One more update on my system -- I mentioned earlier that I was not sure if the controller I bought would work with fewer nozzles due to flow volume requirement. I have found that it works fine running only the 7 low-rate nozzles from Charlie's GH underneath the bench.
I am glad to have run nozzles both overhead (2 rows) and a row underneath the center bench with our recent weather. It has been very humid with a tendency to become partly cloudy by mid-afternoon. Running all the nozzles was getting my plants way too wet under those conditions. And, of course, due to the clouds the GH was not heating up as much either. So I cut off the overhead lines and just ran the under-the-bench nozzles. When I got the chance I hosed down the part of the floor those nozzles didn't hit, but even if I didn't the GH temp stayed reasonable due to evaporation from the gravel and air circ from a couple of box fans on the floor.
