I have 40 16" pots per zone, and have 3 zones setup on my Rachio system.
How should I enter the area, per pot or total area of all the pots? i.e. A=pi*r^2, so 3.14 x 8^2 = 201 sq in, or 1.4 sqft? Or should I multiple by 40, the number of pots? I suspect if I’m calculating the nozzle inches per hour for 1 emitter, then the area should be for 1 pot, yes?
Each pot has it’s own spray emitter (a bubbler that fans out the water to about a 3" diameter). The emitter puts out about 7GPH. How do I calculate “Nozzle inches per hour”? What is the diameter of a drip cup? Obviously the diameter of the drip cup determines the “inches” of water (small diameter, greater inches received).
How do I determine the available water (in/in) in the soil? Some of the pots are Self Irrigation Pots (SIP) so they store water in the bottom. Should I remove the SIP pans holding any extra water? The SIP is used to catch any extra rain water to reduce water usage.
What is “Crop Efficiency” and how do I determine this?
Each zone has different root depths (based off the age of the trees in each pot) and soil types, so that’s easy enough to tweak.
Thank you in advance for your insight.
P.S. it would really be great if Rachio would update their App to reset water usage. This has been a long time request by many users, which seems to go unanswered.
