Fresh Herbs And Vegetables
Luke Ellis, from Sheffield, grows his produce at Kelham Island using organic soil and food created from waste products and without natural light.
He said it might sound like science fiction, but the unusual farming method has the potential to address food shortages and climate change.
The business already sells produce to restaurants and direct to customers.
Mr. Ellis first became interested in hydroponics technology six years ago but felt it was not as sustainable as it could be with most companies using high-tech, state-of-the-art equipment with a high start-up cost.
To address that he decided to create a bioponic farm, an organic form of hydroponics.
"Bioponic vertical farming may sound like something straight out of the world of science fiction, but it is a sector which holds a lot of potential for growth," he said.

The company uses waste materials, such as paper, card and food scraps, to create its own soil and the run-off from those systems is not wasted either.
"We make our own plant food, which means we don't ever pour anything away," said Mr Ellis.
The plants are grown under electric lights which, he added, offer advantages.
"Artificial light can be better than natural light because we can control the flavour of the food and control the growth rate."

Mr. Ellis said he hoped the business, which opened in December 2020, would inspire others to help build a "greener, more sustainable society".
"It's super fast to grow, we use recyclable materials, it's 100% organic and it's very efficient," he added.

Cambridge Engineers Unveil Digital Twin To Support The ‘Future of Farming’
Hydroponic farming challenges traditional methods in favour of soil-less, water-based farming processes. To ensure the ongoing operational success of farms such as these, Cambridge engineers have developed a virtual forecasting model to provide bespoke feedback to farmers
Hydroponic farming challenges traditional methods in favour of soil-less, water-based farming processes. To ensure the ongoing operational success of farms such as these, Cambridge engineers have developed a virtual forecasting model to provide bespoke feedback to farmers.
The researchers show how a Digital Twin can faithfully represent the reality of an environment – in this case a unique hydroponic farm in London (Growing Underground) – through real-time data analytics and modelling, including the integration of a tailored temperature forecasting model to assist farmers’ decision-making. Their findings are published in the Cambridge University Press journal Data-Centric Engineering.
With hydroponic farming – often termed the ‘future of farming’ – on the rise across the UK and globally, the researchers believe that Digital Twins are particularly suited to bespoke environments such as these, providing an opportunity to move away from a ‘one size fits all’ approach, in favour of a virtual representation that can cater to a farm’s changing operational conditions.
Growing Underground is situated in repurposed WW2 air raid shelters that are 33 metres below the streets in Clapham, London. Crops are grown year-round in a pesticide-free environment controlled by LED lights, ventilation, dehumidifiers, and irrigation tanks. The farm grows 12 times more per unit area than traditional greenhouse farming in the UK but also consumes four times more energy per unit area. Therefore, finding ways to minimise the energy use while maximising crop growth and maintaining optimal growing conditions is key to the ongoing operational success of this farm and others like it.
The researchers show how the development of a Digital Twin can be useful not only for informing farm operators in real time, but it can also help them to prepare for the future. Data creation, data analysis and data-centric modelling were all required to create the Digital Twin for Growing Underground. This involved an extensive monitoring system that combined wireless sensors with manual data records to track the observable environmental conditions in the underground farm; identifying the influencing variables on energy use and crop yield; and helping to forecast potential future operational scenarios, as well as providing feedback on the influence of recent events on the farm environment.
The Digital Twin can also provide enhanced data to help assist farmers in the decision-making process, offering advice specific to the needs of the farm. For example, the researchers identified that the LED lights have the greatest influence on daily temperature fluctuations in the farm and so they created a bespoke temperature forecasting model that predicts extreme temperatures. This model can be integrated into the Digital Twin and it is easy to implement, making use of temperature and energy meter readings. It is also flexible to the addition of more data as it becomes available and provides feedback on operational changes that can reduce energy use and control the farm environment more effectively.

Dr Ruchi Choudhary, Reader in Architectural Engineering, said: “As we move towards more innovative agricultural practices, such as hydroponic farming, there is a greater need for an intelligent Digital Twin over a simple monitoring system. The Digital Twin we have developed for the unique hydroponic farm, Growing Underground, can observe, process, and interpret farm data (i.e. energy, weather, live sensor data and manual records) that leads to tangible outcomes. This can include warnings (i.e. concerning temperature fluctuations that require changes to ventilation, heat, light); causal relationships (resource use efficiency, crop health); operational suggestions (using a forecasting model); and a prediction of future conditions."
Melanie Jans-Singh, lead author and Ph.D. student, added: “In essence, our Digital Twin becomes the urban-integrated farm operator’s 24/7 smart ‘companion’, a living digital reference, providing bespoke feedback on the effectiveness of the measures taken in real-time. This is in addition to longer-term forecasting and informed decision-making, with control processes that are robust to human error. It is suited to mid to large scale processes, often seen in civil engineering, where sensor maintenance will also be an issue.”

Future of Agriculture Grows Under Seoul’s Subway Stations
The Seoul Metropolitan Government, Seoul Metro, and the agriculture company Farm8 have come together for this project
Experts introduce the facility during the opening showcase of Metro Farm at Sangdo Station in September 2019. (Farm8)
Walking down the stairs from exit No. 2 of Sangdo Station in southwestern Seoul, its not easy to miss a white and green signboard that reads “METRO Farm.”
A method of what‘s known as “smart farming,” Metro Farms can create nature-friendly environments while being located inside urban subway stations, using AI and Internet of Things (IoT) technologies.
Sangdo Station’s exit No. 2 was originally left unattended, merely serving its purpose as a meet-up plaza. Since September 2019, the space is now a farm full of sprouts and herbs.
The 394-square-meter cultivation facility is a complex space consisting of an “Auto-Farm,“ where robots manage basic sowing and harvesting, a “Farm Cafe,” which sells fresh salad and juice, made from crops harvested on the same day, and “FarmX,” a zone where visitors can learn about the future of agriculture.
The Seoul Metropolitan Government, Seoul Metro, and the agriculture company Farm8 have come together for this project. In 2004, Farm8 started out as a firm that produced and distributed vegetable salads. Over time, the company shifted gears to conduct research on indoor farming as a method of sustainable agriculture that can operate regardless of weather conditions and has succeeded in developing high-tech distribution centers.
The three organizations worked together to enhance the ecological sensitivity of Seoul as a city, and allow young people living in urban districts to experience agriculture with their own eyes.

“We tried our best to make Metro Farms a lively experience, where visitors can get a grasp of its possibilities and to be recognized a place where technology meets nature,” senior manager of Farm8 Yeo Chan-dong told The Korea Herald.
Since the very first showcase of Metro Farm at Dapsimni Station in eastern Seoul in May 2019, Yeo explained that they have made progress in creating urban agricultural jobs and expanded Metro Farms across the city.
An average of 7.5 million people take the subway each day in Seoul, according to Seoul Metro. This means that passersby will naturally encounter Metro Farms on their way to work, home or to meet family and friends.
“Our assignment for the new year is to make Metro Farms more popular and sustainable,” Yeo spoke with confidence, “In other words, not only presenting the experience but eventually making a system for the crops grown to be made a competitive quality to suit the needs of the public.”
