Lighting im gonna get the big long tube lights for like a Grage and run them on a timer they fit perfectly under each shelf and provide ample light as wellI noticed you built your racks out of wood. We started with wood but are slowly canging out to pallet racking. It comes in great widths for setting up fish rooms and snaps together real easy. It will last forever and not rot like wood can. We found ours second hand and very reasonably priced. Did you look into it or you still could if interested your set up looks good. How are you planning on lighting it.
