How Does Blocking Out Ultraviolet Light
Affect Plant Life?
Cool N Lite®
high tech film protects all interior
furnishings from sun damage by, among other
things, blocking out up to 99% of the
harmful ultraviolet radiation. It is true
that plant life does require chlorophyll
light absorption to activate the food
manufacturing process of photosynthesis.
However, it is the VISIBLE LIGHT wavelength
that the chlorophyll absorbs, not the
ultraviolet. Therefore, ultraviolet light is
not normally required for good plant growth.
|
In most situations, if a houseplant
is already receiving adequate light,
the use of window film will have
very little effect on it. In some
cases, new growth or flowering may
be retarded for a few days or the
plant may possibly go into a
temporary state of shock while it
adjusts to the change in the
environment. If a particular plant
normally wilts by the end of a sunny
day, window film may actually have a
very beneficial effect on that plant
by protecting it against over
exposure to sunlight and too much
heat. |
 |
Although there are some guidelines in
determining what, if any, effect window film
will have on a specific plant (for instance,
dark green plants generally need less light
than lighter colored plants), there is one
simple test which can be done prior to
installing the window film; that is, merely
move the plant to an area with less sunlight
for a few days and see how the plant reacts.
We also recommend contacting local nurseries
or agriculture agencies for advice on
whether a particular plant needs closer to
maximal or minimal light. |
