With America quickly noticing how much power the cannabis industry draws from the grid (as high as one percent of the country’s total electricity usage), the hunt is on for the most efficient grow ...

LEDs are capable of replacing HPS for supplemental lighting for cut gerbera production during darker periods. In Canada, as in other higher latitudes, there is not enough natural light for production ...

Hydroponically grown tomato plants were subjected to three light intensities at three red-to-blue ratio levels and compared to high-pressure sodium, red LED light, a 50:50 LED:HPS mixture, and no ...

UK LED maker Plessey has proved LED lighting can increase crop yield, in a trial where it was added to an existing high-pressure sodium (HPS) light installation. The seven-month trial, managed by ...

In Canada, as in other higher latitudes, there is not enough natural light for production of many greenhouse commodities during the darker months of the year. In these regions, it is necessary for ...

“Global efforts to phase-out the use of HPS continue to be met with a resistance to using white LED replacements. Due to this lack of a viable and sustainable alternative, HPS have remained exempt ...

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, Troy, NY, published a new report on the energy and economic performance of LED horticultural luminaires. The research team found ...

HPS, or high-pressure sodium, bulbs are one of the most popular HID (high-intensity discharge) lamps in use today. Heavier in the orange-to-red wavelengths, HPS bulbs provide excellent spectrum for ...
