Learning about aquaponics

GreenLab is a technology hub supporting the design of new sustainable food systems.

It’s just on the border with Southwark, but we decided to make the most of this new facility and see if we could help increase green tech knowledge amongst our members. We funded five Incredible Edible Lambeth members to attend a workshop on aquaponics in November 2017.

We learnt about the benefits of ‘closed loop’ systems; in aquaponics, fish provide the fertilizer for growing greens such as salads, and in turn the plants clean the water for the fish.

We learnt how to build a complete system using mainly recycled materials, for around £100. The main costs are a water pump and some plumbing. The pump does require electricity.
