just about to start to flower i have two choise of what lights i can use 1st is 400w mh.....2nd is 250w + 70w hps which would you go for out of the two choises ?
i mean the colour of the hps light has more red and the mh has more blue,and the hps,s red is better for flowing......so i was thinking a few less watts but the right colour frequancy or vice versa ?
