Although there is a natural growth cycle for every plant, the vegetative and flowering stages of growth are directly influenced by light. Artificial light conditions allow you to manipulate the growing environment and produce at a more rapid pace. Improper light exposure can result in weak, spindly plants with pale leaves, whereas exposure to proper lighting can produce plants with shorter, stronger branches of dark green leaves. The rainbow effect created by holding a prism up to sunlight is a visual description of the colors in the light spectrum. Our perception of blue light, especially at shorter wavelengths (for example, 400 to 425 nm) is low compared to green […] Natural light varies daily and seasonally. Learn which plants thrive in your Hardiness Zone with our new interactive map! Plants use water and carbon dioxide to generate food and release oxygen into the atmosphere, a natural process that feeds all other life on our planet. Sunlight is the best light for plants. I have observed it in lawn grass and 2 different types of flowers. Light is the original source of energy for plant photosynthesis and growth. Some kinds of plants can survive with little or no light but the tomato plant is not one of them. She has contributed human interest and health articles to the "Lowell Sun," the "Portsmouth Herald," Valley Publishing, and Demand Studios. The seeds’ containers should be placed less than six inches from the light source. By the appropriate use of artificial light greater control over the growth and development of plants is possible. But the spectrum of light most utilized by a leaf is limited to three distinct colors, red, blue and yellow. The rapid development of lighting technologies using light-emitti… It also controls a plant’s cellular respiration and lessens water loss through evaporation during hot and dry conditions. Plants can use the energy contained in artificial light for photosynthesis. Optimal Plant Growth With Fluorescent Lights. It is a complex subject and in this paper the effects of different light conditions are discussed. white light.3 Plants have light receptors that detect visible light and generate a response. Overall, the best lighting choice should give off a high amount of blue, red and yellow light. Plants use light to create the energy needed to make the food they need to grow and a plant’s growth rate and longevity is dependent upon how much light it receives, according to the Texas A&M Agricultural Extension website. The green pigment chlorophyll, which is present in most plant life, absorbs light. It is an essential part of all life on Earth. Place plants within 10 feet of a sunny window. Effect of artificial light on plant growth. A simple incandescent light does not meet a plant’s requirements. Natural daylight from the blue part of the spectrum is optimum for the initial stage of plant growth. Indoor plants placed within 10 feet of a sunny window receive the natural balance of red and blue rays they need. Copyright Leaf Group Ltd. // Leaf Group Lifestyle. Effect of Artificial Light on Plant Growth Learn about the effect of artificial light on plant growth versus natural sunlight and delve into some biology and botany concepts in this science project. The blue and red lighted plants were close to grown. Climate, altitude, weather, fertilizer and pest control also affect plant growth and production. The same type of plants that grew in the same exact conditions except the color of light absorbed, reached different heights. Light is just one factor that influences plant growth. Red light can be used to induce flowering and lengthen the internodes to produce plants with longer stems and bigger flowers. Function. Artificial lights can be used to supplement natural sunlight or, in some cases, replace it completely. Light directly influences plant growth and flowering by inducing photosynthesis and feeding plants energy.
