He said these were not his grows. FDD is all about the CFLs. who needs a thousand watts of lite. do you know how much energy those lights take? cuz i don't and i need help. hahahaha
here's some math for ya
500w x (how ever many hours the light is on this will be on 24 hours a day) x (the cost per kw here a kw is $0.06)
soo....
500 x 24 x 0.06 = 720
720 / 1000 (1000w in a kw) = $0.72 (roughly a day)
$0.72 x (roughly 30 days in a month) = $21.60 a month just for the light(s)
I've seen some iight yeilds from CFLs but thoes are either HPS or MH or realy srong CFLs cuz the farther away the lights are then the less effective they are
