An apparatus for use in growing a plant crop, the apparatus comprising a structure enclosing a volume in which a crop can be maintained in a controlled environment during the growth of a crop, the structure housing two endless belts in spaced-apart parallel relationship and mounted for synchronous motion about a closed path, a trough to removably retain a nutrient solution for a crop, suspension means to enable a container holding a crop to be suspended between and move with the belts, the paths of the belts being such as to at least partially immerse the container in nutrient solution and feed a crop at least once on a complete belt circuit.
