from what i understand, the blue spectrum of light is only responsible for certain things in photosynthesis. in part for chlorophyll a, chlorphyll b and phycoerythrin and (almost) all of the carotenoids. and the very beginning of phycocyanin.

so i'm not sure if the blue light running 24 hours would be of benefit. i have no scientific proof of this, it's just a hypothesis.

headshake Reviewed by headshake 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
