Aquaponics is a recirculating system that combines hydroponics (growing plants in water without soil) and aquaculture (fish farming) to create an efficient closed loop system:
– We feed the fish
– The fish poo
– The nutrient rich waste-water from the fish tanks is pumped to the roots of the plants where microbacteria convert the waste nutrients into helpful nutrients
– The nutrients fertilise the plants and in turn the plants purify the water
– The water is then pumped back into the fish tanks
The only inputs into the system are the fish food, and the energy for the pumps and water heaters – we don’t use any chemical fertilisers or pesticides.
As the water is fed directly to the roots of the plants and then recirculated to the fish tanks, the system uses much less water than traditional agriculture. This low energy, low water-use system is an environmentally conscious way of growing food and is especially suited to high density urban agriculture.
Vertical farming is the practice of producing food in vertically stacked layers in an indoor controlled growing environment.
- We create more productive growing space by building upwards
- We produce crops all year round
- By growing in the city, close to consumers, we slash the transport costs and carbon-dioxide emissions associated with moving food over long distances.
- Being close to market means we reduce spoilage that inevitably occurs along the way
- We do not use any pesticides, herbicides or fungicides in our aquaponics system.
- Because we can control temperature, humidity, lighting, airflow and nutrient conditions, we can get the best productivity out of plants year round, anywhere in the world.
