Its fundamental principle involves the continuous or intermittent flow of a very shallow stream of aqueous nutrient solution in the hydroponics unit channels where it forms a thin film around and on the bare roots of growing plants.</p> <p>Plants are typically housed in inert growing media (like Rockwool or clay balls) within channels or gullies, which are precisely sloped to facilitate the flow by help of gravity. </p> <p>A nutrient solution is pumped from a central reservoir to the highest point of the channels. It then flows down the slope, creating a thin film (typically a few millimeters deep).
