I haven't had much success with my DHG, which was planted about a couple of months ago. However, to be fair, I've had to replant it a couple of times, and I also don't think I was giving the DHG enough light. I had too many floaters blocking the light. I think I hardly have any green blades anymore. I rescaped my tank this past weekend, and there's more light hitting the DHG now. I'm hoping that it makes a comeback. With that being said, I'm not holding on to my dream of having a grass carpet. I got some glosso from an RAOK, and I'm looking forward to planting it and having it carpet. As I understand it, glosso carpets very quickly given the right conditions.
