The best choice for a large commercial grower is a recirculating system. These systems save resources by using a pump to re-use the same water repeatedly to hydrate a large number of plants.
These commercial-use hydroponic systems recirculate the nutrients in a stock tank and automatically adjust the EC and PH of your nutrient solution. This method is both environmentally friendly and cost effective because it saves water. It also saves the owner time spent watering.
