They hang in the water. Longer cuttings make reservoir top offs less frequent. They could be all the way to the bottom as long as there's no old vegetation left below the plug.Do the cuttings hang in, or just above the water line?
The open sites like removed old shoots will create more roots sites to form. Longer cuttings is better just for the ease of use, and they also have more meat on their bones.
