Vertical growing, fuelled by fish.

We're aquaponic urban farmers in London

Join us for a tour or training session

We engage, educate and inspire communities about sustainable food production and help people make informed decisions about the food they buy and eat. We produce sustainable fresh fish, salads and herbs in cities using a combination of aquaponic and vertical growing technologies.


Current Projects

GrowUp at Green Lab

We have compiled our equipment and know-how into a first of its kind exhibition of urban farming. Whether you’re interested in growing indoors, outdoors, at scale, or at home, this is the place to start your journey. From our installation at Green Lab we deliver our educational programme of public tours and industry training thoughout the year.

The GrowUp Box

The GrowUp Box

The GrowUp Box was our flagship urban farm and produced over 435kg of sustainable salads and herbs and 150kg of fish annually. Both our growing and educational programme were seasonal, and in 2018 we took the decision to move its equipment to an indoor location where we could expand our activities throughout the year and exhibit a wider range of emerging growing technologies.



Aquaponics is a recirculating system that combines hydroponics (growing plants in a nutrient solution without soil) and aquaculture (fish farming) to create an efficient closed loop system:

  1. We feed the fish
  2. The fish poo
  3. 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
  4. The nutrients fertilise the plants and in turn the plants purify the water
  5. The water is then pumped back into the fish tanks
