ABSTRACT:
A molded plastic seedling tray with an array of depressions thereon, with holes in the bottom of the depressions, each depression comprising a germination cell for growing plants. A perimeter side wall around the edge of the tray holds the germination cells up from the supporting surface so as to insure an air circulation chamber under the cells. Indexing holes are formed in the perimeter at intervals equal to the space between cells so that a planting machine can engage the holes and index the cells by one hole at a time, and thus one cell at a time. The indexing holes also provide root drying ventilation to enable self pruning.
