If you're just starting out, don't fill your head with info. that is not needed at the time. Skim the basics, then concentrate on the first step, once you get the first step beat, then move onto the next and focus only on that stage.

Growing comes in 3 basic steps: Germination, Vegetative, and Flowering.

Read about germination, concur that step, then move onto the next. That's what I did anyways and it gave me a good handle on each step in great detail.
