I have a Rainbird ESP-LX and would like to water 1 inch *every other week* to reduce water usage to a minimum. I've read the manual for the controller, and I'm about convinced that there's no way to do this--I think I'll be forced to water every week because I can't see how to program it for every other week (or else activate it manually). Does anyone know of a way to program it that I'm overlooking? Many thanks!!
