I would treat it like a clone. Use a double tray. One to hold the RW or Rooter with holes to drain and a full tray to set that one inside of. Keep the medium moist but not soaked and never dry. (if the medium sits in water it will wick it up and drowned the plant. It must be able to drain.)
Once you see roots poking out of the RW or Rooter, then you can get it going in your net pots. Water level touching the bottom of the net pots until roots come though that, then drop your level 3" below the net pot.
