I need a controller where different zones be controlled by the Rain-detector. Here's my situation... I want the lawn to be controlled by the rain-sensor. But, I have flower-boxes that do not get rain, and I still want these to activate not dependent on the rain-sensor. Help?
I currently have my irrigation output water set to 6.0 pH with the use of sulfuric-acid; But my soil tests show a level of 7.1 pH. I prefer not to add anymore sulfuric-acid. In addition, I applied sulfur to the lawn last fall; By now it's effect should have lowered the pH. Suggestions?
