Ah okay, then, good thing you removed the soil. Definitely not a terrestrial..it loves being moist, but loves the air circulation at the root zone.
In another orchid forum I go to, they often do semi-hydro, using a container with two holes about an inch or two from the bottom, so it acts as fill line overflow. The media they use is clay rocks. So they fill the container to the top with water, blocking the drain holes temporarily to allow the roots to soak, then removing block to let the water drain out, leaving a water reservoir below the drain holes line. Seems you are almost doing it in the current set-up. It would make draining out water faster.
