PAR

Spectrum Technologies, Inc., expands their broad product offeringwith the release of the LightScout® Quantum PAR/DLI Light Meter. By using the Quantum PAR/DLI Light Meter, horticulturalists no longer have to guess how much light their plants are receiving. Because the amount of light delivered to plants,…

Plants can perceive and react to light across a wide spectrum. New research from Prof. Nitzan Shabek’s laboratory in the Department of Plant Biology, College of Biological Sciences shows how plants can respond to blue light in particular. “Plants can see much better than we can,” Shabek said. Plants…

The plant uses barely fifty per cent of the sun’s radiation energy for photosynthesis. This part of sunlight is called PAR-light. Within this range all the wavelengths have a function, contrary to what was once thought. Plants use light for two things: photosynthesis and photomorphogenesis (control of…

Plants have evolved around the sun as their natural source of energy. This is important because the sun is at an infinite distance away, with a predictable cycle over the course of days and seasons. The more light a plant receives, the more it will grow and thrive. In the natural environment, when a…

Growers generally have two options when it comes to horticultural LED spectrums – “full spectrum” or “broad-spectrum”, which appears as white light; and “red/blue spectrum”, which can appear as purple or pink light.    

In June team AuTomatoes won the second edition of Wageningen University’s Autonomous Greenhouse Challenge. There was no discussion about the team’s win, they scored highest on all three grading criteria, making them the absolute winner. In their strategy the team applied the principles of Plant…

There has been some discussion online and in presentations recently about the issue of photosynthetic photon flux. The argument goes as follows: Photosynthetically Active Radiation (PAR) is somewhat arbitrarily defined as optical radiation within the spectral range of 400 nm to 700 nm. Exposing plants to…
