You should definitely use a higher ratio of blue (more blue than red) for vegetative and a higher ratio red (more red than blue) for flowering. You should also have at least some red in vegetative and at least some blue in flowering...both wavelengths are needed.

CHEAPER LED UFO, 100 bucks. could i use the mixed blue red 225 led light to grow from seed to flower? or should i use blue for veg, then all red for flower? these lights have more leds than the UFO, what is better? i want it to supplement the CFLs i already have.
