This started in a topic by JD about potting mixes, but thought I would emphasize it.

"After a prescription of daily doses of 3% peroxide, 10% bleach solution, and cornmeal solution, the pencil thick group still had an uncontrollable case of MKS (Mold Keeps Spawning). On a whim, I piled some moist Sphagnum at the spawn site on the troubled cuttings and lo and behold, to date, the mold has been halted. Hooha!"  JD

If the moss has some ability to inhibit mold - I wonder what would happen if you put the moss in a blender with warm water, blended, strained out the solids and used the resulting liquid as a spray directly on the cuttings? Might be the new "moldicide".

Jon,
Like I replied on JD's post.

I think it is a good idea and worth a try. It should work.

I also wonder about this, but I have this to add:

Take some of the moss, wet it, and put it in a sealed baggie away from light.  See how long it takes before it molds.

In my case, the moss on top of my soil took about 4-5 days of 90% humidity to start forming the blue-green mold with white perimeter.

I use the wrungout water from Spag moss and
put it in sprayer to mist cuttings as needed
and also use it on potted plants when they need
watering.
Maybe I'm just lucky but I have no problem with
mold or rot so far.Before I started doing this I did
have some mold problem.I use Dans improved baggie method with a little moss added to bag.
