Air Pumps and Airstones

Plant roots thrive when they are given water which has a  high level of dissolved oxygen in it. By using an air pump and an airstone in your feed water, the level of dissolved oxygen can be kept high, almost to saturation point.

The dissolved oxygen does two things: firstly, it keeps the plant roots healthy; secondly, it allows beneficial microbes to breath. Friendly microbes usually like planty of oxygen but bad microbes that can cause infections are usually anaerobic (do not use oxygen).

In a reservoir, the motion of the bubbling action will help to keep the nutrient solution well mixed.

In a DWC system, it is essential to use an air pump and airstone or else the plants roots will basicallly drown. If you run a DWC system it is a very good idea to keep and spare air pump handy in case one fails.
