Moss... peat moss?
A coincidental happenstance: on another forum someone asked about sterilizing peat moss.
(I think he meant pasteurizing.) If you are grinding it up, I assume you talking about the very raw form (light in color and undecomposed), as opposed to the brown sphagnum peat moss one normally finds in bales at nurseries and big box stores. So it ends up like milled sphagnum after you grind. Right?
In both pictues:
Left =raw sphagnum
Right =milled sphagnum
More available is smaller bags (quart size) of milled sphagnum. I thought I had some to show, but no. It is "cleaner" and much more (light) golden in color.
Have you any comparison observations of pasteurized versus non treated sphagnum? There is always some contaminate organic materials, like sticks, in with the sphagnum. Is this what you're worried about? But I wonder if the heat would "denature" the fungicidal properties (and other good qualities) inherent in raw sphagnum -- things that can really make it a "wonder drug" of the plant world. Any thoughts?
The advantage of builders sand is the variety of particle size.
