I use wet seed in unwatered but somewhat damp topdressing mix that was kept under a tarp and remained somewhat moist. Golf courses are mixing large batches meant to be used over a several day or weeks period. They don't want it all popping in 3 days. Perpetual care kind of thing. Also, much of it is put down by people playing golf rather than maintenance workers. It has gotten to be competitively politically correct. Elves come by the next morning and fix the repairs
Great work and photos in that other thread mdlwn1!
