Multiple Irrigation Schedules
Issue
You want to have two or more Irrigation Schedules.
Solution
The Irrigation Schedule will not include anything on a frozen layer. So you are welcome to freeze either the drip area layer, or emitter layer, to prevent certain items from appearing on each schedule. Just note that when you regenerate any such schedule, it won't remember which layers were frozen when you first created it. Therefore, we recommend creating layer states with certain layers frozen as necessary. See our instructions for freezing / thawing a layer.
