Finished up the manifold and also the plumbing to Tower 2. Put a cap in line where it will extend to Tower 1. I used the darkroom timer and did an experiment where I watered the bench for 2 cycles, each of 15 seconds. My future test will be a 10 second cycle. Eventually I will monitor shelf moisture but the goal right now is vacation at the end of the month. Dinner was Pad Thai from Whole Foods enhanced with chicken ala Libbie.
