It took me longer to get into town than I thought, but I have a picture.
It's not "done" yet. I need add a light fixture to the bottom shelf. I also plan to zip tie those wires to neaten them up. I'm going to attach a power strip to one of the uprights so everything can plug into the strip and I have only one cord going to the wall; and I have to add the shelves. Right now, I have two boards that I salvaged from a bookshelf unit on the middle shelf to hold some trays (seedling lettuce, spinach and venus flytraps), but I'm going to cut a sheet of plywood into proper shelves.
(The black drape is just to reduce background clutter so the unit shows up better.)
