Both natural and artificial light energy can be converted into chemical energy and nutrient stored in plant through the photosynthesis process.  However, only ~10% of natural lighting and ~30% of artificial lighting was used by plant to drive the chemistry. How to maximize the usage of lighting without further damages to the fragile environment becomes an important issue to be addressed by urban farming. Natural lighting for the greenhouse and outdoor farming, especially in tropical country like Singapore, more than 70% of the sunlight is diffused or too strong for effective plant growth. Various problems of using natural lighting for urban farming will be discussed in the talk.

In contrast, artificial lighting particularly, LED grow lights, are widely used by indoor farming exhibits a common problem, that is, huge energy consumption and limited power supply available within the country.  In this talk, areas that cause high energy consumption of using artificial lighting in indoor urban farming will be discussed.Finally, several potential solutions to improve the sustainability of using both natural and artificial lighting for urban farming will be shared.
