29. Challenges
Revolutionary Low Cost is required
• A conceptual breakthrough is requested Fresh, Processed (paste etc.)
• Information exchange and discussion among different industries are most
important.
• A hardware only solution is inefficient (The combination of breeding
(cultivar) and cultivation techniques is important.)
• Long term prospect: Overseas development
• Short term prospect: Large-Scale facilities (Plant factory special zones)
• Introduction of IT, downsizing and reducing cost of control systems
• Reduce labor cost and product cost ( automation, development of labor
saving devices)

34.  Supplying a limited amount of
Nitrogen per plant to control LAI
 The nutrient solution can be
uniformly supplied to all the plants.
 Supplying sufficient oxygen for a
root can be continued.
