A combination of aquaculture and hydroponics. Aquaculture is the cultivation of organisms in water and Hydroponics is the cultivation of plants without soil or earth. The Aquaponics combination integrates both techniques by growing fish and feeding and irrigating the crops with the same water. Aquaponics is a very efficient and sustainable way to grow vegetables and fish at the same time, for example in the garden or on the balcony. You need a basin with fish, a bin where you can put the plants and a pump that you place between them. This can be done in a small-scale manner, but is also strongly emerging in the large-scale sector such as greenhouse horticulture. This creates a cycle for you where fish and vegetables benefit and grow from each other. The principle has been around for centuries – the reuse of fertilizers used to be a necessity. Everywhere in the world you can find growth combinations of fish with vegetables, such as koi carp in the Japanese rice fields.
Plants purify the water
The stool of fish contains all kinds of substances that can act as food for plants – such as nitrogen, potassium, phosphorus and ammonia. They are converted into nitrate, which is absorbed by the plant roots. The water is thereby purified. Plants get almost everything they need in this way. They only need occasional supplementation of iron, calcium, potassium and possibly magnesium.
Fish feed the plants
The water contaminated by the fish is absorbed through the roots of the plants. There, naturally occurring bacteria convert the waste products of the fish into nitrates. That is fertile food for the plants in the system. This way, the water is largely purified by the plant roots, which are (partially or completely) in the water. However, using filters to filter residues from the water is not enough to reuse the water without problems. By using the H2O C-110 resonator all harmful elements are removed from the water and the water is 100% clean again and can be reused as fresh water for the fish.
Benefits of aquaponics
This natural and environmentally friendly way has many advantages:
- Maximum reuse of raw materials and manure
- Fully organic cultivation, when your plants live on the fish manure
- No weeds that compete for available nutrients and also lead to a lot of work
- System is flexible and small-scale to set up, and you can fit it into the available space
- Plants often grow faster, due to the continuous availability of nutrients
- Water consumption is much lower than in regular agriculture
- High yield and less labour-intensive
- Provides a contribution to self-sufficient living
