you have shopped carefully, be prepared for
things to seem a bit different at first. Follow
the manufacturer’s guidelines and be patient.
[Editor’s note: LEDs Magazine also recently
published an article on horticultural lighting
specification and buying considerations —
Q: Can you give application guidelines for
UV LED, especially on cannabis?
Vaughn: Several people are asking for
guidelines, especially on cannabis. The
answer is fairly nuanced and the research is
also still being done. There are some general
best practices in terms of the dose needed to
trigger the UVR8 photoreceptor: strains that
are more or less responsive, number of hours
of exposure in a day, and when in the lifecy-
cle to apply the light. More research needs
to be done to ensure that these guidelines
are absolutely optimized. The trouble is that
any institution receiving federal funding is
legally prohibited from studying cannabis.
The real pioneers in the research here are the
growers themselves, and we love partnering
with medium-to-large-scale growers to col-
lect more data!
Q: Besides cannabis, what benefits
are there of UV-B to vegetables, herbs,
Vaughn: Edible plants have the same
photoreceptor as cannabis. Nutrients like
antioxidants and flavonoids (the things
that make plants look, smell, and taste good)
become more prevalent with UV-B expo-
sure. There is also some interesting research
showing benefits of UV-B post-harvest in
extending the shelf life of produce and erad-
icating powdery mildew.
Horticultural lighting continues to grow into its role
We’ve stated multiple times that the market for horticultural lighting is expanding
as SSL technology continues to gain acceptance by growers of all sizes (http://bit.
ly/2vKfhKI). Yet we don’t assume we know it all when it comes to such a specialized
niche, which is bringing forth new opportunities all the time. Check out the article
by Maury Wright on p. 27, for example. Wright reported on a specialty grocer that
planted its feet firmly into onsite growing operations, establishing a container farm
equipped with LED lighting that allows consumers access to super-fresh produce
such as herbs, lettuce, and other greens. New projects and installations such as these
container farms would not be possible without the right mix of science, ingenuity,
and collaboration. You will find all of the above on the menu at our second US
Horticultural Lighting Conference in Denver, CO this October. Learn more about the
