not to sure on this one but i will take a guess and say, no. There wont be any benefit. Plants depend on both red and blue light to photosynthesize properly, and blue is mostly just for internode length. Probably would make your plant hermie or maybe just make it do some crazy shit none of us have ever seen. Just my opinion. Im sure i could ramble on a little more, but i dont think i would be telling you anything you dont know, lol. Try it, and let us know, definitely an interesting experiment.
metalhead419 Reviewed by metalhead419 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
