Sphagnum moss is a moss that forms in low nutrient, wet areas. As sphagnum grows, then begins a slow decomposition, it forms mats that sometimes reach hundreds of feet thick. You want this moss before it has started to decompose. If you're not confused yet: When it's suggested you use sphagnum moss as part of a potting mix, or in your case, an air-layer media, it's the long-fiber sphagnum moss that was originally live sphagnum moss that was harvested and dried - like the stuff in the paragraph above, before it begins to decompose. When we say, "Use sphagnum peat", we mean: Use the dried and partially decomposed product, not the long fibered stuff. What you want looks kind of like a nearly intact moss plant. The other looks like dry or dusty decomposing plant matter. You should be able to buy sphagnum moss at most big box stores in the potting medium section (in small bags). If you can't find it after another look, contact me off forum & I'll mail you some. ;o) Al

I am glad I saw this thread..That is my next method.. I am rooting some in a sunny window as we speak but it's winter and boy does it take longer for the process without lights and a warm room. I too was wondering how much Spagnum Moss and how much water ratio with the added ingredients? Mike, thanks abunch.I was enlightened! Mike

I've found these in garden centres, or in greenhouse nurseries, or in places that specialize in tropical plants. Now that we are in April, many places will start having their garden supplies out for sale and so perhaps you will find it easier to locate your supplies. Even Home Depot,or Walmart, or Lowes should be able bring in some supplies. Good luck.

Hi Dave I think vermiculite is now frowned upon because of health issues it can bring up. I remember this being in the news in the last few year. The dust is dangerous to inhale. I use straight Perlite to root back bulbs or pseudobulbs. No over watering please keep on the barely moist side. It takes a long time, but it does work for at least 50% of those I've tried. Then you have a plant for a 'spare' or to share. I use perlite also in the mix for terrestrial growing orchids, but it is 1/3 the mix or less with charcoal and finer bark. I don't use it for any epiphytes as the mix needs to be open airy drain well. Good luck! Maryanne in chilly WMass
