you mean Mh not Mv im assuming and fl you mean flourescents or cfls i read on here that its about .5g for ever 4w of energy with mh bulbs but i could be wrong and as for cfls im currently aiming for 1/2-1 ounce per plant witha 3 foot growspace 3'3'3' i'd try to fit in there about 9 female clones and go for ballpark 7 to 10 ounces..always expect less then what you need and plan ahead
