Got a chance to swing by @ssayet place to help him with his setup. This post is some info for general knowledge, as well as for Steven to see what changes were made.
I started messing with the grass, because that was easy. Soil set up looked good and zone type were fine (rye grass overseed). I set the root depth to 6", which is what I found to probably be pretty close in my research, and works well for my grass…I was able to identify that he has Hunter 10A Red Pro Adjustable nozzles, so I adjusted his Nozzle Inches Per Hour to match the Hunter literature of 1.93". If Steven really wants to get geeky, I’ll bring my catch cups next time, but this will dial it in much more than the default spray head setting. Similar to my findings when I blocked out certain days for watering, (not watering Thursdays and Fridays, landscaper comes), it looks like there may be a couple back to back runs some weeks to keep the moisture level up thru those blocked days.
Now, the drip is where things get a little more tricky. Steven has 1 drip zone for the front and back of his yard, which contains both shrubs and trees. To further complicate things for the short term, the front yard is relatively established (October 2017), but the backyard is less than one month old. Currently, the shrubs each have one 2gph emitter feeding them, while the trees each have two 2gph emitters. I adjusted some settings in the zone, but I’m looking for input on what to set the zone type to (I currently set to Trees), and what to set the root depth to (mixture of plant types and fairly new plants, so I have it set to 15"). Once the changes were made, Rachio is looking to put down 1.13" of water. So after plugging this info into the amazing @azdavidr Drip Emitter Calculator for Precipitation Rate & Area, I hit a bit of a wall.
“Water Use it Wisely” Table for reference:
There is a big disparity between the required PR’s for trees and shrubs given the current size of everything. Currently I have the “Nozzle Inches Per Hour” of this zone set in the middle of the two at .45". So tomorrow, the drip will be set to run for 2h 31m.
Now, if Steven were to change the emitters on the trees out to 4gph (remember, each tree has 2 emitters, so totally 8gph), something REALLY interesting happens…
Anyone have any input? @Modawg2k @sunny @Sprinklerman
