Well if your willing to pay for 230w of power to use the cfls go to a 250HPS for a huge advantage!!!which is better 70w hps or 10 23watt cfl
you cant add lumens
also, who cares about lumens if they are in the wrong spectrum you douche ???
Not all the light from a HPS is usable throughtout the cycle of a plant, therefore it is not using 100% of light spectrum being emitted,need to be taking into account for the different stages of growthwho said anything about spectrum?
