I have little problem understanding the irrigation requirements. If you see the first post in this current thread the irrigation requirement has increased in a day inspite of the person watering and has a 'water per cycle' of 0.75. If this keeps on increasing each day does this mean that the watering is not enough? What happens when it rains does the irrigation requiments adjust itself? Do we have to do a Reset Variables after Cycle Complete?
