Technical Examples
  1. 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.
