I made the following short video showing how everything works. If you are and DIY handy man, you know how to do it right away after watching this video:
I used a simple airlift pump made with a T-connector to feed water from the top of stacked grow trays, creating a water dripping flow. It is based on what is shown below with one exception: I added a one-way check valve at the water inlet so that it only allows water to come in and air cannot get out in an opposite direction.
See how simple an airlift pump is!
This photo shows it all, very simple to make
