Sounds like pretty much one thing. It really doesn't matter a whole bunch. Just make sure you have the basics correct for your first grow and you will be doing good. Most systems produce similar results, but I highly recommend a DWC system for begginers. You'll get great results if you do it properly, and it's very easy. Search Emily's Garden. This is a great set up, and you could build a better one yourself for less than half.

People try to compare systems over and over, but it just doesn't matter. A good DWC system run properly will beat an expensive NFT or fog system if just one or two things are not done quite right. The secret is, no matter what you do, get your basics right, then force as much oxygen as possible to those roots. This is what will get you the big yields. It doesn't really matter how it's done.
