I have a small curbed in area that I am going to sod. It is a rectangle 5 1/2 feet wide by 15 1/4 long. I went into Star Nursery to ask for their advice... they suggested one head on each corner and two on each of the long sides for a total of 8 heads. They said to adjust them to about 5 feet of output. To me, that seems like too many heads for such a small area. Does that seem correct?

Thanks for the advice...Chris
