ABSTRACT:
The system includes an efficient, closed irrigation system in conjunction with insulating components for minimizing the harmful effects of extreme changes in ambient temperature, moisture and chemical concentrations in plant containers. Mechanisms are provided for permitting a single pallet, or a single plant within a pallet, to be readily removed from an integrated plurality of pallets without interfering with irrigation of the plants that are contained in the remaining pallets.
