I took a half day off on Friday to refresh myself. The place I went was "PASONA O2" which was a greenhouse inside a building. It is a three-minute walk from Otemach station and you could look around at various plants for free.
They grow flowers, herbs, vegetables and rice in the basement with cutting-edge agricultural technology, like the artificial light used instead of sunlight. For example, the flowers are living under a light of white LED, because it is kind of light to make them look beautiful. In terms of herbs, red light from a high presure natrium lamp accelerates the time it takes for them to bloom, and blue light from a metal halide lamp is also really important for them to gather nutrients.
What really interested me most was a meeting space surrounded by these kinds of unique plants. If a business meeting was held there, any project would go in a positive way thanks to the atmosphere full of negative ions.
Although I just went to this place for rejuvenation, the facility was build for residents of urban areas to develop an interest in agriculture. It also gives us an opportunity to be a agricultural intern. I never imagined plants could be grown in such a futuristic and artificial place untill I visited here...
