The traditional advice regarding transplanting seedlings is intended for a situation where you are plucking seedlings from a rather thickly-sown, mass-planted flat, and in doing so, disturbing the roots. It was good advice, but originated years before the various grow-cube solutions were invented.
When using grow-cubes you're not so much "transplanting" as you are "potting-on", which gives you a lot more flexibility. You can let them sit a little longer if you like, since they're a lot less likely to become seriously root-entangled with their neighbors. It's probably better to let them get a little larger, so that they have a well-established root system when being moved up to the next larger pot.
