At least you know everything works and you'll be ready for next season. Good job on the setup and filling us in!!
I'm actually interested in the PVC tube rigs. Seems like they would be easier to construct and work with, but may require more precise level control.
Years ago, I saw one big producer with a rig like this, and it seemed fairly simple. Can't remember the PVC tube sizes they used for various plants tho. Something to spend a day or two looking up.
