The environment is called HydroNet and includes information and personalized support to hydroponics’ interested groups. The aim is to give the producer the opportunity to access for the first time hydroponics consulting services that meet his/her particular needs over the web. The environment consists of an underlying web services infrastructure. It supports training, support and recommendation services, adaptive web and user interaction services, remote online access services and GIS support services. The web services are coupled with smart mechanisms such as dynamic information flow, interface adaptation and intelligent web structure reorganization. The exploitation of various state of the art technologies takes place, in order to achieve a user centric approach for the collection, presentation and dissemination of data. Overall the environment aims at encouraging the development of hydroponics in Greece. Keywords Intelligent information environment, web services, hydroponics, hydronet. 1. INTRODUCTION Plant cultivation in greenhouses is internationally based ever increasingly on automated control systems. The existing infrastructure in contemporary greenhouses allows interconnection with information management environments. Consequently careful and intelligent integration using advanced information and communication mechanisms would assist the producer to record, classify, manipulate and receive advise about various data connected to various applied techniques such as yield data, disease control, plant physiology and market conditions. The result is improved yield
