Air Stones are a great way to add oxygen to your hydroponic growing system. Air stones improve nutrient circulation in the water which extends the life of your nutrient solution, helps keep roots healthy, and promote exceptional growth. Air Stones create small bubbles which rise through the water increasing circulation and increase the dissolved oxygen levels fairly inexpensively. All these connect via Air piping to Air Pumps.
PLEASE NOTE: Air Stones may vary depending on supply.
