Hey Jack, I would have invested in an HPS/ballast had I gotten the same deal that I got on the MH and ballast (free). I will likely get one soon anyways, as I want to scrog and Ill need separate chambers for veg and flowering.
Actually I used 125watts of cfls to get it about halfway, then switched over to the mh when it was given to me about 2 weeks ago. I can say that I saw immediate results in new growth right after changing to the mh, but the cfls did keep the nodes pretty close together.

Hey Dutch Pimp, btw, I checked the rated kelvins on the GE datasheet, its 3200k.

thanks all:rastasmoke:
