I'd recommend Ed Rosenthal's "Marijuana Grower's Handbook" here: http://www.amazon.com/Marijuana-Growers-Handbook-Complete-Cu...

You can find more gems by looking at Oaksterdam's recommended reading lists for their classes: http://oaksterdamuniversity.com/students/textbooks/ (scroll down the page a bit to see the books)

And of course, the Oaksterdam classes are a great resource if you're nearby.
