Ok cool, and 400w mh or hps would be good for about how many plants ?

it is an awesome deal. Pretty much gives yuo everything you need to get started. Something to think about is upgrading your reflector into something with a cool tube. For that matter, if you get a cool tube and its own fan you could easily handle a 600 watter in there. http://htgsupply.com/Category-Air-Coolable.asp vented hoods
