Looks like a great setup! With regard to the 200 Watt LED over the cattleyas, are you using the full power of the light, and if so, are the plants tolerating the light? I have an 8' x 4' grow tent in my basement with two 3' x 3' trays. I use one Spider Farmer 100 Watt LED over each of the two trays. My PPFD measurements are consistent with the values recommended by High Desert Orchids.
