Manipulating Light Quality and Duration to Improve the Greenhouse Production of Specialty Cut Flowers

March 7, 2023 @ 8:00 pm - 9:00 pm EST

Part of the ASCFG Research and the Flower Farmer Webinar Series! 

Dr. Roberto Lopez, Michigan State University
Caleb Spall, Michigan State University

Event Details

A recent recipient of an ASCFG Grant, this project seeks to determine the ideal lighting conditions, in both the intensity and duration of lights, for growing flowers in greenhouse settings. In response to the growing market for specialty cut flowers throughout North America, crop growth and management in greenhouses can help meet the year-round demand for flowers. Dr. Lopez and Mr. Spall will discuss the exciting outcomes of their research and answer questions from audience members.

Presenter Biography

Dr. Roberto Lopez

Dr. Roberto Lopez is an associate professor and controlled environment/floriculture extension specialist with a 45% research, 30% teaching, and 25% extension appointment in the Department of Horticulture at Michigan State University. His research focuses on propagation and production of young and finish plants (floriculture, leafy green, and culinary herb crops) in greenhouses, growth rooms/containers, warehouse-based plant factories, and vertical farms. The primary objective of his research is to determine how light (quantity, quality, and duration), substrate and air temperature, and carbon dioxide in controlled-environment agriculture (CEA) production influences crop timing, rooting, yield, quality, flavor, nutrition, and subsequent performance.

About the Research and the Flower Farmer Webinar Series 

The goal of this webinar series is to connect ASCFG members with the latest research in cut flowers and to inspire new ideas for crop, farm, and business management. During these online events, recent recipients of the Research Foundation’s Competitive Grants will share synopses of their research, along with the exciting applications of the results, before a short Q and A session with attendees.

Can’t attend a presentation? Don’t worry – the webinar will be recorded and be accessible in the ASCFG Members Only portal after the event.

Zoom instructions will be emailed to members on the day of the event. A recording of this session will be archived in Members Only.
