Hoya lithophytica Is Not The Easiest Hoya To Grow

Even when grown it the correct mix and the right container, Hoya lithophytica will not respond well when grown in a typical household environment.  In my experience it declines unless grown in high humidity, very bright light, and warm temperatures.  These conditions can only be provided in one of my grow tents, so I can’t recommend this plant as a houseplant for the windowsill.
