The usefulness of the light-emitting diodes (LEDs) in the growth of orchid plantlets is presented in this chapter. The construction of the Culture Pack-Rockwool (CP-RW) system and the LED Pack is described. When Phalaenopsis and Cymbidium plantlets were cultured using the CP-RW system under different blue to red LED ratios, the growth of plantlets was enhanced than those under plant growth fluorescent lamps (PGF). The positive effects of LED irradiation on plant growth indicate that LEDs will be a major light source for use in a wide range of micropropagation systems.
