If you are planning to use flourescents (which i am because of my small grow space and i cant afford to let out any more heat) use cool white flourescents for veg, and warm white combined with cool white (put lights as close as possible) for flowering and for clones.

I have herd that using cool white and warm white together from the start bring exellent results. try to use 1200 lumes per square foot. so per square foot have 1 cool white and 1 warm white....if you understand what i mean....? Dont use and aluminuim like reflectors, they bring out alot of heat. Use mylar. Or paper, photo paper which are resonbley cheap, shiny side out.

peace!
