@Psilocubensis, Ah ok, they're just on cheap 3600 L/H air pumps that have 6-outlet manifolds. The pumps are suspended to keep the vibration down. The air domes themselves are the official autopot brand, and are also quite inexpensive. They definitely fit any type of pot or smart pot, probably 2 gallons or greater. These also have a simple, cheap aquarium air pump check valve in each line to prevent any solution back flow.
