In growing plants in business or home, light along with temperature and humidity, can be controlled and thus become a tool for producing luxuriant healthy growth.
With fluorescent light you can give plants just the illumination they need all the time, no matter what the weather outside.
Plants grown under two 40-watt, 48- inch fluorescent bulbs with a reflector may receive up to 1,000 foot-candles of light, depending upon their distance from the source.
Keep in mind that light intensity is not the same all along the tube. The most light is right in the middle, the least at the ends. Therefore, a light -loving plant, like the geranium, can be placed on a little block if necessary to make its tip just clear the light in the middle of the tube. Start cuttings, which are satisfied with little light, right in the peat moss at the ends of the tubes.
Fluorescent lights are better for growing plants than the incandescent ones, which give out a light in which red rays predominate.
These rays are good for top growth and seed germination. Fluorescent lights are predominately blue which helps produce flowers, develop roots and deepen color of the leaves. They are cool and can’t overheat plants.
