Here are the flower pictures of two cultivars of Robert Strait..
A well done tutorial of one method of re-potting. There are many different ways to treat re-potting and this is probably the most common for hobbyist.
Try using coffee filters as a bottom in baskets to keep the bark in the basket. I personally use sphagnum in a very thin layer but many people would not feel comfortable with sphag.
Obviously this method would be too labor intensive for commercial use. Unfortunately we remove the plant with much more root damage and too often there is much more in rotting roots than FLBob's excellent plant. After removing rotted roots there may not be much left.
After cutting the plant into as many divisions as desired, the pieces are left on the bench (or in crates) for several days or weeks depending on how busy we are. The roots are left to dry and be cauterized by the sunlight. The plant responds by initiating new roots.
I am not suggesting anyone use this method, it is scary for a hobbyist. I only wanted to point out the ability of orchids to handle much harsher methods.
