18/6 or 20/4 the whole way through its very debatable on which is better its just personal preference really

i run 400 watts mixed 2500 k 5000 k and 6000 k and my lights run 24/7 the only reason for the dark period is cool down for your hps or for led's with a duty cycle if a plant requires dark then it is not a true auto
