Speaker: Jennifer Boldt, Research Horticulturist at USDA Agricultural Research Service

Session Title:  Lighting and CO2 Management and Optimization

Sunday, July 11  11:00 AM - 11:45 AM

Description: Plants need light and carbon dioxide (CO2). Yet how often do you measure, manage, and optimize these production inputs in your greenhouse? We’ll explore plant responses to light and CO2, identify strategies for supplying supplemental light and CO2, and discuss scenarios when it would make sense to provide supplemental light and/or supplemental CO2 in your greenhouse. 

Level: All Audiences           Type: Research

Session Speakers:

Jennifer Boldt, Research Horticulturist at USDA Agricultural Research Service
Joshua Craver, Assistant Professor at Colorado State University

Jennifer Boldt, 

Research Horticulturist at USDA Agricultural Research Service 

Jennifer Boldt, Ph.D., Research Horticulturist, Greenhouse Production Research Group (GPRG), Agricultural Research Service (ARS), United States Department of Agriculture (USDA), Toledo, OH. Dr. Jennifer Boldt has over 25 years of experience in commercial greenhouse production, garden trial management and research. She and her ARS colleagues investigates production technologies, diseases, pests and abiotic stresses for greenhouse ornamental industries. Their goal is to transfer developed technologies to the industry through partnerships with state extension services and direct stakeholder activities. For Project LAMP, Dr. Boldt will update Virtual Grower software with the help of our research team. Virtual Grower allows greenhouse growers to estimate heating and lighting needs, predict crop growth, assist in scheduling, make real-time predictions of energy use, and assess supplemental lighting impacts on plant growth and development. Through Project LAMP, she will expand the lighting section of the software by integrating Project LAMP results to allow growers and our research teams to simulate specific lighting scenarios for different greenhouse operations to estimate the economics of supplemental lighting.
