I have been operating a dye company for a long time and focused on a plant factory as part of a new business. Since introducing a small-scale cultivation device a year ago, the result of the Japanese advanced agri hydroponic cultivation system and trial cultivation of 3 wavelength light source was good, we have reconstructed one corner of our company, the plant factory expanded this time. The company's cultivation system was arranged in a freely configurable manner and it was expandable so that it was able to make the best use of the limited compartment expanded.
