It breathes. On a loop.
Air in
Your aquarium air pump sends a slow stream of air into the dome. The air collects under the dome and pushes the water in the gravel down.
Roots breathe
The water drops below the gravel. For a while the roots sit in damp air, which is what roots want.
Water returns
When the air reaches the reverse bell siphon in the base, the siphon trips and lets it all out in one breath. Tank water rises back into the gravel and stops there: it wets the roots and never reaches the leaves. Then it starts again.
