First mm of stem has started "seeing"* the light for the first time. * The plant does not have eyes, and do therefor not "see", but rather 'sense' the light with its whole being, one can asume; as in where it is hit with light, the roots will grow the oposite way, while the stem will follow the way of the light — as we must now. Follow the spark of light that remain, so that we can remain.
