Light movers, although often overlooked by the hobbyist, give expert growers their edge by increasing the grow area with just a few extra watts. Stationary lights can create shading under the canopy, but moving grow lights back and forth allows a full spectrum of light to penetrate the plants underlying regions of the canopy, eliminating permanent shadow areas.
The angle of light also continuously changes, allowing increased light energy to reach a larger leaf surface area resulting in a healthy, natural and an even growth profile. Also as the grow light is constantly moving, plants can safely grow closer without risking heat damage. All this adds up to more growth and improved light spread, without a jump in energy costs. Could your indoor garden be without a light mover?
