Thanks! I’ll look into the international issue, I see other posts on this now that you’ve alerted me to this.
As per the flow I’m completely lost. I have a hunter drip,one, single run, under a single row hedge. Line spec is 0.4gph, with 12” spaced emitters. What I did was to try to say that in one hour my system should provide 0.4 gallons on a 1sf zone. Translated to liters and centimeters it would mean that it delivers 1,5l on a 900cm2 area.
