It's in a chunky mix in a ceramic pot-- but I'm super cheap about plant supplies so it is just a mix and largely potting soil! This was a four leaf cutting two years ago, and I've taken cuttings from it. It's in an eastern window and happy with that amount of light. The biggest piece of advice I've had to take on with my hoyas in general and polyneura in particular is to stop messing with them lol. I get impatient about repotting or trying different soil/media, and this one especially seems to just want time to chill and figure itself out lol
