Sam, was that Hydroton you were using in that pic? Were you growing it hydroponically or semi? I've seen a lot of nurseries using the Hydroton as their potting medium, grown regularly, not s/h and especially on Phals (with a little coir added) and they swear by it. I have a few Catts. in the Hydroton and they're not complaining either.
That neo in your pic is gorgeous!

OK, I see you answered these questions in post #76...I wasn't reading in sequential order. So, ignore what I've asked.
