Aquaponics is a methodology which combines the best parts of hydroponics and aquaculture to enable you to grow fish and plants in a symbiotic manner.
The fish poo and other byproduct is pumped or drained into growbeds which have micro-organisms in that convert the fish waste to plant food. The plants absorb these wastes and what water they need and return clean water back to the fish tank.
You can choose to grow edible fish in the system, meaning that you can harvest fish as well as vegetables, herbs and fruit, or you can choose to grow gold fish and have the most beautiful flowers in town. See a video of our first complete system experiment Photo Album of the set up at the shop
