Just start a hempy bucket or two, under some T5s or CFLs - just to gain some experience. Buy a used Grower's Bible off of Amazon. Read what's on this site and the many many others like it. When you get stuck - ask a question.

I recommend a hempy bucket as it's very easy, also as easy as soil and if any mistakes are made, they're corrected fast. In soil, it takes a while to correct any mistakes.
