One measure of how well an artificial plant light works is how well plants
grown under the grow light compare to plants grown outdoors in natural
sunlight. Does this mean the sun is the perfect plant light, and that the
artificial light that is most like sunlight is the best? Let's take a look at the
good and bad features of sunlight.
Without a doubt, the sun gives plants more useful light than any other
light source. If there's some type of light a plant needs, it can be sure to find
it in sunlight. Sunlight is the ultimate broad spectrum plant light. Yes,
sunlight is also free, so it's difficult to beat it for growing plants. Artificial
plant lighting sources vary in price, but none are as inexpensive as sunlight.
Can plants use all of the sunlight they get? Actually, no, they can't. The
reason plants have pigments to protect them from too much light is because
they can't use some of it, but it can still cause damage. The noon sun in
summer is particularly strong and damaging to plants. And not only does
this extra light cause damage directly, some of it is absorbed by plants and
converted to heat, adding stress to plants already struggling to survive in
the hot summer sunshine. Beyond one end of the visible light spectrum is
UV light. This high energy light causes sunburn in people and damages
plant cells. Sunlight contains a lot of UV. Going past the other end of the
visible spectrum we come to IR light. Infrared light also adds heat, another
source of damage and stress for plants.
All of today's conventional plant growing lights began their lives as
general purpose room lamps, used for lighting indoor spaces for people.
Because of the need for artificial grow lighting, all of these bulbs have been
modified to enhance their light output to make them better able to grow
plants. From the humble suburban incandescent bulb to the ubiquitous
fluorescent tube, and the blazingly bright high intensity discharge lamps,
makers of these modified bulbs claim their lights really "do the job" of
growing plants without sunlight. The operating cost is high, they generate a
lot of waste heat that has to be removed, and in the case of metal halide
lamps they emit a lot of UV.
New technology only recently available have allowed the creation of the
next generation of plant grow lighting- led grow lights. Targeting only
frequencies of light that plants can use, the LED Grow Master line achieves
the dream of a small, cool operating, efficient plant light.
LEDs are an entirely new light source. The qualities of the light that is
emitted from LED grow lights are different than the qualities of light from
traditional light sources. This is why the plants grown under the new light
source will also have different qualities. Plants grown under LEDs will exhibit
compact growth. The quality wavelengths emitted from the LED Grow Master
line satisfy the plants light requirements and eliminate the need to "stretch"
toward the lights.
LED plants will show no signs of heat stress. Too much heat in your
environment causes the roots to stop growing, flowers to wilt prematurely,
"sun spots" to occur, leaves droop, and reduction in chlorophyll may leave
white or brown foliage. Plants may survive for years in this stunted state but
ultimately they will die. This issue becomes extremely problematic when
growing in small areas under light sources that are sometimes 1500
degrees F. Take the rose for example- spotting and edge burning are
commonplace under the sun and traditional white light sources. Miniature
roses have been grown under LEDs with blooms that were picture perfect
and unblemished, with some varieties having flowers that lasted for months
There are other positive differences that you may notice such as
increased symmetry and deeper colors in your foliage. All of these changes
are brought about by the unique blend of wavelengths incorporated into the
LED Grow Master line of lighting. These are growth characteristics that
were previously not possible. LEDs not only grow plants- they grow them
better. Out with the old and in with the new. -AL
When we look at the way companies promote their products the norm is
to list the added features. The way to understand LEDs benefits can be
better described by the French writer Antoine de Saint-Exupery when he
wrote "Perfection is achieved not when there is nothing more to add, but
when there is nothing left to take away."
Here is what the LGM line does not have. They do not have lead or
mercury- known for their toxic effect on humans and the environment. They
do not have glass parts to break or cut. There is no UV and only trace
amounts of heat. We have taken away the high voltage that causes shock
and fire risks. We have taken away the need for ballasts and external
reflectors. LEDs emit a focused light that does not scatter around the room
like traditional light sources, eliminating wasted light that translates as white
light pollution. We have removed the high energy bills and frequent
replacements. We have eliminated the bulk.
What the LED Grow Master line represents is plant lighting in a pure
form. Light that is completely absorbed by your plants to promote healthy,
robust growth with an efficiency that is unparalleled in grow lighting.
Simplified to perfection.-AL
