I agree, this seems like a circular argument. I've grown one plant in a 1x1x3 foot space with 5 CFL's and honestly yileded fined. Take into account it was 5 motherfucking lights for a tiny little ass space, so I better have yielded something descent. However, if you're thinking of growing anything more than that, in a larger space, I'm agreeing with these fellas, HID is the way to go. I understand they may be initially expensive, or depending where you are, hard to come by, but if you're seriously interested in cannabis propogation, than you should invest. Again, personal choices, you definitely can grow fine with CFL's its more like the difference between making 9 bucks an hour or 20. You probably are gonnna have to work a bit harder but they pay off is obviosuly better (i realize this is a subjective analogy). Anyways, HID's the way to go if you wanna grow pro. and as for PAR, seems irrelevent to me.
