A grow light or plant light is simply a man made source of light for plants. Grow lights are generally referred to as lights that stimulates the growth of plants by emitting electromagnetic spectrum which is useful for plant to photosynthesize.
Grow light is of importance in situations of absence of natural sunlight or when the hours of available Sunlight is not suitable for plant growth. Grow lights are then used to extend the time to meet the plant requirement.
Grow lights performs two major functions: It is either used to provide light spectrum close to the spectrum produced by sunlight, or to provide light spectrum that is best for the plant need. Grow light uses different colors, temperature, intensity and other conditions are mimicked. In summary using grow light is close to the natural environment.
In 1868, Russian botanist ANDREL FAMINSTYN was the first to use artificial light for plants growing and research.
USES OF GROW LIGHTS
Grow lights are basically used for the following
Indoor hydroponics and
Which simply means the cultivation of flowers, this can be very effective and will give a suitable output when the factors (natural light) responsible for growth of those flowers are insufficient, the growth light will be introduced. Since grow lights helps provide the required material need ed instead of sunlight by providing the appropriate light spectrum for photosynthesis. If grow lights are introduced to flowers there won’t be any unrest of light problems since the flowers receive the spectrum emitted which provide the essential material needed like sunlight do.
During indoor gardening the flowers or plants do not have access to much light and thus may not give a greater output or even experience stunted growth. Since they need light to carry out every production, the introduction of grow light can help in this case. The grow light thus helps in ensuring rapid growth of indoor plants.
This process involves creating new plants from a variety of source such as seeds, cutting , bulbs, and other plant part. Propagation at times might be referred to as artificial or natural dispersal of plants. When such plants are propagated they really need the presence of light to stimulate germination and enable continual growth process. When grow light is introduced to such propagated plants, it gives such plants much strength to grow since it provides essential material by emitting electromagnetic spectrum that functions as well as photosynthesis which makes propagated plants grow well within short timer interval.
Most food has its source from plants, some are obtained directly from plants while some needs to be processed.In recent days they have been a growing trend towards sustainable agriculture, ideas have been brought and some activities have been practiced to facilitate production of more food. Sometimes when natural light seems to cause setbacks in food production . Since we consume food everyday and failure to put effort in food production may lead to famine or hunger. Recent research now provides another means to provide light in the absence of sufficient sunlight which is the Fluorescent grow light. Since the inception of the use of fluorescent grow lights in combination with use of fertilizers and manures foods tend to grow more faster and produce more yields.
Indoor hydroponics means the act of growing plants without soil. It involves using mineral nutrient solution in a water solvent. This is done in an enclosed place which have access to little or no light which may lead to stunted growth.
So how can this be corrected; its through the use of fluorescent grow lights which supplements the photosynthetic activities of sunlight.
In aquatic planting grow light may also be introduced as light sources to enable photosynthesis for aquatic plants that require sunlight.
Aquatic plants which require special adaptation for living submerged in water or at water surface .Aquatic plant can grow in water or in soil that is permanently saturated with water, but after all this process require sunlight.
The light enables photosynthetic and chemical process that stimulates plant growth. That’s where the growth light will will provide the material required for the plant through light and thus making it grow efficiently and effectively.
Different types of grow lights ranges from the fluorescent grow lights to the LED grow lights etc.
