from what i have learned
i would suggest
1] grow in soil [like foxfarm and use perlite]
2] go to home depot and get some plywood and make a grow box
3] start small with like a 400 or 600 wat digital ballast [hps]
4] get cfl's or even cheap floroscent lights to veg.
5] go to camping store and buy space blanket to line the inside of the box
6] get a fan
7] drchronic.com for some good seeds [very reliable]
8] expect to learn by making mistakes

thsi set up shouldnt cost to much and if done right you have more than a few oz's of high quality bud every couple of months
