To the best of my knowledge, 12/12 red light signals the plant to flower whereas blue light does not trip flowering on or off. Therefore, using pure blue during the normal 12 hour 'off' period should allow photosynthesis to continue without disturbing the flower cycle. This should allow for greater/faster growth if my hypothesis is correct.

As I only have time/space for 2 mini grows per year it is difficult for me to test at this time.
