PROBLEM TO BE SOLVED: To provide plant raising light using LED intended for preventing indoor plant raising activity from being affected by weather or season and also for solving the problems that the vast ground has been needed because of conventional planar plant cultivation activities and plant raising period has been very long and much labor has been required as well. SOLUTION: The plant raising light using LED for photosynthesis enables indoor plant cultivation activities in contrast to the fact that conventional plant cultivation activities have mainly involved photosynthesis utilizing sunlight; thereby space can be utilized in a three-dimensional way, leading to performing agricultural activities even without the ground and without being affected by weather as well; besides, various kinds of plants can be cultivated in any season by merely regulating indoor temperature and humidity, and since these plants can be continuously irradiated with light even during the night, their growth is also effectively promoted.
