I know this is an old thread, but I am in the exact same situation… currently on flex monthly, and moving to flex daily. I hate the fact that I have to create another schedule, and can not just modify the existing schedules.
I have set up my yard map finally, and have not committed to creating the new schedules yet. I have a couple questions before I continue:
-
What is available water in/in for? I am using municipal water, so the only limit is the amount of money I am willing to spend.
-
What is crop coefficient? and how do I determine this item?
-
My nozzles are rated at Gallons per minute, so how do I convert that? I did the cup testing 20 years ago with the original rainbird controller, but I have no idea what those values are now, and I am not really eager to go thru all of that again.
-
Similarly related, I have a mix of various fixed nozzles in my zones: 1/4, 1/2, full, adjustable throw patterns, as well as varying foot width (8’, 10’, 14’) nozzles, and I have flower beds in the same zone as large grass areas. How do I compensate for that?
Any suggestions, explanations are appreciated.
