Why make 4 5X5 4ft sections when you can make 2 5X5 8ft sections? I did it this way a couple years back 1 8ft rail had tomato and pepper plants in 11 3/1/2 inch net pots. The other 8ft rail I had 17 2inch net pots mostly for strawberries. Both ran off the same reservoir I used a splitter to feed both rail sprayers at the same time. I place 1 sprayer between every 2 net pots. The below thread link has pic of both rails.

Pic 1 below shows how i get the PVC into the rail. I use a rubber grommet.

Pic 2 is look inside the rail for what I use as a drain back to the reservoir. I bought this piece at Lowes/Home Depot in the electrical section for less than $2 1 side has thread (male) and the outside piece is female. I drilled the openings so the water could drain.

The end covers for the rails I used "Food Grade Caulking" to seal them in place to prevent leaks. I also used the caulking for the inside drain again to seal so no leaks. Don't use any other caulking it's toxic except for food grade.

Last but not least yse you need a strong pump for the sprayers but you will be watering the plants less than you do with Dutch Buckets.
