Oxankle at the beginning of the thread was inquiring about chopped sphagnum and I found that it was impossible to find that particular 'grade' of sphagnum. The finely milled stuff is available and is good for seed starting. Due to its anti-fungal properties the chances of damping off are minimized.
I am testing a 50/50 mix of chopped sphagnum and perlite for a cutting rooting mixture. Sphagnum works very well for air layering and I think that it might do well employed this way. I am "chopping" it up just a bit so that it will mix better in the perlite. Left alone as long stranded material, it will not blend as much. If I used the finely milled stuff it might make too compact of a mixture.
So, the best 'grinder' that I had at my disposal was a food processor. It only does a small amount at a time but I figured out just how much to run it so that the moss did not turn into dust. As mentioned earlier, I did moisten it - soaked it in a large bowl and then squeezed out the excess moisture.
