a cheap yet reliable 1000w hps lamp/ ballast?? probably need a pretty good size fan too 6" exaust?http://forum.grasscity.com/images/icons/icon10.gif
I wouldn't skimp on the ballast, I would go with Galaxy or a Lumatek. You''ll need a high CFM 6" fan, don't bother with an 8" for a single light setup. Hope this helps! Feel free to check my journal for a 1000w 4x4 tent grow. I'm detailing as much as I can, and if you don't see something, feel free to ask.
