Aquaponics Nitrogen Cycle (Hybrid aquaponic system)

In this video I show you a presentation that I had to give for my Biology class this years semester (fall 2018). I gave a brief introduction of aquaponics and went into more depth of the nitrogen cycle that takes place in an aquaponics system. Basically how the fish waste is converted into nutrients for the plants. In the beginning I do say that you can't use pesticides. However there are some that you can. I would not recommend using any chemical anyways even if it can be used in an aquaponics system.
