My "Gorilla Shelf" units from Sam's are only 18 inches deep, but I use pretty sturdy trays (recently switched to the light green perma-nest trays that hold up longer, got mine pretty reasonably in quantity from Park Seeds), and I just let the trays hang off the front and back edge a couple of inches. Setting the shelf up in a double side-by-side configuraton rather than a single tall unit gives me 4 shelves at convenient heights for plants plus 2 shelves on the bottom that I use more for storage of pots and fertilizer etc. I have lights hanging from the ceiling for the top shelf, giving me plenty of room for taller plants as they grow, and I put quarter inch dowels through the keyhole openings on the brackets to support lights for the lower shelves.
