Tending Hoyas in the Dark

It is tough this time of the year to tend to your Hoyas as it seems to be always dark.  Here is a photo of three plants from my bedroom. Pictured Left to right: Hoya griffithii,  Hoya chinghungensis, and Hoya siamica.  These plants can tolerate lower temperatures, and as you can see from the thermometer, it is cool.
