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.

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.

Modern greenhouse technology has revolutionized the food supply chain scenario over the past 40 years. Closed-field cultivation by means of agri-cubes, plant factories, vertical farming structures, and roof-top solar greenhouses has become the backbone of sustainable agriculture for producing all-year-round fresh fruits and vegetables. This book is an attempt to explore several profound questions such as how digital technology and simulation models have saved energy in commercial greenhouses, and why growers prefer LPWAN sensors and IoT monitoring devices over the traditional timer-based controllers? How artificial intelligence is capable of performing microclimate prediction and control, and what considerations should be taken into account for implementing desiccant evaporative cooling systems? With case-study examples and field experiments, each chapter highlights some of the most recent solutions and adaptation strategies toward improving the efficiency and sustainability of closed-field crop production systems.

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.

A growing number of people at least have one greenhouse story to share. The idea of growing food at controlled temperatures all year round and extending the growing season have set fire to people’s imaginations. No wonder the greenhouse building industry has recorded phenomenal growth. From construction plans to tools and accessories for greenhouses, individuals are working on all fours to satisfy the increasing demands of consumers who have made building their own greenhouses top priority. This trend, which started humbly in the 70’s, is now a full-fledged endeavor on the part of greenhouse entrepreneurs and “homesteaders.” One greenhouse story told by a woman was particularly moving. Months before the spring, her husband bought the materials required for building a greenhouse. His plan was to attach it to the house. The woman had protested because he was at the same time going through radiation and chemotherapy treatments for his cancer. His wife said he should be resting instead of puttering about with shelves and glass and plastic. What he said broke her heart. He wanted to build and finish the greenhouse while he still had some strength left, because he knew for a long time that she had always wanted one in their backyard. He said he wanted to see the joy in her face when she started planting her tomatoes or gardenias or whatever else she wanted to put there. Greenhouses are an extension of our personalities. Most especially, it mirrors our soul and what we want from life.

He said he wanted to see the joy in her face when she started planting her tomatoes or gardenias or whatever else she wanted to put there. Greenhouses are an extension of our personalities. Most especially, it mirrors our soul and what we want from life. And what we want is a steady supply of home-grown healthy food. During these precarious times when terrorist attacks and life-threatening calamities can cast us in the dark indefinitely, we have one thing we can be sure of – the tomatoes and cucumbers that are in the food basket in the kitchen will tide us over should the country go on emergency mode. The sweet potatoes and carrots will be around, and there will be more from the greenhouse to feed our families for a few weeks before things return to normal. Not that we believe that a shortage will ever happen, the country has become much more prepared for any kind of emergency, but just on the off chance... If greenhouses can save our lives, we may, at some point in time, consider the idea of building one soon, a first step towards self-sufficiency. It’s not just a constant supply of healthy food that concerns individuals, but a greenhouse – and building it – can be sources of pure enjoyment and clean fun for everyone in the family. Most greenhouse owners are familiar with the advantages of growing their own plants and flowers, prolonging the growing season and the possibility of heating their home. And who knows? They could be selling fresh produce in the communities they live in. There are many greenhouse models to choose from. You can go from affordable to very expensive. You can build a greenhouse by using junk or a plastic film stretched over a rudimentary structure, or purchase elaborate metal and glass pre-manufactured sun-rooms. Each of them serves the fundamental function of extending the growing season. Even the question of irrigation can be simple or complex, depending on your preferences. Just want to make it a hobby? Why not? Homeowners attach theirs to their homes. Even schools have greenhouses built by elementary and high school students. Finally, the wholesome taste of a home-grown tomato! Everyone knows there is a difference. But really, between you and I, it goes beyond just tomatoes. Perseverance, labor of love and the sweet anticipation of “harvest time” are what truly matter.
