PAR Light Quality LEDs & HID: Plant Grow Light Basics -101 (pt 1)
Selecting artificial grow lights can require quite a bit of research and sometimes growers are faced with conflicting information. How can we select the best lights for our application? Should we rely on weed growing forums for all of the facts? What about university level research? This is the 1st video of a multi-part series that is intended to explain many basic principles surrounding plant lighting and its application in horticulture.
The focus of this video is all about Light Quality. What effect do different light wavelengths have on plants and their development? Do plants need UV light? How does Far Red light effect plant growth? Do plants use green light or is green light wasted energy? These questions are answered, along with scientific research that you can read more about, depending on your level of interest.

We'll take a look at the visible light spectrum (a portion of the electromagnetic spectrum). We'll see how color wavelengths are measured in nanometers. What is PAR light (Photosynthetically Active Radiation)? Various light types have unique spectral profiles, as measured by a spectrometer. We'll quickly look at a few charts from LEDs, fluorescents, high-pressure sodiums and metal halides. Many of these can be rated on the Kelvin color temperature scale, which is discussed as well.
When considering LED vs HID, the spectral composition can be a major factor. Some LEDs have a few limited color bands (in blue and red ranges). Some include a "full spectrum" light source. How do they make white light from LEDs? One common approach, shown in this video, is to use a phosphor coating.
This is the basics of plant lighting and grow lights. It is intended to benefit a broad audience, from home gardeners, to greenhouse growers, to vertical farmers and even "medical" growers. But Light Quality is only one of many factors that are worth consideration.
In future videos we'll explore Light Intensity and how horticulturists measure it. We'll look at PPFD vs Lumens. Then we'll examine differences in light efficiency. Finally, we'll consider various form factors and their pros and cons.
