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.
RackitMan Reviewed by RackitMan on . Blue light after 'dark'? Has anyone here tried using pure blue light (LED or actinic fluoro) during the 'dark' or night phase when in 12/12 light cycle to keep photosynthesis going without interrrupting the flowering phase? I have one of the newer 50 watt blue LED panels and may give it a try, but would like to get some feedback first. Rating: 5
