Growing Hoya sp. Sulawesi No. 1 Part Two

I next re-rooted what was left of the plant in my regular peat-based, chunky potting mix. It grew slowly for awhile and then I once again lost the plant to root rot, or who knows what. I was about ready to give up on it, and decided I would re-root it one more time and I used pure coconut husk this go around. Below the leaves of the plant, which come in dark red and eventually fade to matte green.
