LIGHT MOVERS
Outdoors, plants receive light from
many directions. Over the course of the day
the sun bathes plants in light starting in the
east and travelling west. Leaves shaded
during part of the day are under full sun at
other times.
Indoors, using a stationary light, some
plant parts are always shaded while others
are always lit. With a light in the center of
the garden, plants closer to the source
receive brighter light than those at the
periphery.
Reflectors with different shapes
distribute light in varying patterns. A good
quality reflector will spread the light evenly
over the garden. Still, a light coming from a
single stationary source leaves some areas
in permanent shadow.
Light movers were invented to solve
these problems. The movers carry the lamp
over a fixed course so that entire the
garden comes directly under the light part
of the time. These units are manufactured
by a number of suppliers and use several
innovative techniques to move the lamps.
Some of them move the lamps quickly, so
that the light passes over the garden in less
than a minute. Other movers take 40
minutes to traverse the course. Both types
improve light distribution in the garden. As
a result, the plants grow at an even rate.
Since the plants are not stretching in one
direction to the light, they grow straighter,
