A hydroponic apparatus comprising: (a) troughs ( 12, 13, 14, 15, 16 ) linked together to form a continuous track located on guide wheel members ( 24, 26, 28, 30 ) in a support frame ( 32, 34 ), (b) a liquid supply means ( 36 ) to supply liquid to the troughs ( 12-16 ), wherein, in operation, the addition of liquid to one/some of the troughs ( 12-16 ) alters the weight distribution of the troughs ( 12-16 ) causing the track to move on the guide wheel members ( 24, 26, 28, 30 ) and thus allowing the troughs ( 12-16 ) which have become lighter as liquid is consumed by the plants and/or is lost through evaporation to move into position to be replenished with liquid. This movement is a continuous cycle according to changes in the weight distribution of the troughs ( 12-16 ) as liquid is being consumed and replenished. |
