The growth potential converts air temperature to a 0 to 1 (or 0 to 100%) scale. Of course, there are a lot more things that affect actual growth, including light, nitrogen, and water. I discuss these and why I'm not so convinced that adding a light factor to GP makes it more useful.

What is The Doublecut with Micah Woods?
I discuss turfgrass management topics, usually starting with a blog post, sharing supplementary information, stories, and the reasons why I thought the topic was worth writing about, and worth reading about. Thus, a doublecut of these topics. This covers grass selection, playability, and all the work done to create a certain type of turfgrass surface.
