LEDs shine in bedding plant production study
Date:7/21/2014

der 85:15 red:blue LEDs compared with those grown under high-pressure sodium lamps. Stem caliper of Antirrhinum, Pelargonium, and Tagetes was 16%, 8%, and 13% larger, respectively, for seedlings grown under the 85:15 red:blue LEDs compared with seedlings grown under HPS lamps. The quality index was significantly higher for Petunia, Salvia, and Viola under 85:15, 70:30, and 100:0 red:blue LEDs than under HPS lamps, respectively. Overall, the results indicate that seedling quality for the majority of the species tested under supplemental light LEDs providing both red and blue light was similar or higher than those grown under high-pressure sodium lamps.

"Our results indicate that providing supplemental lighting from LEDs or high-pressure sodium lamps has a positive influence on seedling root dry mass, height, and stem caliper leading to high-quality bedding plant seedlings when solar light is limited," Lopez and Randall noted. "A light ratio of 85:15 red:blue light could be a good combination for greenhouse LED supplemental lighting of bedding plant plugs. However, it is important to remember that although blue LEDs have a higher electrical conversion efficiency compared with red LEDs, blue light is a higher energy light, which increases energy consumption as higher proportions of blue are used."
