You might be able to duplicate this by diverting some outflow from a pump over the Phrag medium.

I will report back to everyone next month, I am going to Colombia and am visiting Phrag habitat
. But if you read up, they grow in saturated conditions.
I grow mine in humidity trays with the grate removed, so 2.75" of water, and until I recently put in a small aquarium pump, it was standing water. I don't think it's hurt the plants, and another excellent grower locally also has her phrags in standing water.
I saw another facility where they move their phrags into a basin for a few hours, then flood it with water, drain it, flood it again, repeat. Seems silly in a drought prone area but people will do anything for their orchids.
