Hey, triv goin dro soon, need some help on setup.

Hey mates, Im going to start a hydro grow within 4-6 weeks, Im moving into a new home and I plan to grow 6 plants for my smokes. Now I plan to order a few things online but Im not going threw paypal nor ebay, they seem a bit too heaty right now. Correct me if Im wrong but DEA cannot track my moneyorder for this purchase, unless ofcourse it is registerd?

Alright well back to business. Most of my hydro knowledge is going to be coming from my buddy who's teaching me hydro. Im learning the basics of it so I could finally do so dro my self.

The following list is my shopping list :

1.BGH 6 plant system. http://www.bghydro.com/BGH/itemdesc.asp?ic=HGS6&eq=&Tp=

Now Im exchanging the 400w light for a 1000w HID.

2.1000w HPS/MH light ballast. I decided to go with the High reflective reflector for a little extra cash, and also turned it into a 1000w MH/HPS SSX ballast, and a 1000w HPS Enhanced(145,000 lumens) bulb.

Now please, if you think Im missing anything please do let me know, I have nutrients or will be purchasing some more. Also, where can I purchase some rockwool to start my seedlings in.
