Soil-less Gardens - Aquaponics/Bioponics
Here is a link to my what I believe to be the Perfect Aquaponic System
I have come to prefer Bioponics, and Hydroponics over Aquaponics, but they are all very similar.
While the concept of fish and plants creating a symbiotic and sustainable nutrient balance appears to take care of itself; my experience has shown that it may take well over a year for Bioponic and Aquaponic systems to mature.
My results were mixed, but the grand success of others keeps, and the ease of propagating in soil-less gardens keeps me in the game. My experience has been documented on my Aquaponic Blog .
