Abstract
A molded plant tray is provided in the form of a unitary molded plastic member formed of relatively light foamed plastic and having downwardly extending tapered plant cells for receiving planting medium in which individual seedlings are grown. The plant tray is provided with integral drive member receiving groove means in the form of U-shaped grooves along bottom portions of intermediate walls that define the plant cells. An alignment groove can also be provided perpendicular to the drive member receiving groove means and bisecting the length of the drive member receiving groove means for accurate positioning of the plant tray relative to drive members. In a second embodiment a relatively hard plastic insert is molded, manufactured or adhesively secured to create a dual body tray in the molded plastic member and defines the plant cells.
