I'm going to be a troublemaker but those ET controllers all over the place are starting to get on my nerves. I've decided they are nothing more than a dirty band-aid. Spent a lot of time talking to the moisture sensor folks and they can make a much stronger argument about real water conservation results. What difference does ET make? All that is important is what the moisture needs of the soil and plant are. I'm starting to see a better way than yanking perfectly good controllers and putting up an ET controller. Bring back the RC-7. give the customer a controller they can use and soil moisture readings.
