LED Proven Superior to HPS for Cut Gerbera Production

LED Proven Superior to HPS for Cut Gerbera Production

Poster Session presented at American Society for Horticultural Science Annual Conference, 2015, in New Orleans, Louisiana
At higher latitudes, typically above 39 degrees, greenhouse cut flower & vegetable growers rely on supplemental lighting for production in the darker months.

HID lighting technologies are being phased out as horticultural LEDs have been proven to produce similar or better crops while also having longer lifespans, higher energy efficiencies (PAR/Watt) and can be controlled in terms of spectral distribution and intensity.

This project sought to determine the optimum light level for cut snapdragon production during the 2014-15 supplemental lighting season (ie. Nov. to Mar) at higher latitudes.
