<P>PROBLEM TO BE SOLVED: To provide a hydroponic panel intended for solving such problems wherein with a conventional type of hydroponic panels having holes different in size and interval are required according to a plant to be cultivated, so variations are required for hydroponic panels and a large space becomes necessary for storing panels, thereby increasing cost. <P>SOLUTION: This hydroponic panel is such that many planting small holes and planting big holes with an internal diameter bigger than that of the small hole are piercedly opened on a panel to be covered on an upper opening part of a hydroponic bed, while the small holes are piercedly opened in a few lines, and the big holes are piercedly opened on desired places between the small holes. The internal diameter of the big hole is large enough to pierce a water absorbing material bigger than the internal diameter of the small hole and drop down on the bottom of the bed, and the big hole has one kind size or at least two different kinds of sizes. The small holes are opened in a few lines on a place positioned above cultivation liquid paths of at least two lines divided on the bottom of the bed when covering the panel on the bed. The big holes are opened between the small holes and on a place positioned above the cultivation liquid paths. <P>COPYRIGHT: (C)2009,JPO&INPIT |
