For those who have no idea what aquaponics is, I have compiled a few videos explaining the principles and how aquaponics works. Note that my DripGrow towers work for both hydroponics (nutrient water only) and aquaponics (no fish involved). For videos on growing microgreens, please click here.

NOTE on February 3, 2020: I just learned about the most original version of Aquaponics called Integrated Aqua-Vegeculture Sytem, or iAVS for short. It has solved most of the problems that are associated with the most common Flood and Drain Hydroton-based system, a bad twist of the earlier version. So the first of the three videos is about iAVS and the rest about Aquaponics in general. Brief introduction to iAVS:

This video explains aquaponics using animation:

This one uses animation too:

This explains the problems with Aquaculture and Hydroponics, and why combining them:

See how Rob Bob explains it:

See how Myles Harston of AquaRanch Industries explains it:

See how Arturo explains it:

See how this video explains DIY and commercial aquaponics:

Simply put, aquaponics combines fish raising and plant growing together so that one can benefit another.
