Assuming no major rain (but not drought) and summer temps what is your ideal watering schedule (freq and duration)? Please include other relevant data like type of grass, location, etc.
I live in North Florida and it seems like 20-40 min every 3-4 days is just enough to keep my centipede/Bermuda/Bahia out of dormancy. Its been 90-95 every day here with very scattered tstorms. Flex comes real close to this on average but I am thinking of upping it to every other day (its nice having a well sometimes)
