Im looking into getting one of these to replace my 3x3 mother tent with a flowering scrog. I'm really not finding much on good brands. Lots on bulbs though. I would like a detached ballast as that just makes more sense to me but I remember reading that those are cheaper set ups? Is there a decent set up someone can recommend? If all goes well id like to replace my 1600 watts of hps in my 4x8 with 5 315s Thanks for any help..
