What is Aquaponics?
Aquaponics is a sustainable and efficient system that combines hydroponics with aquaculture. It is a closed-loop system where fish waste provides nutrients for the plants, and the plants filter the water for the fish. In other words, it’s a self-contained ecosystem that allows for the growth of both fish and plants in a symbiotic relationship.
How does it work?
| Fish Tank | Grow Bed |
|---|---|
| The fish tank is where the fish live and produce waste. The waste contains ammonia, which is toxic to the fish and plants if left untreated. | The grow bed is where the plants grow. It is filled with a growing medium that supports the plants and provides a surface area for bacteria to break down the ammonia into nitrites and then into nitrates. |
| The water from the fish tank is pumped into the grow bed. | The plants take up the nitrates as nutrients and purify the water before it flows back into the fish tank. |
| This process repeats, creating a continuous cycle of nutrient-rich water for the plants and clean water for the fish. |
What plants can you grow in an aquaponic system?
You can grow a wide variety of plants in an aquaponic system, including lettuce, herbs, tomatoes, cucumbers, strawberries, and even flowers.
