Considerations for greenhouse lighting with LEDs

The UNH Cooperative Extension Landscape and Greenhouse Team will host a free webinar on “Lighting approaches to maximize profit (LAMP): considerations for greenhouse lighting with LEDs” from 7-8 p.m. June 29. The guest speaker will be the Neil Mattson, Associate professor and greenhouse extension specialist, Cornell University

Supplemental lighting is often needed for on-time production of high-quality crops. But it can also be expensive. Determining the return on investment of supplemental lighting can be complicated, because it depends on how the lights are used, the cost of electricity, crop responses to the supplemental light, and the value of the crop. Enter project LAMP, recently funded from the USDA Specialty Crops Research Initiative. Neil will discuss tools for how to determine how many lights (LED or HPS) are needed, what the capital and operating expenses are, and how to control those lights to optimize growth and quality of vegetables and ornamentals. Neil will end the webinar presenting project results showing effects of specialty lighting applications (such as far-red light, and adjusting red:blue ratio).

Webinar is free; registration is required.
