As the new sod roots in, I plan on adjusting the root depth, and possibly other parameters. How does Flex and As Needed adjust? My present understanding is Flex will dynamically adjust, but As Needed will not. True?
Root zone depth will affect flex immediately, with water as needed it would be reflected in frequency for the current month of watering (if you've changed it enough), and frequency and duration when it is adjusted at the top of the month.
Hope this helps.
