Five-day Introductory Training Course on

Plant Factory with Artificial Lighting (PFAL)

October 1st – 5th, 2018


 In response to increasing global demands from indoor farmers, researchers and future entrepreneurs in the exciting emerging field of plant factory with artificial lighting (PFAL), also known as vertical farm, this coming October, Japan Plant Factory Association (JPFA) together with Chiba University will host an intensive five-day introductory training course in English on PFAL.
Since 2010, JPFA and Chiba University have been organizing various in-depth and practical sessions, including introductory to advanced courses. This five-day introductory session in English, held October 1st -5th, covers what you would need to know before or after starting PFAL business or research. The sessions will be interactive academic and practical classes, covering topics such as structure and function of PFAL, environmental control, lighting, plant physiology, nutrient solutions, seedlings, recent new technology, and business case studies of commercial large-scale PFALs. In addition to lectures by academic professionals and PFAL representatives, optional excursions to some commercial PFALs on the last day of the course will be organized.

1. Objective and Goal

  -To offer foundation for theory and experience-based practice, with a view to foster academic and industrial development toward next generation PFAL.

 -To facilitate development and dissemination of technically and economically sustainable PFAL, through providing the firsthand technical and conceptual classes by broad-ranging professionals in practice from both academia and PFAL industry.

2. Target group: Who would attend?

Motivated current/potential indoor farmers who plan to start or just started PFAL business or research. They will gain understandings of elementary theory and practice of PFAL, basic knowledge of cultivation and operational management, and keys for business success, etc.

3. Lecturers and program
