well you can "flower" with both kinds of cfl's for sure waht ever the light temp of those is since flowering is started by hours of light and not by light temp
but "flowering" with cfl's eigther waste money or time, and mostly both since it would take about 800W, in terms of real Watts, to get the same output of a single 400W HPS.
so get yourself a 400W HPS, they start at around 100-120bucks at ebay, or by a real descent on in a hydro shop. this is a really fine shop were you get big bang for the buckhttp://www.htgsupply.com/index.asp air-cooled 400W HPS kit with everything to start with goes for little as 170bucks, which is for the value cheaper then dirt.
