.
You risk lowering the final quality of your crops if you don't get rid of these surpluses prior to harvest.
