Here is an update on all my small plants and a few big ones repotted in this system. I'm using the top aquarium gravel to keep the dust from the perlite down and to slow down evaporation of the water reservoir at the bottom of each cup/pot.
So far the smaller plants that were potted earliest are showing new growth. And the larger Stapelia in the back left is starting to stand back upright.
Hopefully they do better than before. The roots on almost all of the Stapelia types were either rotted or dried out so I had to clean most of them.
