Why do plants posses accessory pigments? Yet the red and blue parts of the light spectrum are the most important energy sources for plants, and plants require more rays from the red range than from the blue. Plants growing outdoors, in greenhouses or close to windows are exposed to a natural balance of the blue and red light rays that plants need.

Green light: Is it important for plant growth? Plants grown with 50 percent green and 50 percent red light were approximately 25 percent shorter than those grown under only red light, but approximately 50 percent taller than all plants grown under more than 25 percent blue light (Photo 2).reen light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture.

Plants and Shade Most plants grow best in full sunlight and all plants need some light to survive. The amount of shade a plant is growing under will directly affect the density of the foliage, as well as the flowering and fruiting characteristics.sually fewer flowers develop on plants in the shade. Frequently, fall color or unique foliage colors (e.g., maroon foliage of ‘wine and roses’ Weigela and red leafed Japanese maples) will not be as intense or maybe greener in color under shade conditions.

Frequently Asked Questions Advances in fluorescent lighting technology, however, have provided more options for horticulturists. T5 fluorescent lighting is the latest in plant growth lighting. T5’s high-light output combined with its low heat and energy consumption makes it an ideal light source to grow a broader array of plants.ID lighting stands for High Intensity Discharge, which is a special type of lighting that is much more intense (brighter) than other types of lighting available. An HID lighting system consists of a ballast, reflector, socket and lamp (light bulb).

What Kinds of Light Do Plants Grow Better In? Light consists of several colors, but plants do not need all of the colors. Red and blue are the most important colors required by plants for energy. Of the two, red light is more important. Plants that receive natural light through windows or by growing outdoors receive the proper balance of red and blue light.

Starting from Seed For optimal growth, seedlings need 12 to 16 hours of light a day, so if you’re low on south-facing window-sills, you’ll probably need to use some kind of supplemental lighting. Fluorescent lights work well but need to be within six inches of the seedlings or you’ll end up with tall, spindly plants.

What Makes Plants Grow: Plants Growing Needs Light & Temperature. Plants also need sunlight to grow. Light is used as energy for making food, a process called photosynthesis. Too little light can make plants weak and leggy looking.They will also have fewer flowers and fruits. Temperature is important too.n addition to essential nutrients found in soil (from organic matter and micro-organisms), soil provides an anchor for plant roots and helps support the plants. Light & Temperature Plants also need sunlight to grow.

- Answer 1: As you know, plants get their energy from light, but you might not know that different colors of light have different energy levels. Think about the colors of a rainbow. All of these colors are in white light. If you use a prism, you can separate the white light into the colors.

Indoor Plant Lights Give a plant too much sun and it will look bleached, pale, or event burned; too few hours and it will have thin leaves and elongated shoots. Some plants require about a half day of light, while others need up to 18 hours of light each day; the latter include vegetables, which will get pale without sufficient light. Still others, such as African violets, need only about eight hours of light per day year-round. Many indoor plants might get a few hours of direct sun each day, but the angle at which the sun hits a window can be undependable. And natural light isn't strong or long enough to grow herbs or vegetables indoors.

Why do some plants appear green? The two kinds of chlorophyll in plants complement each other in absorbing sunlight. Plants are able to satisfy their energy requirements by absorbing light from the blue and red parts of the spectrum. However, there is still a large spectral region between 500 and 600 nm where chlorophyll absorbs very little light, and plants appear green because this light is reflected.

How to Choose a Grow Light In most cases, even the sunniest windowsill will not provide the intensity of light they need. The best solution is to grow your seedlings under fluorescent lights. Growing plants under lights, lets you control light intensity in two ways: the wattage of the bulb and how close the bulb is to the plant's foliage.Fluorescent bulbs are ideal for seedstarting because they give off very little heat.hen starting seeds indoors, one of the most important factors is light. Sure, you’ll want to choose a good seedstarting mix and establish a good watering routine, but proper lighting is crucial for healthy, stocky seedlings.

Light Some kinds, such as Phalaenopsis and Paphiopedilum, can do well under artificial lights. Flourescent lights work well, and are energy efficient. Keep the lights 6-8 in/15-20 cm above the plants, but check that the bulbs do not burn leaves. Some orchids require bright light, but no direct sun. Orchids such as Phalaenopsis and Paphiopedilum live as epiphytes in lower parts of the forest. Trees and clouds block the direct rays of the sun.

- Light is so important for plant growth that they actually bend over backwards to get their share! Think about it this way. The plant cells that are on the shady side of the plant actually grow longer than the cells on the sunny side. These longer cells grow this way because of a chemical in them called an auxin. An auxin, is a plant growth hormone that helps regulate shoot growth. Under normal light conditions auxins are spread out in the plant. But when sunlight varies, auxin is broken down on the sunnier side of the stem. The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bends toward the light. Because light is the energy source for plant growth, plants have evolved highly sensitive mechanisms for perceiving light.
