Rooting a Cut Dendrobium Cane?

[Becca]

I recently saw on ebay a seller who is offering an established dendrobium which is a rooted cane cutting. I didn't know this was possible. I emailed the seller and asked them how they did this, but of course I didn't get the answer I was looking for. To me, a rooted cane cutting would be cutting the stalk off of the rhizome and trying to root it with possibly some rooting hormones like you can do with some house plants. I thought if you cut a dendrobium cane off and laid it in a bed of sphagnum moss that it might send out keiki's....do I just have it all wrong?
