Becca, I don't have this one (one of few I don't have seems to me

) but from all I read on it, you really are looking for a drying of the big roots between waterings. I have found the Angraecoides with large, white, thick roots want to go to white between waterings. Just my take on things. I am constantly moving guys around till I get the right combo of high humidity, yet drying, by moving certain 'chids in front (or in your case below) the fans. Hope this helps.
