AeroFarms is transforming the concept of a traditional, sprawling, outdoor field of greens into an efficient, IoT-controlled, indoor, vertical grow house. Owned by Dream Holdings and based in Newark, NJ, AeroFarms aims to revolutionize how we grow produce such as kale, arugula and watercress. This alternative approach, called vertical farming, combines data science with horticulture and involves growing produce indoors, on shelves stacked seven levels high, without soil or sun but with a megadose of LED lighting and automation technology.
Using remote monitoring and controls, AeroFarms plant scientists monitor more than 130,000 data points to create what the company calls a “superior and consistent result.” As described by CEO David Rosenberg, “AeroFarms is a farming company, but we’re also a technology company. There are thousands of sensors in our warehouse, taking hundreds of thousands of data points. The details matter, and the pennies matter. So we’re trying to understand how to optimize yield, and how we can stress a plant in the right way.”
The technology used to grow the produce is known as aeroponics. With aeroponics, plants are grown through a reusable fabric, removing the need for soil. There is no sunlight, and less water is used compared to conventional farming. Plants are misted from below and provided with a nutrient rich solution that encourages growth.
The use of specially engineered LED lights allows scientists to control different aspects of the plant, such as size and flavor, along with smart nutrition, which gives scientists the ability to monitor all the macro- and micronutrients the plants require. AeroFarms plant engineers note that they can take the exact same seed from the field and grow it in half the time as a traditional field farmer. This leads to 390 times more productivity per square foot than a commercial field farm.
Healthy Food Produced Close to Home
The aim for companies such as AeroFarms is to provide locally grown produce at a more affordable price. Another goal is to grow produce in metro areas that would not otherwise be able to accommodate traditional farming methods.
“Cities have a lot of mouths to feed. We have population growth, urbanization, and we need better ways to feed humanity that are sensitive to the environment," said Rosenberg in a recent statement. “Vertical farms are one of many solutions."
A Growing Market for Vertical Farms
According to Global Market Insights, the vertical farming market is expected to generate a sizable revenue over the next seven years. A recent report from GMI stated that vertical farming market size is expected to cross $13 billion by 2024, with a striking CAGR of 27 percent over 2017-2024, having had a base valuation of $2 billion in 2017. Currently, this type of farming is most prevalent in the United States and China. During the next few years, Belgium, UK, Netherlands and Germany are slated to be major revenue contributors.
With the elimination of seasonal crops or run-offs, crop spoilage is no longer an issue in an indoor farm. This combined with decreased transportation costs is fueling the expansion of the vertical farming industry.
IoT Tools Measure Plant Stress
Recently, Dell joined forces with AeroFarms to focus on how IoT and data science can help maximize the growth of greens.
Stressing the plants drives tastes and textures, from temperature changes to humidity to PH, according to Rosenberg. With the Dell team, AeroFarms is capturing all this information. He notes that “they asked us questions that we weren’t asking ourselves, such as, ‘what information needs to go to which people, and at what time in the growing cycle is it valuable?’”
With Dell’s new distributed core IoT strategy, AeroFarms can improve its architecture and reduce costs, leading to better yields and further enhancements in vertical farming technology.
