We’ve tried to make this easy, but are always looking for ways to make the process better. Unfortunately there is a lot of complexity. We are looking at ways to abstract more of this away.
This is correlated to water loss.
To truly measure you can do a catch cup test (they call the value distribution uniformity) or just use our defaults which will work.
Quick article on efficiency:
The higher the efficiency, the lower the duration to fill your zone using flex schedules.
If you want to modify watering frequency you can adjust allowed depletion. If your frequency seems OK, I would not touch it.
If you want to modify duration, you can use the water drop or pick a different nozzle type.
In the near future I want to allow modifying frequency with something similar to the water drop. Easy for us to do, just need some time.
Yes, or grass is browning a bit. Back off duration if super lush, or mushrooms.
If frequency is OK, I would leave this alone unless it is watering every day or even every other day and just focus on duration. The ultimate goal is to have longer periods between waterings.
So why is allowed depletion so important? You have heard me echo the plea from horticulturist to water deep and less frequent. It is true, plants are healthier and more stress tolerant when watered deeper and less often. Roots need air; when we water too often, roots struggle to get air so roots stay close to the surface. The concept of deep, less frequent watering is tied directly to Allowed Depletion. As water evaporates from the soil, moisture is “Depleted” from the soil. Irrigation should replace depleted soil moisture once the soil has dried out to an allowed level.
We have monthly reports in the app, but have not correlated this to weather yet.
I think once it is dialed in everything works great. Yes there are a lot of levers, but hopefully you don’t have to tweak too much. We are working on abstracting this more. Starting with one or two zones might be easier, than apply those settings throughout the rest of your system.
Hope this helps
