I'm in the middle of expanding my putting green in the back yard of my house, and we've made it to the exciting point where the height of cut starts to come down. I recommend that you wait a fair amount longer than I did; however, it looked like it was ready so I sent it. The green is now brought down to a quarter of an inch and was looking pretty good, all things considered. Make sure you stick around to the channel to watch as we continue to mature this back yard putting green.
