Abstract

Greenhouse production is a technologically-sophisticated industry where changes occur rapidly.
As a result, it is very challenging for growers to keep abreast of all new developments, while, at the same time, manage a demanding production schedule.
Growers are continually looking for assistance in their decision-making endeavours.
Some new tools to assist in decision making are the Internet and decision support systems.
