I live in Arizona and it's not really hot yet but it's starting to get warmer and I noticed my rye grass is starting to die off and everybody else's is very green.  I think it's because netro isn't watering as often as it should be when it gets warmer. I'm aware I can set a manual schedule but that kind of defeats the purpose of why I bought Netro. So what I'm saying is I think an algorithm needs to be adjusted so hot dry climates get a little more watering for winter grass that's still in season before the Bermuda comes in.
