Carnations, rooted with air stimulated roots

Want an idea for getting more roots? 

Of course rooting Carnations with the Q Plug is currently used through-out the world, but the Carnations in these pictures are rooted in the Q Plug surrounded by air. That's right, instead of using the cells as intended the rooting trays were turned upside down and the spaces were used between the cells to put the Q Plugs in with the desired spacing. That's why you see the roots coming out right from the top and completely engulfing the Q Plug.
