I figured out how to resolve the problem so all I need is 2 pieces of 1" sq tubing 4'3" long and it will sit as I had envisioned it.
So I have added the flood tray, some gravel (need more) and water with the orchids not in bloom. Only one phal under this lighting to see how it does.Also shown 4 oncidiums and 2 catts (including my immature one).
My fans will be in on Monday. Hopefully they can survive 2 days without them. Note the sectioned trays. These were gathered from one of my local nurseries. Free for the taking. I think they will be quite useful in my setup here. Now I can water without moving them.
