I know this is a topic discussed ad-nausea here but I’m still stumped at what happened to me.
I’ve been using flex monthly for about a year with the default settings in the advanced area. Most of my zones would run for about 9 minutes pretty much every day.
I followed the steps in:
I chose sandy loam for my soil since it is a new build, but the general soil in the area is flagged as gravelly loam so I figured that was the closest match.
The turf is mostly bluegrass and fescue so I left it at 6in depth since my research showed that fescue can get pretty deep.
I left the available water and efficiency alone and changed the Kc to 70% (based on what I researched)
however, instead of doing the catch cups, I measured out the area of each zone and got the GPM from my water meter. For a number of my zones, it drastically lowered the PR down to .5 or less (instead of the normal 1 or 1.5
these adjustments moved my flex monthly schedule to run for almost 350 minutes now (starting at 11 pm and running until 6 am) and flex daily would be over 550 minutes!
- does this sound right? was I watering my lawn wrong this entire time
- Am I getting accurate PR’s with the area and GPM calculation, my rotors are not all doing 360
- I’ve seen a few other threads that recommended that I start with a shorter root depth and work my way up since I’ve probably had it too shallow for too long
I’m trying to balance having a great looking lawn and having a wife that won’t kill me for a zillion-dollar water bill.
