No. iAVs (Sandponics) pre-dates everything we know as aquaponics. It was the first successful ‘closed loop’ integration of fish and plants.
The three principal variants on the aquaponics theme are (in chronological order) sandponics, flood and drain and deep water culture. iAVs utilizes sand as the growing media. Flood and drain aquaponics uses gravel, clay pebbles or other coarse media and actually resulted from a failed attempt to build an iAVs.
Deep water culture (DWC) – also known as raft culture – has no media as such. The plants are supported by the rafts, with their roots in direct contact with the water.
Sand is not the only distinction between iAVs. Furrows, intermittent daytime irrigation, the detritus layer and soil microbiology are all unique features of the method.
