Thanks for the link, Laura. My question was more about what to do leading up to blowing out the lines for the winter though.
Franz, I set it up to use flex daily (three lawn zones) from the start and it’s worked well for me. The defaults worked but seemed to be over-watering just a bit. I found a post here about increasing watering by increasing the crop coefficient, I went the other way and it was better. Some more tweaking will be necessary next year. My drip lines are set up to run a fixed schedule because I wasn’t very successful at getting a flex schedule to work. Most of that is because I only have the one drip line and it’s covering flower beds, shrubs, and a vegetable garden - not a good mix.
Silharder, from what you said it sounds like the controller will handle the transition to fall for me. I guess I was concerned that I hadn’t seen the watering frequency changing, but I hadn’t considered the extremely hot September we had. Thanks for the info. BTW, I’m one of those folks who will drag the hose out in winter to water the lawn if there’s not been a lot of snow.
