4x4x7 with an a/c in the window. What's next?

Hello Everyone, looking into growing my own medicine for the first time, any suggestions would be greatly appreciated. I have done a little bit of homework and I will ask yous guys about what I have looked at so far:

Growlabs gl120? / Best Choice products 1000watt hps+mh air cool tube digital grow light? /hydroton? / will be growing 6 plants but not sure how yet. was thinking of ebb & flow with 6 5 gallon buckets? things I'm not too sure about::: ventilation,nutrients,humidity,room temperature, and how many vents or ports will I need coming into and out of the room with how many different kinds of fans. Has anyone used this brand of lighting? Looks like low price but u get what u pay for, so if I need a better brand no prob,,,,quality comes first, remember these are my lungs and I want to take good care of them, thank you

I would go & read in each sections & determine which setup best suits you. There's a lot of diffrent ways of doing things. Being your first grow I would do it in soil, because its very forgiving if you happen to mess up, & it does happen. Once you decide which way to go, your questions can be answered more correctly to your situation.
