No problem man u worries are over Just do what I did I spent about 180 on my system. It works pretty good I mean I'm happy with the results. Just get a 400w HPS system (should come with the HPS-bulb) Then buy the MH conversion bulb which is about 40bucks then shipping and u good. Just remember I'm having problems with the heat and cant keep my closet door shut. So just take that info and use it. Here are 2 websites u can use that are good I used insidesun but the other ones looks really good maybe even better.
