Hoya sp. EPC-610 aff. verticilata is another Hoya that just sat there all summer without growing a leaf or new bit of vine. It also got the jet spray treatment and a complete repot in hopes of bringing it back to life.
A word on the clear pots and why I have not used them much in the past. I always felt that roots did better in the dark, but with all of my root problems, I finally gave in so that I could better see what is going on in the pot. Another problem with clear pots is that they quickly green up from algae, making them worthless for viewing in a few months. I am hoping to combat this by keeping them in a dark cache pot.
