The challenge
The ultimate vision or goal is the creation of a new breed of entrepreneurial growers keen to develop vertical farms in the urban environment both in the UK and overseas where environmental and social challenges are perhaps even more acute. STC anticipates that there remains considerable scope for further advances in LED and PV technology in the future which will further enhance the potential of the technology. This technology will bring a much more environmentally- friendly and cost effective way of providing fresh food for urban areas. The horizontal developed technologies can be made available to industrial and agricultural users.The solution
The LED4CROPS facility is housed within a 200 m 2 building and has over 40 benches with LED lights in a multi-tier array. This all to enable light spectrum adjustment andflexibility, for growing a range of low level crops such as herbs, leafy salads, flowers, strawberries and plants in propagation. The facilities are divided into three primary areas:
- 100% research modules in order to explore light recipes;
- a semi-flexible space containing both research (FR) and
production modules (DRB); - an urban farming section fitted with production modules (DRB).
There is a similar sized glasshouse alongside for comparison trialing. In addition, there is a smaller experimental area dedicated to look at
novel approaches to the use of LED lights in the horticulturalsector. CambridgeHOK, certified UK partner for Philips Lighting, constructed and monitored all the installation and control equipment for the LED lights. They also brought many years of experience to the design of the production equipment and structures. Tim Haworth, their general manager said ‘We at CambridgeHOK are very excited to be involved in this project as we truly believe that LEDs will become another significant tool in the growers armory. For the first time we have the ability to offer growers practical technical solutions that have a direct impact on plant physiology, in ways that can be monitored and measured.
Benefits
As LED technology progresses, the potential benefits in terms of advancing vertical farming are tremendous. STC science director Dr Martin McPherson is enthusiastic: ‘LED technology opens the door to the concept of urban farming. You can grow crops in multi-storey warehouses, close to point of consumption’. LEDs will offer growers great flexibility, he adds. ‘You can schedule the crops. If you want to bring them on, you can do so. If you want to slow them down, you can reduce power.’ According to his colleague, STC CEO Graham Ward, the prospects for growers are bright: ‘A normal lettuce grower can produce five crops a year. With this system, we can grow fifteen’.For more information:
