I received a gallon-sized ziplock bag of live LFS last Fall and I am currently using at as a growing medium for a variety of leaf cuttings / pullings (D. filiformis, Mexican pings, VFT's, and Cephalotus follicularis.
The moss is growing nicely and seems to be doing a great job with providing good growing conditions for the leaves.
It is kept wet and is at a SE-facing window sill. The tips of the moss are turning dark. Is that normal? Is there too much light? It seems healthy, otherwise.
