Video of the Week: A Showcase of Greenhouse Lighting Technology

Each week, Greenhouse Grower highlights a video that shines a spotlight on the controlled-environment industry, from crop protection advice to insider views on plant production at greenhouse operations across the country. Have you recently produced a video you want us to highlight? If so, please send a link to Greenhouse Grower Senior Editor Brian Sparks at [email protected].

The Greenhouse Lighting and Systems Engineering (GLASE) consortium is a public-private institution working at the leading edge of LED systems engineering, plant photobiology and physiology, and greenhouse environmental controls (learn more here). In a recent webinar, GLASE principal investigators showcase a selection of the research, projects, and programs of GLASE.

Timothy Shelford from Rutgers University compares and contrasts the spectral output and performance of different types of horticultural lighting fixtures from different manufacturers with a focus on efficacy and the new ePAR range. Elsebeth Kolmos from Rensselaer Polytechnic Institute discusses the role of blue spectral quality in the growth and development of lettuce and tomato under sole source lighting. Neil Mattson from Cornell University discusses how the light intensity of many commercial LEDs can be adjusted in real-time, presenting results from Cornell trials testing a dimmable LED lighting control strategy for greenhouse lettuce, strawberry, and tomato crops.
