The Best...?

Being a first time grower, I have been doing a lot of research as of late. I know with anything it is always difficult to determine what is the "Best". For me however, it ultimately comes down to quality. Price just determines whether I can afford it or not . http://www.youtube.com/watch?v=teDlsFbNqDo&feature=rec-HM-r2 , would like some feedback from anyone that has used Advanced Nutrients or any other experienced growers, Thanx.

I've used AN for my last two grows and you can go look at my journals and see for yourself. Great products!! but they are only great if you dont mind spending a bit more and most importantly, use them correctly.
