I have a garden (residential) in my back yard with 4-5 raised beds. For the most part they are all different sizes. I have installed pvc in most gardens. The pvc is drilled at the same intervals with the same diameter holes ,spaced the same distances. When I attach the hose to the fittings for each garden the water needs to be turned on a different amount to achieve the desired application. This makes watering a time consuming event. Is there a way to regulate the different pressure requirements for different size gardens from a normal residential garden hose. Sorry for the lack of technical information.
