Abstract: A molded plastic sheet has many rectangular sprout growing trays joined together at top peripheral flanges. Each tray has drainage holes and a bottom sloping to the holes. A sheet of many trays may grow sprouts in preproportioned amounts. The flanges are divided by partially cut through lines for separation after growing. A transparent clamshell container receives the tray and holds it in place by the flange when closed The container has a front portion and a rear portion joined by a hinge, with rectangular perimeters which snap sealingly together. The lower part of the container holds the tray. It is sealed water tight. Above that part, one or more ventilation passages are provided in the container sides so that the sprouts may continue to grow while on retail display. A hanging tab is provided on the container top with an easy opening adjacent flap.
