It is a brilliant idea indeed. It seems that the ancient hanging gardens utilised concepts from aquaponics which in turn are just simply observations from nature. It is a very rewarding hobby. We even have our own homegrown fish for dinner when it gets too overcrowded and they tilapias get quite big.

Did i mention that the second system we constructed allowed for the fish fry to take refuge in other parts of the system? meaning that we get a couple of hundred new fishies every year.
