An apparatus for transferring an upright tray at high speeds that can sense an entrance and discharge of the tray. The plant has shown resistance to botrytis, snails, and caterpillars. Each of the recesses is configured to receive and align one of the modular printer assemblies with the other modular printer assemblies. The invention initially allocates a minimum sized command window. Preferably, the polysilicon layer is doped with an impurity to provide conductive characteristics. 3 mm in width, and are inserted into the sealed capsule through the sealing wall before the hot water is fed into the sealed capsule, and so that the relative longitudinal slits extend inside the sealed capsule by respective lengths at least equal to a third of the depth of the relative cup-shaped body.
