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.

About Beth

It seems like LEDs are in everything these days – backlighting everything from your mobile phone, Apple iPad and flat screen HDTV to traffic lights, light bulbs and even the kitchen sink. But, making LEDs is a complex process that begins with the creation of sapphire. Not the pretty blue gemstone, but large commercial crystals that can weigh as much as 400 lbs. Once these large sapphire crystals are grown into boules and cooled, they’re cut into cores, cut further into flat circular wafers, polished and then used to grow LEDs. About 85 percent of HB-LEDs (high brightness) are grown on sapphire. There’s not that much information out there about the process. This blog is meant to shed some light (excuse the pun) on sapphire, LEDs and the industry that is devoted to making our lives just a little brighter. In the months ahead, we’ll tackle some topics that will help you understand a little more about sapphire and LED industry. Here’s a sample of what we’ll cover in the coming months: • Growing sapphire • For a wafer, size matters • Quality - When sapphire wafers go bad • LED light bulbs • Market & myths • Interviews with industry shining stars • Reports from industry events • Current events in perspective Please join us each week to learn more about sapphire and the LED market. We look forward to seeing you.
