Speech title "Use of LEDs for Better Control of Plant Growth and Development in Controlled Environment Agriculture"

Abstract-Controlled environment agriculture (CEA) such as plant factories are getting more and more attention worldwide as a production platform for many plants such as horticultural, medicinal and pharmaceutical plants. With the development of related technology, we now even see the commercialization of hydroponic plant cultivator as a modern home appliance. With the development of such artificial lighting systems as the light emitting diodes (LEDs), diverse plants can now be grown by using the artificial light as the sole source of light in place of the sunlight and even high output-type lamps which accompany a significant amount in thermal wavelengths troubling the control of CEA environment, especially temperature, in the warm seasons or areas. Light energy emitted from the LED lighting systems is less in the thermal spectrum, but falls mostly in proper spectra for plant growth and development. In addition, it is controllable in terms of intensity, quality, duration and direction for enhanced photosynthesis, morphogenesis and photoperiodic responses, enabling growers for better control of the growing environment for enhanced growth and development of their plants grown in. In this talk, my experience on using controlled environment, including home hydroponic cultivators, adopting LEDs as the sole light source for controlled growth and development, morphogenesis, and photoperiodic flowering in vegetables, flowers and medicinal plant species will be discussed.
