Plant Factory Basics, Applications, and Advances takes the reader from an overview of the need for and potential of plant factories with artificial lighting (PFALs) in enhancing food production and security to the latest advances and benefits of this agriculture environment. Edited by leading experts Toyoki Kozai, Genhua Niu, and Joseph Masabni, this book aims to provide a platform of PFAL technology and science, including ideas on its extensive business and social applications towards the next-generation PFALs. The book is presented in four parts: Introduction, Basics, Applications, and Advanced Research. Part 1 covers why PFALs are necessary for urban areas, how they can contribute to the United Nations' Sustainable Development Goals, and a definition of PFAL in relation to the term "indoor vertical farm." Part 2 presents SI units and radiometric, photometric, and photonmetric quantities, types, components, and performance of LED luminaires, hydroponics and aquaponics, and plant responses to the growing environment in PFALs. Part 3 describes the indexes and definition of various productivity aspects of PFAL, provides comparisons of the productivity of the past and the present operation of any given PFALs, and compares PFALs with one another from the productivity standpoint by applying the common indexes. Part 4 describes the advances in lighting and their effects on plant growth, breeding of indoor and outdoor crops, production of fruiting vegetables and head vegetables, and concluding with a focus on a human-centered perspective of urban agriculture. Providing real-world insights and experience, Plant Factory Basics, Applications, and Advances is the ideal resource for those seeking to take the next step in understanding and applying PFAL concepts.

This book provides two basic concepts on plant propagation and value-added transplant production in a closed structure with artificial lighting: 1) photoautotrophic (sugar-free medium, photosynthetic or inorganic nutrition) micropropagation systems, and 2) closed transplant production systems with minimum resource consumption and environmental pollution. This book also describes the methodology, technology and practical techniques employed in both systems, which have been commercialized recently in some Asian countries such as China and Japan. We often use a closed structure such as a tissue culture vessel, a culture room, a growth chamber, a plant factory with lamps, and a greenhouse to propagate plants and produce transplants. Main reasons why we use such a closed structure is: 1) higher controllability of the environment for desired plant growth, 2) easier protection of plants from damage by harsh physical environment, pathogens, insects, animals, etc, 3) easier reduction in resource consumption for environmental control and protection, and 4) higher quality and productivity of plants at a lower cost, compared with the plant propagation and transplant production under rain, wind and sunlight shelters and in the open fields. Thus, there should be some knowledge, discipline, methodology, technology and problems to be solved on plant propagation and transplant production common to those closed structures, regardless of the types and sizes of the closed structure.

Plant Factory: An Indoor Vertical Farming System for Efficient Quality Food Production, Second Edition presents a comprehensive look at the implementation of plant factory (PF) practices to yield food crops for both improved food security and environmental sustainability. Edited and authored by leading experts in PF and controlled environment agriculture (CEA), the book is divided into five sections, including an Overview and the Concept of Closed Plant Production Systems (CPPS), the Basics of Physics and Physiology - Environments and Their Effects, System Design, Construction, Cultivation and Management and Plant Factories in Operation. In addition to new coverage on the rapid advancement of LED technology and its application in indoor vertical farming, other revisions to the new edition include updated information on the status of business R&D and selected commercial PFALs (plant factory with artificial lighting). Additional updates include those focused on micro and mini-PFALs for improving the quality of life in urban areas, the physics and physiology of light, the impact of PFAL on the medicinal components of plants, and the system design, construction, cultivation and management issues related to transplant production within closed systems, photoautotrophic micro-propagation and education, training and intensive business forums on PFs.

Climate change is recognised as agriculture’s biggest challenge to date.* With increasing temperatures and an escalation in the frequency and severity of extreme weather events, agricultural productivity remains at risk of being compromised. With the food security of millions threatened, there remains a need to develop alternative, sustainable production models which can thrive in the face of climate change. Advances in plant factories: New technologies in indoor vertical farming reviews the wealth of research on optimising plant factories with artificial lighting (PFALs) as one potential solution to achieving a more sustainable agriculture. The book addresses developments in process monitoring, optimizing energy use, as well as adjusting lighting conditions to improve the sensory and nutritional quality of a range of horticultural crops. It also includes case studies of successful plant factory operations. Through its exploration of the development and application of PFALs in agriculture, the book highlights the growing importance of controlled environment agriculture technologies as a solution to maintaining global crop production in a time where our climate remains as unpredictable as ever.

This book describes the concept, characteristics, methodology, design, management, business, recent advances and future technologies of plant factories with artificial lighting (PFAL) and indoor vertical farms. The third wave of PFAL business started in around 2010 in Japan and Taiwan, and in USA and Europe it began in about 2013 after the rapid advances in LED technology. The book discusses the basic and advanced developments in recent PFALs and future smart PFALs that emerged in 2016. There is an emerging interest around the globe in smart PFAL R&D and business, which are expected to play an important role in urban agriculture in the coming decades. It is also expected that they will contribute to solving the trilemma of food, environment and natural resources with increasing urban populations and decreasing agricultural populations and arable land area. Current obstacles to successful PFAL R&D and business are: 1) no well-accepted concepts and methodology for PFAL design and management, 2) lack of understanding of the environmental effects on plant growth and development and hydroponics among engineers; 3) lack of understanding of the technical and engineering aspects of PFAL among horticulturists; 4) lack of knowledge of the technical challenges and opportunities in future PFAL businesses among business professionals, policy makers, and investors and 5) lack of a suitable textbook on the recent advances in PFAL technologies and business for graduate students and young researchers. This book covers all the aspects of successful smart PFAL R & D and business.

The second chapter explores the benefits of plant factories with artificial lighting (PFALs). The chapter assesses resource consumption, costs and performance of current PFALs, as well as methods for reducing resource consumption and production costs. The third chapter explores recent advances in the ornamentals industry, such as vertical propagation systems and LED technology, and how these can be implemented to meet the challenges of a changing marketplace and societal demands. The fourth chapter describes the advantages and disadvantages of hydroponics, along with the equipment and substrates used, and also examines soilless/hydroponic growing systems for vegetables. The final chapter describes the most recent innovation in hydroponic technologies for plant cultivation within cities and their adaptability to the urban fabric.

This book focuses on light-emitting diode (LED) lighting, mainly for the commercial production of horticultural crops in plant factories and greenhouses with controlled environments, giving special attention to: 1) plant growth and development as affected by the light environment; and 2) business and technological opportunities and challenges with regard to LEDs. The book contains more than 30 chapters grouped into seven parts: 1) overview of controlled-environment agriculture and its significance; 2) the effects of ambient light on plant growth and development; 3) optical and physiological characteristics of plant leaves and canopies; 4) greenhouse crop production with supplemental LED lighting; 5) effects of light quality on plant physiology and morphology; 6) current status of commercial plant factories under LED lighting; and 7) basics of LEDs and LED lighting for plant cultivation. LED lighting for urban agriculture in the forthcoming decades will not be just an advanced form of current urban agriculture. It will be largely based on two fields: One is a new paradigm and rapidly advancing concepts, global technologies for LEDs, information and communication technology, renewable energy, and related expertise and their methodologies; the other is basic science and technology that should not change for the next several decades. Consideration should be given now to future urban agriculture based on those two fields. The tremendous potentials of LED lighting for urban agriculture are stimulating many people in various fields including researchers, businesspeople, policy makers, educators, students, community developers, architects, designers, and entrepreneurs. Readers of this book will understand the principle, concept, design, operation, social roles, pros and cons, costs and benefits of LED lighting for urban agriculture, and its possibilities and challenges for solving local as well as global agricultural, environmental, and social issues.
