A patented new growing medium (NGM), made of biodegradable polyurethane agglomerated peat, was developed. On a weight basis, it consists of water (80%), peat (12-15%), and aggregating polymers (5-8%). The use of materials alternative to peat is under study. Among them, a promising one is bark fiber. Several plug shapes (also concerning seed niche) and sizes have been investigated over the time. A TFS-TP system was developed, consisting of plug units of the NGM, floating on a reusable polystyrene foam flat panel. Management in the greenhouse is similar to a standard TFS-TP system. Also more environmental-friendly alternatives to polystyrene foam panels are under study: made both of biodegradable foam polymers (BFP) or BFP-agglomerated paper/wood derivatives

Abstract
A patented new growing medium (NGM), made of biodegradable polyurethane agglomerated peat, was developed. On a weight basis, it consists of water (80%), peat (12-15%), and aggregating polymers (5-8%). The use of materials alternative to peat is under study. Among them, a promising one is bark fiber. Several plug shapes (also concerning seed niche) and sizes have been investigated over the time. A TFS-TP system was developed, consisting of plug units of the NGM, floating on a reusable polystyrene foam flat panel. Management in the greenhouse is similar to a standard TFS-TP system.
