Ah. Very nice man. The long fibered sphagnum moss seems to be the way to go with them. I only had mold with the first batch in reg potting soil. I probably would not have started all this if I had to start from scratch. My mom used to be big into growing flowers so I had access to lights pots and grow tables and a small greenhouse that she is no longer using. It may get old after a while but I've been enjoying it so far.
