Having read the blog post from Chris about his water savings, I was interested to see what the suggested run times for my zones were going to be. Especially as the post mentions a 15 minute time being split into 3 lots of 5 minutes, which makes sense.
I’d just increased the run time slightly on my previous controller, for 2 cycles of 9,7,7,7,2 minutes for the 5 zones, 3 times a week, or 18,14,14,14,4 minutes a day, 3 times a week. The 2/4 being for a small set of shrubs that drown with more than that.
I’d input all the criteria; flat, clay, rotary, grass, etc, and got, after digging around in the app until I found them, these run times, for 3 times a week:
45,45,45,45,20. Bloody hell.
With the newer features such as cycle soaking, I was expecting it to reduce the times slightly(I could also have accepted a slight increase, but in general, I was thinking I was fairly conservative), not triple them, especially as I’d last set the times in accordance with Parker Water guidelines some years ago.
While I may not have the greenest lawn in the world, it’s kept the grass alive, which is more than can be said for some of my neighbors. I’d also say that my run times are similar to others in the area, and that the soil is certainly getting wet - in some places it’s still getting waterlogged, something I expect the cycle soaking to help with.
So, what other ‘real world’ changes do people have, is this reasonable for the area (Parker, CO)?
Also, how does changing the soil type affect this? I played around with all the soil types, different sprinkler heads and so on, refreshed the results…and no changes to the run times. Am I missing something obvious, looking in the wrong place, or just being a bit daft?
I appreciate that it’s making some general assumptions - so perhaps another suggestion for the box; input yard/zone sizes with number of sprinkler heads per zone to give a better indication of the amount of water being delivered?
