When growing plants indoors, light is a crucial factor in the success of your operation. LED grow lights have gained significant popularity over the last few years because they use less energy, which means lower utility bills for the avid horticulturalist. Before you set out to buy an LED grow light system, however, you must first consider the colors you want to use.
Grow lights come in a variety of color temperatures, each of which will aid in the growth of your plants. Experts believe that certain colors work better than others in encouraging the growth of plants, though, so it pays to do your research. First determine which colors might perform best based on the information available, then test those theories in your own work. The type and size of the plant as well as the atmosphere in your own home or work space will influence the performance of different light temperatures.
A study conducted by Nabesei Co Ltd tested the performance of three colors in growing plants: pink, blue, and pink. At the end of their experiment, they determined that plants raised under pink grow lights grew not only to a larger size, but also faster than the plants raised under the other colored lights. The pink LED grow light also seemed to produce fuller leaves than the blue and red lights.
This does not mean that a pink LED grow light is the perfect choice for your growing endeavors. Several factors can influence color temperatures, including ambient light in the room and any filters between the light source and the plant. For example, if you grow your plants in a terrarium, the color and composition of the glass will influence the quality of light absorbed by the plants.
Blue and red lights are frequently used in indoor growing systems because they are widely available and because many people have enjoyed success with those colors. Photosynthesis charts suggest that blue and red lights encourage peak absorption. For example, a Colorado University study determined that plants grown with blue and violet lights performed best and that those grown with orange and red lights were close runners up. The same study resulted in the poorest growth results in plants grown under green and yellow lights.
Keep in mind that an LED grow light might have a different impact on a flowering plant than on one that bears fruit. Different types of plants absorb and process light differently; consequently, you might have different results depending on the species of plant. The only sure way to determine what works best in your operation is to test different colors of LED grow light and draw conclusions from what you observe.
It is also important to remember that experiments and tests with other types of lights, including fluorescents, do not necessarily translate to the use of an LED grow light. This is because LEDs are used differently in practice because they give off less heat and use less energy. You do not have to change LEDs as often as you do other types of bulbs, and you can safely place them closer to the plants. This might have a tremendous impact on the performance of plants between different types of lights.
The color temperature of a grow light is not as important as the care the plant receives. Focus on developing a well-rounded system for caring for your plants, from food and water to air temperature and light intensity. Try out different colors of LED grow lights so you can evaluate how they work over time. If one does not perform the way you expected, move on to something else. Before long, you will have developed your own personal system for producing the healthiest plants.
