so CFL's or a MH/HPS combo? obviously heat is a issue since ill be using a 3x3x6 or so cabinet,and obviously im not wanting any "spikes" in my electric bill or none of that,so im stuck here,i keep going back and forth from buying prob a t5 4 bulb set up or a nice 400watt mh/hps combo i cant make my mind up. is it going to be a serious problem getting the heat out of there with a hps,the key to this setup obviously is being low key,so i dont want loud exhuast fans going,air ducts everywhere,etc...basically i want it to someone will look at this cabinet and not see air ducts and big fans coming out of everywhere....i ordered my seeds and they are here,now i just gotta make my mind up on what to buy for this cabinet setup,i know im making this harder than it is
