LEDs for the growing of green vegetables

Phytochromes, cryptochromes and phototropins play an important role in the mediation of plant growth. These photoreceptors are activated by specific light wavelengths and deficient amount of certain light wavelengths may lead to undesirable plant growth. Hence, the quality of light received by a pla...
