Good luck, man! Lots of information on here. I suggest you read, read, and read before even starting your grow. Follow grow threads, grow room threads, and all the advice. Once decided where you want to go whether it's soil, soilless, or hydro, focus on those grows and growers. Ask questions, but first do a little home work here. Most of the answers are repeated many times. It starts to make more and more sense.
Once you have a plan, grow, baby, grow!
