Look into water farms, capable of growing tree's. Heath Robinson; he grew 2 plants in single water farms each and yielded 74 oz's, using 2 600w hps lights. and it was so easy to grow using the farms, i'd consider looking into them.
otherwise i find flood & drain system easiest to start with.
Despite what everyone is going to say, as a lot will try and tell you hydro is hard work and its shit doesn't work for first growers etc, i'd like to say make your own decision. Are you going to be there to water it every second day or are yu like me and like to change water just once a week. i personally like waiting a week and seeing the massive improvements that are made on a weekly basis rather then the tiny growth done in a few days. (doesn't hurt to have a look every few days to make sure all is going good, and if you know what you're doing, is most of the time)
and the ones that tell you that hydro is easier to fuck up in, are usually the one's that didn't research themselves and fucked up themselves.
hydroponics is a piece of cake along as you do sufficient research.. fuck my hydro setup cost me $40 and in turn i'm looking at yielding at least 4 oz's, nothing impressive but for a $40 setup and a first grow i couldn't be happier.
