An automatic and modular system for handling trays (32) used for containing plants or the like to be grown through hydroponic, or aeroponic, or aquaponic farming, comprises a first module (30) with a quadrangular plan and a vertical arrangement delimited by respective vertical supports (31), said first module (30) comprising two lateral zones, each of which includes a plurality of substantially horizontal and overlapping supporting seats or guides (37, 37') for trays (32), and a central zone in which a vertical tray transfer device (33) operates, slidably along a vertical axis (Z) arranged on a movement means activated by motorisation assemblies (34) able to translate said vertical transfer device (33) from a lowered position to a raised position for bringing itself to each tray (32) and vice versa, said vertical transfer device (33) being provided with a resting shelf (33') for a tray (32) and with a first means adapted to translate along a first horizontal axis (Y) said tray from and towards a respective seat provided inside one of said lateral zones. Said first module (30) further comprises a second means (36) arranged in said central zone in which said elevator device (33) operates, adapted to take in charge a tray (32) when the latter is located on the shelf (33') of said elevator device (33) and to displace said tray (32) along a second axis (X) horizontal and orthogonal to said first horizontal axis (Y) for performing the direct transfer of said tray (32) towards a further shelf (33') of a further vertical transfer device (33) of a second module (30) arranged adjacent and connected to said first module.La présente invention concerne un système automatique et modulaire pour manipuler des plateaux (32) utilisés pour contenir des plantes ou similaires destinées à être cultivées par l'intermédiaire de culture hydroponique, ou aéroponique ou aquaponique.
