I think you would be crazy to buy that for $554 plus shipping probably $600. If I were you I would go on ebay and buy a 400 mh for $120 with shipping and be done with it. I surely doubt it out performes a 1000 mh. I even saw those on ebay for half that price that site is selling it for. maybe you can just buy it of ebay!!:thumbsup: The holes on the settup are as far as you want them to be, if you want more plants in a smaller area I would put them 6 in.
