This will be my third season using Rachio. Up until now, I have been unable to figure out flex scheduling. My zones so far have all been small and drip; I’ve just used fixed watering times for the most part. I’ve been unable how to accurately figure out how to set up my zones so the water correctly with Flex.
I just installed a new yard and would like to set up Flex schedules.
My new yard (small I know) is 156 sq ft.
It is watered with 182’ (175 emitters) of Rainbird XFS-06-12-100 sub-surface drip irrigation ( http://www.rainbird.com/landscape/products/dripline/XFS.htm ) pressurized at 20 psi.The dripline is rated at .61 gph and a working pressure range of 8.5 to 60 psi. Is that .61 gph per emitter and should each produce that, regardless of what the working pressure is, as long as it is withing the specified range, or will it emit less at 8.5 psi than at 60 psi (or my working pressure, 20 psi)?
What spray head type should I use? None of the choices are drip line. I’ve selected emitter.
What values should I use for Available water? What units are these?
What about root depth? Is this effected by the fact that the drip line is below the roots? I think I am around 4" deep below my cool season grass sod.
What value should I use for Nozzle inches per hour?
Lastly, how do I determine what to use for “Allowed Depletion”, “Efficiency”, and “Crop Coefficient”?
This is new sod and I would like to apply the recommended 1" per week and don’t know how to set up the zone so this is done close to correctly, with either flex schedules or fixed schedules.
Thanks in advance!
