I agree with crazywill, learn what you have now and then decide if you even want to try something else. I did three grows with my leach tray set up and now that I have a little growing experience i built my new sytem to fit my needs plus a little experimentation. And read as many threads on here as possible and you will be well on your way to obtining a knowledge of all the different set ups. If you want to see the system I built check out my thread - http://boards.cannabis.com/hydroponi...ew-system.html
