Researchers from the University of Essex will try to grow onions outside traditional soil-based methods – inside a bright pink shipping container.
A new partnership between the university and onion supplier Stourgarden will trial the technique to explore making the onion production process more environmentally friendly.
The experiment will take place inside specially designed container farm equipped with the latest aeroponic irrigation equipment, supplied by LettUs Grow.
Prof Tracy Lawson of the University of Essex’s school of life sciences will experiment with aeroponic growing methods to grow onions in a more sustainable way, which will see them grown in an air and mist environment.
The research partnership aims to reduce the carbon footprint of the production process and speed up growth as well as prevent disease which can leave soil unusable for future crops.
Prof Lawson said the project is “extremely exciting” as it expands on the university’s ongoing research focused on manipulating light within controlled environments and vertical farms.
“We’re now channelling this expertise towards a crop with diverse growth stages, ranging from seed germination to bulb formation,” she said.
“Working directly with a local company to develop the right conditions for rapid growth demonstrated the translation aspect and potential impact of this work.”
Project lead from Stourgarden, Jonathan Bell, said the project will put the growing of onions under the microscope and allow researchers to understand more about the crop’s growth and how environmental conditions affect an onion plant.
“We will be looking to the future, and how Controlled Environment Agriculture can play a part in the supply of onions to UK consumers,” he said.

“To wholly replace traditional field production is not the aim, but there is a role for CEA to play in improving current growing and supply.
Using LettUs Grow’s ultrasonic aeroponics, plants are grown without soil and irrigated using a nutrient-dense mist.
This benefits the plant by increasing access to oxygen and boosting plant health, resulting in increased growth rates and yields.
This method is also resource efficient as it reduces use of fertiliser and water, researchers said.
Chief scientific officers and co-founder of LettUs Grow, Jack Farmer, said: “We’re thrilled to be working with both Stourgarden and the University of Essex on a project that’s at the cutting edge of innovation within our industry.
“Aeroponics is a powerful irrigation method that has the potential to be applied to a variety of crops within our diets.
“Onions are a staple crop in the UK, so we’re really excited to be exploring how aeroponics can improve the sustainability & efficiency of the growing process.
The project is being jointly funded by grants from Innovate UK and the Biotechnology and Biological Sciences Research Council.
Innovation partnerships manager at the University of Essex, Holly Leonard, said: “We’re delighted to be working with local partners, Stourgarden on this project.
“Their status as the UK’s largest producer of onions means this project has the potential to positively impact food production in the UK.
“Not only is the project going to advance scientific understanding through research, if we can prove the commercial case for protected growing of traditional field crops such as onions, there is potential to increase UK food security by extending growing seasons and reducing reliance on imports.”
