I did hydroponics right from the beginning its pretty simple, too. It kinda depends on how much room you have and what your objectives are. Me, I wanted a small stealth cabinet and not too powerful of lights so that led me to scrog, which therefore leads me to hydro. I made my own hydro setup its not hard if you're mechanically inclined. But if you have space for a couple of grow rooms then you can start with soil, too. Either-or.
How big a harvest did you want? Is it just for personal use and a few friends, or do you want to deal? Its never a bad idea to start small and as you learn you can improve your system. After every grow I refit my room and every harvest has been better quality and better yield.
There's lots of stuff you can buy on Amazon and elsewhere. For starters, I'd look for a 250W or 400w HPS for flowering, and 150W and up Flourescent or MH for veg. With cooltubes, preferably. A fan/carbon filter combo for each room (or at least the flower room, veg room nowhere near as stinky) and either a couple of tents or build a couple of rooms. Me, I have both a flower and a veg chamber in one of those portable closets you can buy at Home Depot, with one fan/filter for the whole cab. Perennial scrog; fairly small footprint and still can generate 5-7 zips every 10-12 weeks. Well, that's an estimate; I just upgraded to 400W hps so that's what I'm hoping for.
And final advice, don't waste your time with bag seed! Spend $40 at Nirvana and know that your efforts will be worthwhile!
