GLASE - Free Webinar Series - July 25, 2019 - Supplemental Greenhouse Lighting During Propagation
Date: July 25, 2019
Time: 2-3 p.m. EST
Presented by: Erik Runkle and Roberto Lopez
Light is the driving energy source for photosynthesis and carbohydrate accumulation in plants. During propagation cuttings and seedlings require a minimum quantity of light to provide the energy for root initiation and development. Light intensities below this minimum result in little or no root development, leading to a delayed crop or rooting failure. Conversely, too much light can bleach leaves and reduce root formation due to excessive stress on the cuttings.
Find out how to properly manage supplemental greenhouse lighting during propagation with Erik Runkle and Roberto Lopez from Michigan State University.

Roberto Lopez
Assistant Professor @Michigan State University
Roberto Lopez earned his master’s degree in 2003 and PhD in 2007 from Michigan State. From 2008 until 2016, he was assistant and then associate professor in horticulture and landscape architecture at Purdue University.
His research focuses on energy-efficient propagation and production of floriculture crops with an emphasis on lighting and temperature management. By controlling environmental factors such as light, temperature, and carbon dioxide, Roberto has been able to influence crop timing, quality, flavor, nutrition, and color in many crops.
His lab is especially focused on light-emitting diodes (LEDs) and recently developed best-practice strategies for LED implementation in greenhouse and indoor sole-source lighting situations.
Erik Runkle
Professor @Michigan State University
Erik Runkle Ph.D, is a professor and extension specialist in the Department of Horticulture at Michigan State University. Erik obtained a B.S. in ornamental horticulture from the University of Illinois and an M.S. and Ph.D. in horticulture at Michigan State University.
Since he joining the Michigan State faculty in 2001, Erik and his graduate research team have performed numerous practical experiments in controlled environments to determine the effects of light, temperature, and other environmental factors on plant growth and development. Experiments have been performed on a wide range of herbaceous specialty crops including leafy greens and ornamentals. Erik recently developed the Controlled-Environment Lighting Laboratory to better understand how the light spectrum can be manipulated to produce crops with desired attributes.
To date, Erik has co-edited six books and authored 14 book chapters, nearly 100 papers in scientific journals, and over 250 articles in trade magazines.
