I tried it once in the past. Fist reply was rotting within few days. Remember a pic of delenatii in situ took by Mr. Cahn. Roots were always wet by dripping water but on the surface of rocks so they could breathe.
To me, that reinforces my thoughts on root growth: Yes, they need both air and water, but they can grow in a way that makes different conditions acceptable.
Move a plant into semi-hydroponics, for example. You MUST pot it with the roots above the static reservoir, or they will rot. However, over time, the plant will grow its roots down into the reservoir, so will be submerged at all times, but do not rot, and in fact, they plant will do better than ever.
In the case of the "ebb and flow" nature of the concept in this thread, I believe the best option would be to have the tray be deep, have the pump flood it completely on a timer, then let it drain.
That could be accomplished by having a standpipe to set the maximum depth, but have a smaller hole in its base (or the tray bottom) to allow the water to slowly drain. (I am assuming the pump can lift more water than the hole can drain per unit time.)
