    LED Flowering at 12/12 or 20/4

    Howdy Folks, As the title suggests i have a bit of a dilemma, I have always used 12/12 for flowering time but with my new Viparspectra V900 it suggests in the book that came with it to use 20/4 for flower, not sure why this would be, any thoughts on this? Cheers Z
