First I had to put in the time – three years to be exact.  I tried all kinds of methods and what finally worked was exposing it to thee different waves of plant lights.  I used HPS, T-5 fluorescent, and LED lighting.  I needed to let the plant go wild and not wrap the vines until after it flowered.  It bloomed in the shade of the grow tent, six feet in the air with the vine wrapped around the cord to one of the lights.  It was watered and cared for as any other Hoya.  It grew in very high humidity and day time temps of around 80°F and Night time temps of around 55°F
