PURPOSE: A seedling-raising box comprising a main frame, an intermediate frame and a subframe and being length adjustable by the removal of the intermediate frame, if needed is provided. It permits a large amount of seedling to be raised at a time and prevents damage to roots during transplanting.

The receiving grooves contain one or more drain holes(103) to allow drainage.
