Just finish my Disa setup. Need some last minute clarification.

[Kevin_PR]

Hello forum. I have a Disa uniflora coming in soon and I just finished the setup, so I wanted to ask a few questions to clarify. Well, let me explain the setup first. sorry no camera you gotta visualize

Materials:
Large 24" clay pot
Small plastic 5L bucket
Shallow 12" clay pot
Course river rock (random sizes/ shapes)
Miracle grow potting soil
Old pump from a protein skimmer

Setup
In the large clay pot I place the plastic bucket and filled in the space with soil to keep it fro moving.

I then placed the pump inside the bucket, and cut a hole in the rim of the bucket so tubing will can come out of the bucket.

I placed the smaller pot on top of the plastic bucket and put the tubing so it will spillinto the small clay pot. I then filled it with the gravel

I planted low growing fern in the area between the 2 pots that has soil.

My hopes is that this will keep the water cooler than just leave the plants soaking. I can leave the pump on all day because I adjusted the flow so that water level will reach the rim of the small pot but not exceed it. Also since the medium has perfect drainage and am using a pump from a protein skimmer the area around the roots, including the water, is going to be super oxygenated.

Ok so what I need clarified is can they grow with their roots submerged in the moving water or should I put it in intervals. I read they grow near rivers and seeps and have seen the pics of them posted by "King", but I just wanted to reassure myself from someone who knows.

I guess it was more of a question than questions.
