So here are two in question, one is a mexican bird of paradise, and the others are orange jubilees. Not sure of their desert hardiness, but I don't think they are getting enough water.
Current settings: Each plant has one 2 GPH emitter, Rachio runs for 1h2m with a nozzle of 0.70 in/hr.
Rerunning numbers: Each plant has one 2GPH, but using the 3' canopy for these, I get 0.17 in/hr. 2' canopy will produce 0.34.
0.17 in/hr gives a run time of 4h
0.34 in/hr gives a run time of 2h.
I think i'm going to bump the nozzle to 0.34 in/hr to see what happens. I worry that 2gph may start to cause overflow, which I've noticed before with long run times.
