Those new roots on the Vandas are beautiful! That is very fast for response to the new conditions. Oh, that would be wonderful for C. aclandiae to grow like the photo... Good luck!
In the vanda area, with the spray, you have done a great job of controlling the mess. Does the water just evaporate from the plastic pan? What is the floor material? It looks like wood, but I wonder if is ceramic tile. Certainly it gets a little wet sometimes.
