Hoyas have a reputation for being slow growers. While this isn't always the case, it does require a consistent and stable environment to have a pleasant growth and development. Any rapid change in water, humidity, or temperature, as well as any other stress, could cause these hoya plants to go into partial dormancy, halting their growth for weeks or even months. As a response, it is not encouraged that you move the plant around your house too much, or that you place it in a high-traffic location such as a hallway, or that you place it near drafts or unexpected temperature and light fluctuations.
