Raised bed structure improvements

A modular above-ground vertical farming structure for use in an outdoor environment, comprising:

• a rigid top bed;
• at least one rigid shaded bed;
• and
• a framework adapted for mechanical coupling to the top bed and the at least one shaded bed such that, when coupled, the framework supports the top bed and the at least one shaded bed and maintains the top bed and the at least one shaded bed in vertically stacked alignment, the framework comprising a plurality of supports;
• wherein the top bed and the at least one shaded bed each comprise a horizontal platform with a top surface surrounded by at least one wall and configured to support a load of a heavy plant growth medium received in each of the top bed and the at least one shaded bed;
• a reservoir coupled to the structure and configured to prevent water percolating from the rigid top bed to the at least one rigid shaded bed.
