I know it looks nice as a top layer but is it worth it to try to track some of this down and pay the extra amount for it? Is it easy to keep alive or does it die easy? How long will it stay alive before it dies? Does it keep the plants damp, moist all the time? Does it make you use more water or less because it retains more water? Let me know your thoughts on it and where I could get it. Is it possibleto grow it somehow rather then having to keep buying it? Or will it come back with the plant when it comes out of dormacy?
