I'm a newbie Grower, still on my first grow figuring things out. From my personal limited experience, the information you can get here on the RIU forums from other peoples answered questions plus the amazing people that reply to questions I think it's hard to make any huge mistakes.
I started my grow in Soil and was amazed how quick they were growing, saw a post from WidowMaker about Grow Videos and I duplicated the mr. green grow setup (hydro) then modified it with suggestions from several people here in the forums and my local hydro store. Due to the advanced speed of the grow process. or at least my perceived speed difference. I made the move to hydro and would never go back. I can easily dispose of hydro waste water, not many pounds of dirt. it seems like there is less waste using hydro, now Cost of nutrients does add up. but it should be well worth it, with an excellent quality product you can be proud of. ph meter is a huge neccesity and I like having a meter to check the ppm on my nutrients to double check my mix. I have overdone it on nutrients for 1 entire week and my plants got a little burned, but in a few days they bounced right back.
Do the research, and give it a try. I never thought I would be so into growing until I saw my girls go from seed to the amazing huge plants they are now. you already have a huge advantage, the people here in RIU.
