Net Pots in Water?

[R.K. Castillo]

Another question to go along with the media in net pot on raft question I asked a couple days ago.  

How deep are you net pots in the water?  

Right now my net pots are probably 85% in the water and this seems to keep the hydroton wet all the time and I was thinking it was too deep in the water?

I believe 3/4 of the net pot should be inserted in water to Give a chance for root breathing.:)
