gman...everything you need is on this page at bghydro:
http://www.bghydro.com/BGH/items.asp...atus=0&Tp=&Bc=

Once at this page, click on top system for 169. bucks and there is a PDF format instruction page. If I were starting now with the knowledge I have now; I would start with this...It is the simplest way to go, and bghydro has put together a package that will get you started within hours of opening those boxes.

If you are sold on waterfarm, get it. It is a great commercial system you can add to and add, to get as many sites as you want to produce. I am sure that the waterfarm page, at link I gave you, will also have instructions.
The point is that BGhydro is very affordable, consistently the most all around competitive hydro store on the net.
whatever you buy from them, will come with instructions; Or, I can say with confidence that they will walk you through your set-up; If necessary.

bghydro. customer service is paralleled by only a few...without a doubt. There is Old School knowledge here that I find priceless!
I also like sunsethydro(freeshipping), and greencoasthydro(AN people). Good Luck, I hope this helps. lw
