When root rot is seen thru the glass...

[greenpassion]

This may be a question for Ray...I have all my orchids in S/H. I have had great sucess with this, even to the point of being able to take a keki and put it directly into S/H and it never missed a beat. However, despite how well these guys are all doing, I have seen on some, that there are rotted roots seen thru the glass. (My plants are in clear glass containers) These orchids in question are all rapidly putting out new root growth both inside and outside the pot. The roots that are or have rotten are from the initial introduction to the S/H. Sooo, my question is this. Do I have to un pot the plant and trim off the old dead roots? They are all doing really well, and due to the clear glass I can see the vigorous new root growth on each one. Will the dead roots harm the plant, or get 're-absorbed' eventually?
