Ebb and Flow Systems

In the last article, we talked about three of the more common styles of Hydroponics: NFT (Nutrient Film Technique), DWC (Deepwater culture) and Aeroponics. We left one more popular style out of that article, a type of hydroponic system called Ebb and Flow.

Ebb and flow systems repeatedly flood a grow area with nutrient-laden water, then automatically (passively) drain that water back to the source tank for recirculation. Some Ebb and Flow systems flood an area where plants are growing in media like rocks or clay pebbles, while others may flood an area in which a raft filled with individual plants is growing in isolated media (generally for larger plants like fruit and marijuana).
