Aerial Roots and Humidity Trays

[marco5011]

I have placed humidity trays under my Phals.
Now, some aerial roots seem to appreciate it to the point that the longer ones have managed to get all the way to the wet clay pebbles and as soon as they touch it they look much helthier acquiring a nice pale green color that spreads for a few inches up the roots making them look even bigger.
Question is: is this dangerous ?
Might this, in the long run, induce root rot?

If the plant chose to keep its roots that wet then let it go. This is not uncommon with many orchids. I have seen vandas grow down until its roots were growing in a pond. I have seen a cattleya that was growing on a rock extend its roots directly into the ground and grew in dirt so that it can no longer be removed.

It is not something you can force on the plant, but the plant can grow roots elsewhere if in wants.

Enjoy what is certainly a healty plant.
