This professional horticulture reference, which has been in print continuously for 70 years, is fully revised and updated in this new edition. Based on real-life experiences from industry professionals including growers and equipment and greenhouse manufacturers, the presented information covers all aspects of greenhouse equipment—the structures themselves, benches, irrigation, curtains, environmental controls, machination, and the greenhouse as a retail facility. Discussed are the most recent developments in greenhouse evolution and the varieties of greenhouse structures available, from freestanding and gutter-connected to shade houses and open-roof greenhouses. There are many types of glazing available for each greenhouse, and the differences between glass, polyethylene film, and rigid plastic are explored. Also included is information on managing the greenhouse, marketing products, and operating a retail store from a greenhouse. This replaces 1883052157.
