 So, no, there's not a set number on that. You know, a lot of that, some of that has to do with your landscaping. Are you on a hilly landscape or are you on a flat landscape? And can you do a test so that way people know how much water they should be using or what kind of sprinkler system they should use or sprinkler head? As far as a sprinkler system, I think that's going to be whatever's probably already there. If you're building something. Well, I say like if you just have one that you just plug into the water hose and throw out in the yard.
