LEDs are set to change horticulture by increasing yields

Ninety percent of plant genes are regulated by light. So, by changing the light spectrum, it is possible to change how a plant grows, how fast it develops and its morphology. The color of LED light can be used not only to assist the growth of plants, but it can also be used to improve their year-round taste and quality and potentially increase their nutritional value. The advantages of LED are considerable: As well as altering the light spectrum, the low temperature of LED means that they can be placed near to the plants without damaging them. There are also no heavy metals or glass in LEDs, whereas sodium lights do sometimes break, leading to contamination.
