Contents: 1. Introduction. 2. Greenhouse applications. 3. Hydroponic systems. 4. Hydroponic media and containers. 5. Hydroponic nutrition. 6. Care, maintenance and management. 7. Trouble shooting in hydroponics and management. 8. Appendix. Hydroponics is the method of growing plants using water and essential nutrients required without the presence of soil. Hydroponic farming can be useful in rough environments with the use of greenhouse or indoor farming with environmental control. By 2050, the earth's population is predicted to increase to 9.6 billion leading to decrease in land available for food production. Urbanization expanding cities need to develop alternate farming justify the implementation of hydroponic growing techniques as it does not require soil. All most all crops can be grown hydroponically. A knowledge of plant physiology and agronomic practice, would help to practice this fascinating industry to a common man and an industrialist. Round the year production of crops is possible. Through the initial investments are little bit higher, one can make huge profits with proper technical management and know how even by the beginners. This book provides the valuable information on the hydroponic technology. How to build simple system at home, and on a large scale in future. The chapters give ample information on the media used system in practice, Nutrient solution formulae, preparation, management, buildup of different system and how to proceed with day to day operations for successful hydroponic food production. The figures and illustration will make the reader to understand clearly the technology. The object of this book is to present consolidated information on hydroponics in a way to understand and attempt with curiosity for the contribution to the fare of society.
