It isn't that complicated, and for those with no techie inclinations, there are plastic containers that would make great orchid pots. They sell them in a House and garden supermarket here. About 3" deep, made to look like wicker baskets.

The point of all this is that it isn't the diameter of the pot that matters, it's the depth.

As Estacion seca says "What matters here isn't that the pot is small, but how far the most deeply-buried roots are from the air. A wide, very shallow pot gives the equivalent aeration to a very small cubical pot."

I look at small pots, and the orchids have very tightly packed, cramped roots. That makes me nervous, and I am trying to see if there is any real benefit from this, and so far no one has shown be that diameter has any influence on flowering, for example.

You can get the same results from your 4" diameter pot as I can from my wider pots. The difference is that in mine the roots aren't so cramped, and I can grow a bigger plant.

If course, if you are cramped for space, then small pots have an obvious advantage, but that isn't anything to do with the original question.
