Adjust the dripper (or sprinkler) discharge by adjusting the control dripper.
Adjust the interval between irrigation events by adjusting the length of the polyester skirt.
Responds automatically to on-site evaporation and rainfall.

Bernie, Now it is clear how the water comes in between the inner and outer containers. However, the drawing needs a lot of improvements and also it is necessary to review the operation principle:
1. looks like the inner container moves upward with the inlet and outlet pipes, valve ad drainage pipe. This cannot be possible with rigid pipes: maybe hoses will work?
2. For one cycle it is clear but how you restart next cycle?

The cycle restarts after sufficient water has evaporated from the polyester skirt and the inner container has fallen to the low level.

The discharge from the adjustable control dripper is delivered from the lid of the container to the bottom of the outer container via the drain tube on the RHS of the diagrams. I will now post two additional diagrams: 1. ELEVATION at the end of the irrigation event, and 2. ELEVATION at the start of the irrigation event.

Bernie, can you provide more details? For example, it is not clear how and from where the water arrives between the outer and inner containers.
