==Description==
'''Ebb and flow''' or ''ebb and flood'' is a term used to [[describe]] the movement of [[water]], often in relation to natural [[tides]]. It is commonly used [[metaphorically]].
*In Hydroponics
Ebb and flow (E & F) aka "Flood & Drain" (F & D) is a form of [http://en.wikipedia.org/wiki/Hydroponics hydroponics] that is known for its [[simplicity]], reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not [[function]] like [[soil]] or contribute [[nutrition]] to the plants but which anchors the [[roots]] and functions as a temporary reserve of water and solvent mineral nutrients. The hydroponic solution alternately floods the system and is allowed to ebb away.
