Precision Control of Supplemental Lighting

Supplemental lighting is important in facilitating winter-time greenhouse crop production in many areas of the United States. LED fixtures are becoming increasingly popular due to their higher efficacy and longer lifespan, as compared to HPS... more »

Light Spectrum for Different Applications

There are several terms used to describe the color, or spectral distribution of light, including light quality, spectral quality, light spectrum and photon spectrum. These terms describe the relative quantities of different wavebands of light,... more »

Consider the Photosynthetic Benefits of Far-Red Radiation

A bumper crop starts with great seedlings. As a grower, it makes sense to supply supplemental lighting to the propagation table. Plants are densely spaced at this time so the money you spend on lighting... more »

Increasing the Daily Light Integral

The daily light integral (DLI) refers to the cumulative amount of light received per day. More technically, the DLI is the number of moles (mol) of photons with wavelengths between 400 and 700 nm that... more »

Virtual Plant Lighting Short Course to Take Place in October

The first annual virtual Plant Lighting Short Course will take place this October and November. The short course is being presented by GLASE (Greenhouse Lighting & Systems Engineering), OptimIA and LAMP (Lighting Approaches to Maximize... more »

LEDs: More than μmol×J–1

Light-emitting diodes (LEDs) are known for their efficiency at converting electricity into light. For most plant applications, we are primarily interested in how much of the light emitted is within the photosynthetically active waveband (PAR),... more »

GLASE Webinar to Highlight CEA Research Programs

On June 24, GLASE (Greenhouse Lighting & Systems Engineering) will host a roundtable with six young CEA professors as part of its webinar series. During this webinar, followed by a Q&A section, the audience will... more »

Fluence, Prospiant Team Up on Lighting Technology

Fluence by OSRAM, a global provider of energy-efficient LED lighting solutions for horticulture, commercial cannabis and food production, and Prospiant, a Cincinnati, Ohio-based provider of complete ecosystems for controlled environment agriculture (CEA), recently announced that... more »

Not All DLIs Are the Same

Sunlight gets scarce during the winter season. However, many plants are grown in winter for sale during the busy spring season. Electric lights, either HPS or LEDs, may be needed to supplement the light that... more »

How LED Lighting from Current Is Feeding Thousands in Texas

{Sponsored} Located at the State Fair of Texas®, Big Tex Urban Farms is part innovation lab, part production facility and fully on a mission to grow fresh produce for food-desert communities. A food-desert area is... more »
