In this study, how capsule and spore sizes affect the height to which spores are propelled were measured, and how spore size and spore number of discharged particles relate to settling speed in the aspherical Sphagnum spores. They take much more time to get growth than a slurry, since you’ll be waiting for spore germination and the following plant development, as opposed to growth of live moss pieces which begins immediately. Since mold spores spread through out the entire batch of sphagnum peat moss, there is a possibility that it may still produce more mold in the future.
