I brew 25 litre batches but only 21L ends up in the cube. The rest goes into sterilised lab bottles (which are like little no chill cubes) and when I'm ready to pitch, I reboil this extra wort and do the flameout addition in a coffee plunger and chill back to pitching temperature. So the late hops never go anywhere near the cube.
Works very well with hop flowers.
Argon does something similar but uses a bit more wort and chills the cube in the fridge first so that when he pitches the hot hoppy goodness the beer all ends up at pitching temperature.
Edit: I guess that a flameout addition done in a small quantity of wort could possibly have a different outcome to one done in the full wort volume?? If so then Argon's method would more closely resemble a full-wort addition. However my method is a lot quicker and simpler. Swings roundabouts
