I am posting the link to the Phalaenopsis nursery in Oberlin/Ohio. These guys are the ones who started the Ice cube thing.

Nice gimmick!!
But to get your Phalaenopsis to spike - I have read this years ago, one can take the whole pot and water it a couple of times with chilly water, without getting cold water into the crown. I have never done it though, since it cools down sufficiently here to get them to spike.
