With root culture, is the plant mostly just perched in an empty vase, and you pour the water into the vase for a soak period, then drain the water off again? Interesting! Are all of the roots made to go down inside the vase, or do any of them hang over the sides? I'm trying to picture it in my mind, but may need to Google an image to be sure.
That may well be worth trying in my situation! I'll have to remember that.
