In hydroponics, the grower must control aspects of a plant’s environment very closely - more so than standard plant growing conditions with soil. Hydroponics is the practice of growing plants in a water system. An extension of this, is also referred to as aquaponics - the use of water and fish to grow crops. In either system, there is no soil as water serves the purpose of the growing medium. With this in mind, a grower must monitor all levels within the system to ensure plants are able to absorb and utilize nutrients for proper growth and excellent yields. One of the most important parts in maintaining a hydroponic system is the control of pH or potential hydrogen.
With such great importance on pH control, a large-scale commercial greenhouse operation should keep track of the pH in their hydroponic systems and growing areas to ensure proper growth of their crops. By doing this, a commercial grower will lower costs, increase yields, and receive maximum return on investment.
