Growing Hoya vangviengiensis Part Two

I had many stops and starts with this plant over the years. It would go months at a time without any growth at all. I suspect that there is some root rot that has gone on with it at times, as it is in far too large of a pot, which I am trying to move away from. I will go into extensive detail about how it lives in nature, and apparently it is totally epiphytic in its endemic habitat so the large pot had to be detrimental to it.
