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.

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…
