I have a yard with a grid of evenly spaced Hunter rotors. I get some dry spots during the hotter days. I believe because the rotors are evenly spaced and nozzles are matched to their respective arcs, that I am getting excellent coverage. Therefore I suspect these drier areas are sandier areas.
Any 'best practices' in improving coverage on these specific areas? I am thinking of increases the nozzle size of a couple rotors and then reducing the radius back down to the original size and therefore getting more water over the same circle and hopefully more within the circle. Thoughts?
Also, I have some areas where the grass gets dry within a foot of a spray head...as if the spray goes over this area and unfortunately this area is a 'strip' area and doesn't have opposing spray heads for overlapping coverage.
