Hi JMF, welcome to OB
I read that thread too. I have a large Vanda that I've had for about 8 years that has never flowered. Poor old thing just struggles along. Anyway after reading about the vase culture I decided to give it a go. It's been about a month and the plant is starting to look better. I used a big Moccona coffee jar, do you have them over there, they are storage jars with a glass lid with a rubber bung attached?
I cut the bottom out of a squat plant pot that would fit snuggly into the mouth of the jar. I put some coir fibre into the bottom of the jar with about an inch of water. I pushed my Vanda's roots through the pot and down into the jar. The pot sits just inside the mouth of the jar, the roots extended down into the jar to just above the coir. I pushed some more coir into the pot around the top of the roots. I spray the aerial roots every day and the water drips down into the jar over the roots. The water at the bottom of the jar keeps the roots in a humid environment. Once a week I water all my orchids. I fill the jar up with weak fertilizer solution and allow the roots to soak for about 10 minutes. Then I pour it out all but that 1inch at the bottom.
Here is a pic of the set up (dogs posing in the background!
