We use these flat head spray nozzles that are specially designed for outdoor use. They deliver a pattern of water that is almost perfectly horizontal. The water is atomized, but only to a point. What makes these nozzles unique is that the droplets of water are tiny, yet just large enough to not be easily carried by the wind. Other nozzles don’t work because all of the water just blows away.
One nozzle can easily water hundreds of cuttings. We just keep sticking cuttings in the bed and as soon as we get out of range of the first spray nozzle we add another.
It only takes minutes to install each spray nozzle. If one spray nozzle is all you need, that’s fine. The system happily runs one nozzle.
The spray nozzles plug into plastic PVC piping that is hooked to a garden hose. The water is turned on and off automatically, as needed, by an automatic water valve which is controlled by an electronic controller. The controller is mounted inside of a garage or shed and plugs into a regular household outlet. Of course the outlet should be a GFI type of outlet for safety reasons.
If all you need are Flat Head Spray Nozzles we sell them stand alone as a package of five which includes the nozzle in the picture with the legs and the tubing.
