Light Science Technologies was founded in September 2019 and facilitates the Company’s highly prospective Controlled Environment  Agriculture (CEA) operations. The Group’s state-of-the-art laboratory facilities in Derby, UK, enable the Group to design, and, in time, test and provide innovative CEA products and services.


Light Science Technologies offers integrated, cost-saving and sustainable CEA solutions to crop growers, with a focus on the indoor, vertical and medicinal farming markets, which is expected to be the major growth area for the Group going forwards in light of the market landscape and in view of competing offerings currently in the marketplace.


Light Science Technologies’ all-in-one CEA solution includes analysing customers’ crop growing requirements to provide bespoke, low-energy products, which subsequently monitor the key growth factors of plant life (namely air speed, carbon dioxide levels, humidity, light, oxygen, soil, temperature and water pH levels) in order to maintain optimal growing conditions, maximise crop yields and minimise resource usage.
