Great read. This is our first year of fully using GR so guide inputs. Our course is predominantly Pencross Bent and I've found a GR of 0.4 to be ideal for our needs. It is enough to keep up with ball marks and can withstand the heavy traffic on our course (upwards of 400 golfers on our busiest days) with minimal need for verticutting, grooming, or Topdressing. So far this season we've applied 0.6#N/1000sqft, trinexipac @ 250GDD application interval, verticut once, light topdress twice to a depth of less than 1mm, and 1/2" hollow tine to a 3.5" depth with topdress to fill holes and 1mm on the surface and greens are better than ever.
