Description

A greenhouse provides an essential means of livelihood to its owner and must be economically practical for the particular climate in which it stands. Greenhouses: Advanced Technology for Protected Horticulture addresses the major environmental factors of light, temperature, water, nutrition, and carbon dioxide, and features extensive discussions of greenhouse types, construction, and climate control. The book highlights technology such as hydroponics, computer control of environments, and advanced mathematical procedures for environmental optimization. Greenhouses: Advanced Technology for Protected Horticulture is the definitive text/reference for the science of greenhouse engineering and management.

The author Dr. Joe J. Hanan, Professor Emeritus of Colorado State University, is the recipient of the Society of American Florists' (SAF) 2000 (Millenium) Alex Laurie Award for Research and Education. The Alex Laurie Award is presented annually to an individual who has made broad-scope, long-lasting contributions to the floriculture industry through research or education. The award is named for Alex Laurie, a professor at The Ohio State University, who pioneered work in many areas of floriculture.

"Joe is one of the most precise floricultural researchers I have known," said Dr. Gus De Hertogh, Chairman of SAF's Research Committee. "That excellence is reflected in his latest book, Greenhouses, Advanced Technology for Protected Horticulture, which was published in 1998, nine years after his official 'retirement.'"
