as far as wiring everything I'm all set with that ... my brother is an electrician and has experience with setting up indoor grow rooms.

as far as 100w lights over 600w lights,
its a sog setup so penitration is not an issue considering the plants will be kept very short with one main cola. The advantage of a 600w light is a dual mh/hps ballast setup. I can flip from mh to hps in seconds and there cheaper to run.

as far as cooltubes go ... I dont have any windows in this room so the only cooling will be through heavy ventalation and portable ac units. cool tubes have alot less heat to deal with and from my experinece in the past cooled hoods produce way more heat then cooltubes. If I had the means to install a large ac unit I wouldnt use the cool tubes. As far as thye bat wing goes the internal reflectors in cool tubes suck so a large bat wing reflector does the job ... if I need to run more lights then I will.
