Future Harvest - Plant Flush - Double Flush
There are certain compounds of nutrients that you do not want in your final product. By flushing your plant with plain water before harvest, it will force it to use up these unwanted compounds which will result in a cleaner product.
Plant Flush will stop any further intake of nutrients through the roots and will cause the plant to only use the nutrients stored within the plant.
This will greatly reduce the amount of time you need to flush your plants in order to achieve a cleaner end product!
