This container is half the size of a British standard seed-tray. In fact two half-trays will fit into a standard tray with a little room to spare.
In practice many growers use half-trays without the support of any "outer". They have two levels of drainage for overhead or sub-irrigation. All edges are rolled down for comfort and safety when handling. Half-trays represent one of the most economical containers in which to grow many types and varieties of plants in smaller quantities.
