Urban Farming Goes Vertical with LEDs

We like to report on interesting applications using LEDs. This latest application we are focusing on takes LEDs and combines them with farming to leverage unique properties – temperature and wavelenghths —  of LEDs to grow more, better plants, indoors without the use of pesticides.

Chicago’s Green Sense Farms takes advantage of LEDs to make the largest indoor commercial vertical farm in the United States. According to a report in Gizmodo, Green Sense Farms recently announced two new huge climate-controlled grow rooms in its Chicago-area production warehouse. Green Sense Farms combines towering racks of vertical hydroponic systems with Philips “light recipe” LED grow lights.

Philips is building a database of ‘light recipes’ for different plant varieties since each plant has its own needs for light. A Philips Horticulture “light recipe” is an instruction based on knowledge of how to use light to grow a certain crop under certain conditions. Because LEDs produce less heat than traditional lighting, the light fixtures can be placed much closer to the crops without fear of burning them— reducing the vertical farm’s footprint and ensuring that each leaf gets the light it needs.

Using the system, Green Sense Farms is able to harvest its crops 26 times a year while using 85 percent less energy, 1/10th the amount of water, no pesticides or herbicides, and reducing the facility’s CO2 output by two tons a month. And, to make the Earth a better place, it even produces an average of 46 pounds of oxygen daily.
