Abstract: The invention relates to a device comprising a trough (2) with a base wall (4) and side walls (5), said trough (2) designed to contain a liquid and a tray (3) for placing in the trough (2), for supporting a growing substrate with at least one well (15), the bottom of which communicates with the liquid in the trough (2) each of which has an adjacent breaking zone (7, 12), the cutting of which permits the device to be divided up.

Abstract: A device having a tray defining at least one reservoir designed to contain a liquid, a platform, designed to be placed on the tray and to support a growing substrate, the platform including a flat main portion provided with wells having, at the bottom, an orifice communicating with the liquid contained in the tray, and means for carrying liquid in the reservoir, where a plurality of reinforcing walls protrude perpendicularly upwards from the main portion of the platform, where these walls have sufficient height so that, when the platform is placed on the tray, their top edge forms the highest portion of the device, and where the reinforcing walls are distributed on the surface of the platform so as to allow a distribution of the loads applied to this device.
