Air Stones




Air Stones are an ideal way to add oxygen to your hydroponic growing system.

Air stones aerate the nutrient solution and improve nutrient circulation which extends the life of your nutrient solution, help keep roots healthy, and promote exceptional growth.

We have a range of Air Stones for every application, be it adding oxygen to your tanks or for actually oxygenating your growing system. All these connect via Air piping to Air Pumps and Air Compressors.

Air diffuses into water whenever water comes in contact with air. This commonly occurs when water on the surface of a reservoir touches the air in a grow room or when air bubbles rise through a column of water in a reservoir. Many growers employ the combination of an air pump and air stone to add oxygen to their fertigation solution (the mixture of water and fertilizer). This is a viable option for many growers and one that is able to increase dissolved oxygen levels fairly inexpensively. An air pump pumps air through food grade plastic tubing to the bottom of the reservoir, where it is attached to an air stone. The air stone then diffuses the air into small bubbles which rise through the water, increasing the dissolved oxygen level as they rise. This also happens to be a great method for keeping one’s water and fertilizer mixed, preventing the fertilizer from settling to the bottom of the reservoir.

Air curtains are sometimes preferred in applications where regular air stones clog up too quickly, or become brittle quickly ( eg. compost teas / high H2O2 presence )

PLEASE NOTE: Air Stones may vary depending on supply.
