Effects of light emitting diode lights on plant growth, development and traits a meta-analysis

The various monochromatic Light Emitting Diode (LED) lights are widely used in growth facility for cultivating various plants, particularly horticultural crops because of their higher luminous efficiency, lower radiation and power consumption than the traditional white fluorescent lamp light. Howeve...
