Sinusoidal LED Lights Boost Rocket Growth and Cut Energy Costs

A recent study published in Frontiers in Plant Science explores the impact of light intensity regimes on the photosynthetic efficiency and biomass production of crop plants in Controlled Environmental Agricultural (CEA) systems. Researchers from the University of Essex demonstrate that a sinusoidal light regime, as opposed to the traditional square wave methodology, can enhance the edible biomass of rocket by approximately 20% while utilizing 0.6% less electricity. This approach, which maintains higher photosynthetic rates later into the photoperiod, optimizes energy use and improves the overall profitability of indoor farming. The findings suggest that capping maximum light intensity at 250 μmol m^-2 s^-1 yields superior electron transfer rates and reduced photoprotective responses, ultimately leading to a greater Daily Photochemical Integral (DPI). The finalized article will be publicly available soon.
