he said he can't use one duh u gotta read b4 posting soemtiems man yes u can use that for flowering however as everyoen will tell u on here u won't yeild as much from a cfl compared to an hps or mh light setup warm white is what u want for flowering so to answer ur ? yes u can use it
well from my setup i noticed buds twice the normal size as well and accelerated vegatative growth my plants grew more in three qweeks then my friends did (he wasn't using co2)
the one from home depot for $70 comes with the ballast i just bought it 2 days ago
all u have to do
is buy an extension cord
strip it
and re wire it so u can plug it into a wall outlet u';ll be good to go
in all honesty peopel on here tell u one plant per pot yet i have 3 going in one pot and they are all female and they were grown undfer flouro's the whole time they are doing amazing so it depends u just have to watch them for signs of defienceies thats all
