More Efficient Plant Growth with Quantum Dots by Nanoco Lighting
Using LEDs for plant growth lights is nothing new, nor is the use of QDs in LED lighting. While it is already proven that LED systems have big advantages over conventional plant lighting technologies, it is not common knowledge that Cd-free QDs are ideal candidates for optimizing the light spectrum for plant growth systems. Dale Needham, Business Development Director-Lighting at Nanoco Lighting, explains the opportunities and advantages based on Nanoco’s proprietary and patentprotected CFQD cadmium-free quantum dot LED grow lighting systems.
For plants to thrive, they require the full-spectrum light of the sun; chlorophyll in the foliage absorbs sunlight to provide energy for all of the plant’s needs, while photosynthesis - using wavelengths between 400 and 700 nanometers (nm) - is the plant’s process of converting light energy from the sun. Most plants do not need all of the color bands in the visible spectrum. For instance, flowering plants use the full spectrum of visible light, but some wavelengths are more important than others. Red light is crucial for hormone activation, which powers the flowering and fruiting processes, while blue light encourages the compact “bushy” appearance of healthy plant growth. For this reason, growers relying on artificial plant lighting such as LEDs concentrate on the blue and red parts of the spectrum.
Precise spectrum light, along with the intensity and duration of that light, simultaneously triggers plant flowering, growth, and reproduction, yet plants are quite selective in the light they use. Generally, their requirements are limited to small, specific bands of light, and they reject any additional light that’s not needed. This might suggest that sunlight is rather inefficient as a plant’s energy source, but, due to its abundance of light energy, wastage is hardly noticed. In grow lighting environments, however, the exact amount of lighting that’s needed for plant growth must be provided artificially, while too much lighting can be harmful to plants, inefficient, and quite costly for vertical system farmers.
