Wageningen University And Research Center (WUR) in the Netherlands collaborated with Fluence and greenhouse agriculture consultant Vortus to release preliminary results of a cultivation experiment that analyzed the feasibility of Fluence's full-spectrum LED lighting solution Sex.
The data shows that compared with high-pressure sodium lamp greenhouse lighting fixtures, for certain tomato varieties, using Fluence's PhysioSpec Greenhouse™ spectrum can increase tomato yield by 11% and have higher energy efficiency.
The research was conducted on Tomagino and Merlice tomato varieties. Dr. Ep Heuvelink of WUR and his team compared the effects of Fluence's PhysioSpec Greenhouse with a high-pressure sodium lamp provided by a recognized supplier.
Barend Lobker, the boss of Vortus, said that many growers currently use high-pressure sodium lamp technology as the only light source to supplement greenhouse lighting, and WUR's test proves that this is not the case. Growers are not sure whether LED can cultivate crops as effectively, so they have been reluctant to switch to LED lighting. The WUR test this time eliminated any doubts about the performance of full-spectrum LEDs.
Haris Ouzounis, Fluence's gardening service expert and senior photobiologist, said that this is a very exciting result for the application of full-spectrum LED technology in greenhouse tomato production. The test showed that even without any environmental optimization for LED solutions, full-spectrum LEDs can also match the needs of commercial growers, and their effects even surpass traditional lighting fixtures.
