I use pillow moss in my viv. I removed one or two heads of the stuff from my greenhouse, pulled it apart as best I could with my fingers and spread it around the inside of the viv on a bed of dead long fiber spaghnum moss. Grew like a weed, no milk or cookies required. If you don't have live heads to pull apart just buy some good dead long fiber spaghnum (not new zealand type and not the cheap stuff in the green bag) tear it up, mix with dead peat moss, soak it and place in a standard PDF clear shoebox under good light. It will grow, this is where all mine came from. By far the fastest way is from live heads (growth points) though.
