DSM is, as Jim said, Dry Start Method. I think Tom Barr came up with the term DSM. It's mostly used for low height foreground carpeting plants like hc and hair grass. Because these plants grow 8x faster (according to Diana Walstad), it becomes a viable way for getting them established before introducing water.chris_todd wrote:What's DSM stand for?
