To acquire best results from soil-less cultivation growers should adapt the irrigation strategy to the physical propertiews of the growing media and consider sustainability and environmental protection. Closed systems are more environmentally friendly than open systems. Growers are advised to keep records of all inpust and operations, regardless the production system. Besides helping the crop productio planning and inspections, this is an excellent basis to quantify the various parameters influencing the production price. Investment costs and a template table for calculation of variable costs are included in order to provide farmers with a tool to make an economic assessment.
