LED Grow Light Features
As a fourth generation light source , LED has many characteristics different from other electric light , which makes energy-saving light source of choice. Applied to the field of plant cultivation LED also showed the following characteristics: rich wavelength type , just light and plant morphogenesis synthesis and optical spectral range consistent ; spectral -width half width , pure monochromatic light can be obtained in accordance with the needs of complex spectral combinations ; can concentrate specific wavelengths of light evenly illuminated crops ; not only can regulate flowering and seed crops , but also to control plant height and plant nutrients ; less heating systems , small footprint , can be used for a combination of multi- dimensional culture system , to achieve a low heat load miniaturization and production space ; addition, it is also particularly strong durability reduces operating costs. Because of these significant features , LED is suitable for a controlled environment plant cultivation facilities , such as plant tissue culture, horticulture and nursery and aerospace factory ecological life support systems.
LED Grow Light plant lights relative has many advantages over traditional , traditional artificial light sources generate too much heat, such as the use of LED supplemental lighting and hydroponic systems , air can be recycled, excessive heat and moisture can be removed , the power can be is efficiently converted to photosynthetically active radiation , the final conversion of plant material . Research shows that : the use of LED lighting, the growth rate of lettuce , photosynthetic rate have increased by more than 20 %. Mixed wavelength LED light source can significantly promote the growth of spinach, radishes and lettuce , improve morphological indicators ; able to make beet bioaccumulation largest hair roots beet pigment accumulation of the most significant and produce the highest sugar and starch accumulation in the hair roots .
LED Grow Light can affect plant growth cycle , a specific wavelength LED can affect flowering time of plants, the quality and duration of flowering . Certain wavelengths of LED can increase the number of flower buds and flowering plants ; certain wavelengths of LED can reduce flowering response , regulating the flowering stalk length and is conducive to the production of cut flowers and listing . Thus the regulation can be modulated by the LED and the subsequent growth of flowering plants.
