Agricultural production is one of the main keys to the development of healthy societies. It is anticipated that agricultural systems will increasingly have to contend with temperature, humidity and water stress in the near future. This makes the need to increase the efficiency of land and water use ever more urgent. The control and design of greenhouses allows to increase dramatically the quality of crops and extend the cultivation period year-round. A properly designed autonomous greenhouse based on hydroponics can greatly reduce the amounts of nutrients and energy expended in agricultural production. This book deals with different types of greenhouses, materials, structures, advanced control techniques and tendencies that are needed for designing and controlling an advanced greenhouse. The control system is presented as an integral system which covers the explanation of basic and advanced concepts for a real time controller. Also, structural analysis is introduced, whereby mechanical design is regarded as a key factor. The book incorporates simulations and experimental results, and utilizes LabVIEW and ADAMS software. Finally, it provides a perspective on the present state and future of greenhouses globally. Written in a highly accessible manner, this book will prove useful to horticulturalists, agricultural engineers, greenhouse engineers and designers. Its easy-to-absorb contents are also suitable for (under)graduate students and researchers in agricultural and electronic engineering, horticulture, crop cultivation and soft computing.

Careful planning is important before a home greenhouse project is started. Building a greenhouse does not need to be expensive or time-consuming. The final choice of the type of greenhouse will depend on the growing space desired, home architecture, available sites, and costs. The greenhouse must, however, provide the proper environment for growing plants. The greenhouse should be located where it gets maximum sunlight. The first choice of location is the south or southeast side of a building or shade trees. Sunlight all day is best, but morning sunlight on the east side is sufficient for plants. Morning sunlight is most desirable because it allows the plant's food production process to begin early; thus growth is maximized. An east side location captures the most November to February sunlight. The next best sites are southwest and west of major structures, where plants receive sunlight later in the day. North of major structures is the least desirable location and is good only for plants that require little light. Good drainage is another requirement for the site. When necessary, build the greenhouse above the surrounding ground so rainwater and irrigation water will drain away. Other site considerations include the light requirements of the plants to be grown; locations of sources of heat, water, and electricity; and shelter from winter wind. Access to the greenhouse should be convenient for both people and utilities.

Crop production in greenhouses is a growing industry, especially in mild climates, and is very important for the population as a source of income and clean, fresh food. Greenhouses create optimal climate conditions for crop growth and protect crops from outside pests. At the same time greenhouse production increases water use efficiency and makes integrated production and protection (IPP) possible. This book provides technical instructions for practice (what to do and what not to do) and gives answers to the question: How to produce more clean crops and better quality with less water, less land and less pesticide. Suitable greenhouse constructions and their design, adapted to local climates in subtropical, tropical and arid regions and infrastructure conditions are presented. The necessary climate control measures - light transmittance, ventilation, cooling, heating, and CO2 enrichment - and physical measures for pest control, as well as methods for using solar energy to desalinate salty water are described. The results of theoretical research are transferred into methods for practical use, so that readers are equipped to solve their problems in practice as well as to get stimulation for further research and development.

With a revolutionary new “Climate Battery” design for near-net-zero heating and cooling By the turn of the nineteenth century, thousands of acres of glass houses surrounded large American cities, becoming a commonplace symbol of the market garden and nursery trades. But the possibilities of the indoor garden to transform our homes and our lives remain largely unrealized. In this groundbreaking book, Jerome Osentowski, one of North America’s most accomplished permaculture designers, presents a wholly new approach to a very old horticultural subject. In The Forest Garden Greenhouse, he shows how bringing the forest garden indoors is not only possible, but doable on unlikely terrain and in cold climates, using near-net-zero technology. Different from other books on greenhouse design and management, this book advocates for an indoor agriculture using permaculture design concepts—integration, multi-functions, perennials, and polycultures—that take season extension into new and important territory. Osentowski, director and founder of Central Rocky Mountain Permaculture Institute (CRMPI), farms at 7,200 feet on a steep, rocky hillside in Colorado, incorporating deep, holistic permaculture design with practical common sense. It is at this site, high on a mountaintop, where Osentowski (along with architect and design partner Michael Thompson) has been designing and building revolutionary greenhouses that utilize passive and active solar technology via what they call the “climate battery”—a subterranean air-circulation system that takes the hot, moist, ambient air from the greenhouse during the day, stores it in the soil, and discharges it at night—that can offer tropical and Mediterranean climates at similarly high altitudes and in cold climates (and everywhere else). Osentowski’s greenhouse designs, which can range from the backyard homesteader to commercial greenhouses, are completely ecological and use a simple design that traps hot and cold air and regulates it for best possible use. The book is part case study of the amazing greenhouses at CRMPI and part how-to primer for anyone interested in a more integrated model for growing food and medicine in a greenhouse. With detailed design drawings, photos, and profiles of successful greenhouse projects on all scales, this inspirational manual will considerably change the conversation about greenhouse design.

Greenhouse control system manufacturers produce equipment and software with hundreds of settings and, while they hold training courses on how to adjust these settings, there is as yet no integrated instruction on when or why. Despite rapid growth in the greenhouse industry, growers are still faced with a multitude of variables and no unifying framework from which to choose the best option. Consolidating 30 years of research in greenhouse climate control, Optimal Control of Greenhouse Cultivation utilizes mathmatical models to incorporate the wealth of scientific knowledge into a feasible optimal control methodology for greenhouse crop cultivation. Discussing several different paradigms on greenhouse climate control, it integrates the current research into physical modeling of the greenhouse climate in response to heating, ventilation, and other control variables with the biological modeling of variables such as plant evapo-transpiration and growth. Key topics include state-space greenhouse and crop modeling needed for the design of integrated optimal controllers that exploit rather than mitigate outside weather conditions, especially sunlight, given widely different time scales. The book reviews classical rule-based and multivariable feedback controllers in comparison with the optimal hierarchical control paradigm. It considers real and hypothetical examples including lettuce, tomato, and solar greenhouses and examines experimental results of greenhouse climate control using optimal control software. The book concludes with a discussion of open issues as well as future perspectives and challenges. Providing a tool to automatically determine the most economical controls and settings for their operation, this much-needed book relieves growers of unnecessary control tasks, and allows them to achieve the best possible trade-off between short term savings and optimal harvest yield.
