I've got some moss that I don't want in a tank anymore. But, I might use it in another tank. Any tips for growing it? Should I grow it emersed or in a container with some ei fertilized water? Also, I have various windows to grow it in. East, west, north, south facing windows. The east and south get the most sunlight while the north gets mainly ambient light. The west gets a few hours of direct light in the morning.
