This study sought to determine the optimum light level for cut “Ultima” gerbera production during the 2015-16 supplemental lighting season (ie. Nov. to Mar) at higher latitudes. We compared stem length, number of leaves, times to first flower, time to harvest, fresh mass of harvested flower, flower diameter, and stem length under 40, 75, 135, 170 & 180 μmol·m-2·s-1 of LED light.
