By bubbleponics are you talking about DWC?? I am not quite sure what bubbleponics is. If it is DWC, then I would suggest Hyrdoton. Maybe even cut a rockwool cube half way through, open it up, lay your clone in there, then plant it in the hydroton. LIke I said, I don't know if this is the setup you are talking about, then this is my suggestion. If its not, sorry I wasted your time.
